A Drosophila TNF-receptor-associated factor (TRAF) binds the ste20 kinase Misshapen and activates Jun kinase. (1/46456)

Two families of protein kinases that are closely related to Ste20 in their kinase domain have been identified - the p21-activated protein kinase (Pak) and SPS1 families [1-3]. In contrast to Pak family members, SPS1 family members do not bind and are not activated by GTP-bound p21Rac and Cdc42. We recently placed a member of the SPS1 family, called Misshapen (Msn), genetically upstream of the c-Jun amino-terminal (JNK) mitogen-activated protein (MAP) kinase module in Drosophila [4]. The failure to activate JNK in Drosophila leads to embryonic lethality due to the failure of these embryos to stimulate dorsal closure [5-8]. Msn probably functions as a MAP kinase kinase kinase kinase in Drosophila, activating the JNK pathway via an, as yet, undefined MAP kinase kinase kinase. We have identified a Drosophila TNF-receptor-associated factor, DTRAF1, by screening for Msn-interacting proteins using the yeast two-hybrid system. In contrast to the mammalian TRAFs that have been shown to activate JNK, DTRAF1 lacks an amino-terminal 'Ring-finger' domain, and overexpression of a truncated DTRAF1, consisting of only its TRAF domain, activates JNK. We also identified another DTRAF, DTRAF2, that contains an amino-terminal Ring-finger domain. Msn specifically binds the TRAF domain of DTRAF1 but not that of DTRAF2. In Drosophila, DTRAF1 is thus a good candidate for an upstream molecule that regulates the JNK pathway by interacting with, and activating, Msn. Consistent with this idea, expression of a dominant-negative Msn mutant protein blocks the activation of JNK by DTRAF1. Furthermore, coexpression of Msn with DTRAF1 leads to the synergistic activation of JNK. We have extended some of these observations to the mammalian homolog of Msn, Nck-interacting kinase (NIK), suggesting that TRAFs also play a critical role in regulating Ste20 kinases in mammals.  (+info)

Identification of sonic hedgehog as a candidate gene responsible for the polydactylous mouse mutant Sasquatch. (2/46456)

The mouse mutants of the hemimelia-luxate group (lx, lu, lst, Dh, Xt, and the more recently identified Hx, Xpl and Rim4; [1] [2] [3] [4] [5]) have in common preaxial polydactyly and longbone abnormalities. Associated with the duplication of digits are changes in the regulation of development of the anterior limb bud resulting in ectopic expression of signalling components such as Sonic hedgehog (Shh) and fibroblast growth factor-4 (Fgf4), but little is known about the molecular causes of this misregulation. We generated, by a transgene insertion event, a new member of this group of mutants, Sasquatch (Ssq), which disrupted aspects of both anteroposterior (AP) and dorsoventral (DV) patterning. The mutant displayed preaxial polydactyly in the hindlimbs of heterozygous embryos, and in both hindlimbs and forelimbs of homozygotes. The Shh, Fgf4, Fgf8, Hoxd12 and Hoxd13 genes were all ectopically expressed in the anterior region of affected limb buds. The insertion site was found to lie close to the Shh locus. Furthermore, expression from the transgene reporter has come under the control of a regulatory element that directs a pattern mirroring the endogenous expression pattern of Shh in limbs. In abnormal limbs, both Shh and the reporter were ectopically induced in the anterior region, whereas in normal limbs the reporter and Shh were restricted to the zone of polarising activity (ZPA). These data strongly suggest that Ssq is caused by direct interference with the cis regulation of the Shh gene.  (+info)

High-throughput screening of small molecules in miniaturized mammalian cell-based assays involving post-translational modifications. (3/46456)

BACKGROUND: Fully adapting a forward genetic approach to mammalian systems requires efficient methods to alter systematically gene products without prior knowledge of gene sequences, while allowing for the subsequent characterization of these alterations. Ideally, these methods would also allow function to be altered in a temporally controlled manner. RESULTS: We report the development of a miniaturized cell-based assay format that enables a genetic-like approach to understanding cellular pathways in mammalian systems using small molecules, rather than mutations, as the source of gene-product alterations. This whole-cell immunodetection assay can sensitively detect changes in specific cellular macromolecules in high-density arrays of mammalian cells. Furthermore, it is compatible with screening large numbers of small molecules in nanoliter to microliter culture volumes. We refer to this assay format as a 'cytoblot', and demonstrate the use of cytoblotting to monitor biosynthetic processes such as DNA synthesis, and post-translational processes such as acetylation and phosphorylation. Finally, we demonstrate the applicability of these assays to natural-product screening through the identification of marine sponge extracts exhibiting genotype-specific inhibition of 5-bromodeoxyuridine incorporation and suppression of the anti-proliferative effect of rapamycin. CONCLUSIONS: We show that cytoblots can be used for high-throughput screening of small molecules in cell-based assays. Together with small-molecule libraries, the cytoblot assay can be used to perform chemical genetic screens analogous to those used in classical genetics and thus should be applicable to understanding a wide variety of cellular processes, especially those involving post-transitional modifications.  (+info)

Interleukin-8 receptor modulates IgE production and B-cell expansion and trafficking in allergen-induced pulmonary inflammation. (4/46456)

We examined the role of the interleukin-8 (IL-8) receptor in a murine model of allergen-induced pulmonary inflammation using mice with a targeted deletion of the murine IL-8 receptor homologue (IL-8r-/-). Wild-type (Wt) and IL-8r-/- mice were systemically immunized to ovalbumin (OVA) and were exposed with either single or multiple challenge of aerosolized phosphate-buffered saline (OVA/PBS) or OVA (OVA/OVA). Analysis of cells recovered from bronchoalveolar lavage (BAL) revealed a diminished recruitment of neutrophils to the airway lumen after single challenge in IL-8r-/- mice compared with Wt mice, whereas multiply challenged IL-8r-/- mice had increased B cells and fewer neutrophils compared with Wt mice. Both Wt and IL-8r-/- OVA/OVA mice recruited similar numbers of eosinophils to the BAL fluid and exhibited comparable degrees of pulmonary inflammation histologically. Both total and OVA-specific IgE levels were greater in multiply challenged IL-8r-/- OVA/OVA mice than in Wt mice. Both the IL-8r-/- OVA/OVA and OVA/PBS mice were significantly less responsive to methacholine than their respective Wt groups, but both Wt and IL-8r mice showed similar degrees of enhancement after multiple allergen challenge. The data demonstrate that the IL-8r modulates IgE production, airway responsiveness, and the composition of the cells (B cells and neutrophils) recruited to the airway lumen in response to antigen.  (+info)

Concomitant activation of pathways downstream of Grb2 and PI 3-kinase is required for MET-mediated metastasis. (5/46456)

The Met tyrosine kinase - the HGF receptor - induces cell transformation and metastasis when constitutively activated. Met signaling is mediated by phosphorylation of two carboxy-terminal tyrosines which act as docking sites for a number of SH2-containing molecules. These include Grb2 and p85 which couple the receptor, respectively, with Ras and PI 3-kinase. We previously showed that a Met mutant designed to obtain preferential coupling with Grb2 (Met2xGrb2) is permissive for motility, increases transformation, but - surprisingly - is impaired in causing invasion and metastasis. In this work we used Met mutants optimized for binding either p85 alone (Met2xPI3K) or p85 and Grb2 (MetPI3K/Grb2) to evaluate the relative importance of Ras and PI 3-kinase as downstream effectors of Met. Met2xPI3K was competent in eliciting motility, but not transformation, invasion, or metastasis. Conversely, MetP13K/Grb2 induced motility, transformation, invasion and metastasis as efficiently as wild type Met. Furthermore, the expression of constitutively active PI 3-kinase in cells transformed by the Met2xGrb2 mutant, fully rescued their ability to invade and metastasize. These data point to a central role for PI 3-kinase in Met-mediated invasiveness, and indicate that simultaneous activation of Ras and PI 3-kinase is required to unleash the Met metastatic potential.  (+info)

Polarized distribution of Bcr-Abl in migrating myeloid cells and co-localization of Bcr-Abl and its target proteins. (6/46456)

Bcr-Abl plays a critical role in the pathogenesis of Philadelphia chromosome-positive leukemia. Although a large number of substrates and interacting proteins of Bcr-Abl have been identified, it remains unclear whether Bcr-Abl assembles multi-protein complexes and if it does where these complexes are within cells. We have investigated the localization of Bcr-Abl in 32D myeloid cells attached to the extracellular matrix. We have found that Bcr-Abl displays a polarized distribution, colocalizing with a subset of filamentous actin at trailing portions of migrating 32D cells, and localizes on the cortical F-actin and on vesicle-like structures in resting 32D cells. Deletion of the actin binding domain of Bcr-Abl (Bcr-AbI-AD) dramatically enhances the localization of Bcr-Abl on the vesicle-like structures. These distinct localization patterns of Bcr-Abl and Bcr-Abl-AD enabled us to examine the localization of Bcr-Abl substrate and interacting proteins in relation to Bcr-Abl. We found that a subset of biochemically defined target proteins of Bcr-Abl redistributed and co-localized with Bcr-Abl on F-actin and on vesicle-like structures. The co-localization of signaling proteins with Bcr-Abl at its sites of localization supports the idea that Bcr-Abl forms a multi-protein signaling complex, while the polarized distribution and vesicle-like localization of Bcr-Abl may play a role in leukemogenesis.  (+info)

Telomerase reverse transcriptase gene is a direct target of c-Myc but is not functionally equivalent in cellular transformation. (7/46456)

The telomerase reverse transcriptase component (TERT) is not expressed in most primary somatic human cells and tissues, but is upregulated in the majority of immortalized cell lines and tumors. Here, we identify the c-Myc transcription factor as a direct mediator of telomerase activation in primary human fibroblasts through its ability to specifically induce TERT gene expression. Through the use of a hormone inducible form of c-Myc (c-Myc-ER), we demonstrate that Myc-induced activation of the hTERT promoter requires an evolutionarily conserved E-box and that c-Myc-ER-induced accumulation of hTERT mRNA takes place in the absence of de novo protein synthesis. These findings demonstrate that the TERT gene is a direct transcriptional target of c-Myc. Since telomerase activation frequently correlates with immortalization and telomerase functions to stabilize telomers in cycling cells, we tested whether Myc-induced activation of TERT gene expression represents an important mechanism through which c-Myc acts to immortalize cells. Employing the rat embryo fibroblast cooperation assay, we show that TERT is unable to substitute for c-Myc in the transformation of primary rodent fibroblasts, suggesting that the transforming activities of Myc extend beyond its ability to activate TERT gene expression and hence telomerase activity.  (+info)

Leptin suppression of insulin secretion and gene expression in human pancreatic islets: implications for the development of adipogenic diabetes mellitus. (8/46456)

Previously we demonstrated the expression of the long form of the leptin receptor in rodent pancreatic beta-cells and an inhibition of insulin secretion by leptin via activation of ATP-sensitive potassium channels. Here we examine pancreatic islets isolated from pancreata of human donors for their responses to leptin. The presence of leptin receptors on islet beta-cells was demonstrated by double fluorescence confocal microscopy after binding of a fluorescent derivative of human leptin (Cy3-leptin). Leptin (6.25 nM) suppressed insulin secretion of normal islets by 20% at 5.6 mM glucose. Intracellular calcium responses to 16.7 mM glucose were rapidly reduced by leptin. Proinsulin messenger ribonucleic acid expression in islets was inhibited by leptin at 11.1 mM, but not at 5.6 mM glucose. Leptin also reduced proinsulin messenger ribonucleic acid levels that were increased in islets by treatment with 10 nM glucagon-like peptide-1 in the presence of either 5.6 or 11.1 mM glucose. These findings demonstrate direct suppressive effects of leptin on insulin-producing beta-cells in human islets at the levels of both stimulus-secretion coupling and gene expression. The findings also further indicate the existence of an adipoinsular axis in humans in which insulin stimulates leptin production in adipocytes and leptin inhibits the production of insulin in beta-cells. We suggest that dysregulation of the adipoinsular axis in obese individuals due to defective leptin reception by beta-cells may result in chronic hyperinsulinemia and may contribute to the pathogenesis of adipogenic diabetes.  (+info)

Protein structure prediction is an important problem in the post-genome era, which is one possible way to fill the gap between the rapid-growth sequences and the relative small number of proteins with experimentally determined structures. Despite the structural genomics initiatives and biochemical efforts, the cheapest and fastest way to obtain structural information is through prediction algorithms. Structure prediction, even in the absence of homology, is the first step of the sequence-structure-function paradigm. Great progress has been achieved in protein structure prediction during the last decades. The development of high-quality prediction methods has also been boosted by objective community-wide assessment experiments. However, the ultimate goal of protein structure prediction remains far away to reach. New algorithms, theory and advanced prediction techniques are necessary to facilitate the progress ...

The IntFOLD-TS method was developed according to the guiding principle that the model quality assessment (QA) would be the most critical stage for our template-based modeling pipeline. Thus, the IntFOLD-TS method firstly generates numerous alternate models, using in-house versions of several different sequence-structure alignment methods, which are then ranked in terms of global quality using our top performing QA method-ModFOLDclust2. In addition to the predicted global quality scores, the predictions of local errors are also provided in the resulting coordinate files, using scores that represent the predicted deviation of each residue in the model from the equivalent residue in the native structure. The IntFOLD-TS method was found to generate high quality 3D models for many of the CASP9 targets, whilst also providing highly accurate predictions of their per-residue errors. This important information may help to make the 3D models that are produced by the IntFOLD-TS method more useful for ...
Another direction that is being taken is to adapt primary sequence alignment methods to consider secondary and tertiary structure. There are a number of features of proteins integral to their function and interaction with other proteins that are not determined by amino acid sequence alone. Many proteins share functional properties despite vast sequence differences because of the shapes that they fold into. One method of simultaneously quantifying and visualizing these relationships is using a protein structure space map. [¹] Roughly speaking, a Protein structure space map is the result of scoring how well known proteins match, structurally. That score is used as a directional distance used to position families of proteins in relation to each other on a set of axes, closer if they are more similar, distantly if they are more dissimilar. Anyone can look at the structure space map and immediately judge how similar two proteins or protein families are by their proximity on the map.. There are a ...

Interactions at the molecular level in the cellular environment play a very crucial role in maintaining the physiological functioning of the cell. These molecular interactions exist at varied levels viz. protein-protein interactions, protein-nucleic acid interactions or protein-small molecules interactions. Presently in the field, these interactions and their mechanisms mark intensively studied areas. Molecular interactions can also be studied computationally using the approach named as Molecular Docking. Molecular docking employs search algorithms to predict the possible conformations for interacting partners and then calculates interaction energies. However, docking proposes number of solutions as different docked poses and hence offers a serious challenge to identify the native (or near native) structures from the pool of these docked poses. Here, we propose a rigorous scoring scheme called DockScore which can be used to rank the docked poses and identify the best docked pose out of many as ...
One of the major unsolved problems in molecular biology today is the protein folding problem: given an amino acid sequence, predict the overall three-dimensional structure of the corresponding protein. It has been known since the seminal work of Christian B. Anfinsen in the early seventies that the sequence of a protein encodes its structure, but the exact details of the encoding still remain elusive.. Since the protein folding problem is of enormous practical, theoretical and medical importance - and in addition forms a fascinating intellectual challenge - it is often called the holy grail of bioinformatics. The Statistical Structural Biology group focuses on Bayesian, probabilistic models of protein structure and their application to protein structure prediction, protein design and protein structure determination from experimental data (NMR, SAXS), including data obtained from protein ensembles. Recently, we started working on evolutionary models of protein structure evolution.. We are ...
The creation of an automated method for determining 3D protein structure would be invaluable to the eld of biology and presents an interesting challenge to computer science. Unfortunately , given the current level of protein knowledge, a completely automated solution method is not yet feasible; therefore, our group has decided to integrate existing databases and theories to create a software system that assists X-ray crystallographers in specifying a particular protein structure. By breaking the problem of determining overall protein structure into small subproblems, we hope to come closer to solving a novel structure by solving each component. By generating necessary information for structure determination, this method provides the rst step toward designing a program to determine protein conformation automatically. The properties of a protein are largely determined by its three-dimensional structure Voet and Voet 1990]. This statement would seem to simplify the process of understanding proteins and

Scientists from The University of Manchester - part of the Manchester Cancer Research Centre - used a simple protein test that could prove more useful in predicting survival chances for patients with head-and-neck cancer compared to existing methods.. The team, funded by Cancer Research UK, believe the test could allow doctors to choose more appropriate and tailored treatments. Oral cancers, including the tongue and tonsils, are usually associated with tobacco and alcohol intake.. However, increasing numbers of cases are instead linked to human papillomaviruses (HPV) - which occur in younger people and have a different biology and a better prognosis. One approach for detecting HPV-associated oral cancer relies on finding HPV DNA in the tumour sample but these DNA-based tests may not accurately classify the tumour.. Another approach is to use a marker of HPV rather than testing for HPV DNA directly. The p16 protein usually disappears in tumours that are not caused by HPV infection and has been ...

Understanding the function of complex biomacromolecular assemblies requires detailed knowledge of the structure and dynamics of the individual molecular components as well as of their interactions within complexes. Fluorescence based methods offer the possibility to measure protein properties and interactions with a high sensitivity and selectivity. The advent of bright and more photo-stable fluorescent dyes and an enormous methodical and technical improvement of high resolution fluorescence spectroscopy and microscopy enabled studies on proteins even at a single molecule level. Due to the fact that single molecule techniques provide information on the distribution of parameters characterizing the biological macromolecule, these methods are often the approach of choice to clarify and better understand the structure and function of proteins.. ...

Finding the ends of a protein chain is easy for a human being. But writing code to find the ends of the protein chains in any PDB file in a general manner seems challenging.

If anyone has other ideas, especially simpler methods, please let me know! Why? I would like to have buttons in FirstGlance that zoom in on the terminal residues (with coordinates) of a protein chain for any PDB entry displayed. Also, in the /Charge/ view in FirstGlance, I would like to show whether the terminal amino and carboxy residues that have coordinates are charged -- that is, whether they are the termini of the experimental protein, or whether the actual terminal amino acids are missing coordinates. Or whether the terminal amino acids are blocked. I prefer to rely on sequence numbers as LITTLE as possible because they are not required to increase monotonically between the N and C termini, ...

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Background The protein structure prediction problem is one of the most challenging problems in biological sciences. Many approaches have been proposed using database information and/or simplified protein models. The protein structure prediction problem can be cast in the form of an optimization problem. Notwithstanding its importance, the problem has very seldom been tackled by Constraint Logic Programming, a declarative programming paradigm suitable for solving combinatorial optimization problems. Results Constraint Logic Programming techniques have been applied to the protein structure prediction problem on the face-centered cube lattice model. Molecular dynamics techniques, endowed with the notion of constraint, have been also exploited. Even using a very simplified model, Constraint Logic Programming on the face-centered cube lattice model allowed us to obtain acceptable results for a few small proteins. As a test

To gain a better understanding of how proteins function a process known as protein structure prediction (PSP) is carried out. However, experimental PSP methods, such as X-ray crystallography and Nuclear Magnetic Resonance (NMR), can be time-consuming and inaccurate. This has given rise to numerous computational PSP approaches to try and elicit a proteins three-dimensional conformation. A popular PSP search strategy is Genetic Algorithms (GA). GAs allow for a generic search approach, which can provide a generic improvement to alleviate the need to redefine the search strategies for separate sequences. Though GAs working principles are remarkable, a serious problem that is inherent in the GA search process is the growth of twins or identical chromosomes. Therefore, enhanced twin removal strategies are crucial for any GA search solving hard-optimisation problems like PSP. In this paper we explain our high-resolution GA feature-based resampling PSP approach and propose a twin removal strategy to ...
Tetracycline-responsive transcriptional activator driven by the liver-specific mouse major urinary protein promoter (MUP-tTA).. The E. Coli tetracycline operon regulatory system was used to generate a liver-specific transcription activation system that was inhibited by tetracycline. The transcription activator was a fused protein consisting of a tetracycline repressor gene (tetR) that was only active in the presence of tetracycline and a herpes simplex virus protein (VP-16) transcription activating domain (Tet-Off). Transcription was induced only in the absence of tetracycline (Tet-Off). A liver-specific promoter such as the mouse major urinary protein (MUP) promoter determined that the tetracycline-regulated transcriptional activator (tTA) would be expressed specifically in liver. To study the effect of the transcription activator on a target gene (for example, beta-galactosidase, LacZ) specifically in liver, MUP-tTA mice would be mated with transgenic mice in which the TAg Target gene was ...
Computational protein structure prediction has made great progress in the last three decades [1, 2]. Protein inter-residue contact prediction is one of the problems being actively studied in the structure prediction community. Recent CASP (Critical Assessment of Techniques for Protein Structure Prediction) [3-7] events have demonstrated that a few true contacts, extracted from template-based models, can provide very important information for protein structure refinement, especially on targets without good templates in PDB [8]. For example, Misura et al. [9] have revised the widely-used ab initio folding program, Rosetta [10], by incorporating inter-residue contact information as a component of Rosettas energy function, and shown that the revised Rosetta exhibits not only a better computational efficiency, but also a better prediction accuracy. For some test proteins, the models built by this revised Rosetta are more accurate than their template-based counterparts, which is rarely seen before ...

Protein three-dimensional structure prediction directly from amino acid sequence is an important issue in bioinformatics. An intermediate approach to this problem is to predict the so-called one-dimensional structural properties of proteins. The solvent accessibility or accessible surface area (ASA) of an amino acid residue in a protein structure is one such property and the knowledge of this property can significantly enhance the overall structure and function prediction of proteins [1, 2]. Given an amino acid sequence, the goal of such prediction is to estimate the ASA of each residue making use of previously observed ASA values taken from known protein structures. The knowledge from previously observed structures is modeled using machine learning and other methods [3-16]. Various methods of predicting ASA from sequence or sequence-derived evolutionary information have been developed such as neural networks [8-12], Bayesian analysis [13], information theory [14, 15], multiple linear ...

Understanding the link between protein structure and protein function is a fundamental problem that underlies diverse application areas including drug target identification, protein function prediction, and structure-based evolutionary analysis. The specific few amino acids that mediate the drug-binding affinity of targeted binding sites are an example of a substructure within a protein. The catalytic substructures of enzymatic proteins are intrinsically linked to enzyme function [1-4], and establishing a mechanistic understanding of how specific structural features affect protein function is a central problem in structural genomics [5]. The analysis of the physico-chemical properties of the few amino acids constituting these substructures, common to families of functionally related proteins, can provide direct insight to the structural features that dictate a particular enzymatic function [2]. For example, the family of serine proteases is a well-established case of a common functional ...

To determine the effect of GenotropinTM on whole body protein turnover (WBPT), IGF-1 levels and cytokines. Utilizing the stable isotope 1-[13C] leucine, we will measure WBPT. Measurements of WBPT will be correlated with LBM and changes in height and weight velocity. This data will be compared to that from age matched normal children (archival data maintained by the PI). We will measure IGF-1 and the cytokines TNF-α, IL-6 and IL-10 at baseline and very six months. These measures will be correlated with height and weight velocity and IGF-1 levels. Cytokine levels will also be correlated with protein catabolism. This specific aim tests the hypothesis that chronically ill children have increased catabolism, caused by high levels of circulating cytokines and low levels of IGF-1, and that these abnormalities improve with GenotropinTM ...

Protein domain superfamilies in CATH-Gene3D have been subclassified into functional families (or FunFams), which are groups of protein sequences and structures with a high probability of sharing the same function(s). Therefore, the functionally important residues in a family are also expected to be highly conserved.. Information on conserved positions in CATH-Gene3D FunFam alignments is shown through the Alignment tab of the FunFam webpages. Conservation scores have been calculated using Scorecons and columns in the alignment are coloured using a rainbow colour scheme, where the highly conserved residues are shown in red through to positions that are not conserved at all, shown in blue. The conservation scores are also mapped onto a representative protein domain structure.. To investigate putative conserved sites for your protein sequence, run a sequence search against the FunFams and click on the FunFam match Alignment page.. ...
Abstract: Despite impressive successes in protein design, designing a well-folded protein of more 100 amino acids de novo remains a formidable challenge. Exploiting the promising biophysical features of the artificial protein Octarellin V, we improved this protein by directed evolution, thus creating a more stable and soluble protein: Octarellin V.1. Next, we obtained crystals of Octarellin V.1 in complex with crystallization chaperons and determined the tertiary structure. The experimental structure of Octarellin V.1 differs from its in silico design: the (αβα) sandwich architecture bears some resemblance to a Rossman-like fold instead of the intended TIM-barrel fold. This surprising result gave us a unique and attractive opportunity to test the state of the art in protein structure prediction, using this artificial protein free of any natural selection. We tested 13 automated webservers for protein structure prediction and found none of them to predict the actual structure. More than 50% of ...
Specific binding between proteins plays a crucial role in molecular functions and biological processes. Protein binding interfaces and their atomic contacts are typically defined by simple criteria, such as distance-based definitions that only use some threshold of spatial distance in previous studies. These definitions neglect the nearby atomic organization of contact atoms, and thus detect predominant contacts which are interrupted by other atoms. It is questionable whether such kinds of interrupted contacts are as important as other contacts in protein binding. To tackle this challenge, we propose a new definition called beta (β) atomic contacts. Our definition, founded on the β-skeletons in computational geometry, requires that there is no other atom in the contact spheres defined by two contact atoms; this sphere is similar to the van der Waals spheres of atoms. The statistical analysis on a large dataset shows that β contacts are only a small fraction of conventional distance-based contacts. To

An intricate new three-dimensional protein structure is providing a detailed look into how brain cells communicate rapidly.. By visualizing how three neural proteins interact with one another, researchers have revealed how they help groups of brain cells release chemical messages at the same time.. The work describes a surprising new cooperation among the three proteins, and could offer insight into other processes where cells secrete molecules, including insulin and airway mucus.. When a group of neurons receives an electrical signal, the cells release chemicals called neurotransmitters nearly instantaneously - within less than one thousandth of a second. Neurons hold neurotransmitters in bubble-like structures called synaptic vesicles. These structures rest inside the end of long, thin projections that point toward neighboring cells. To free neurotransmitters from their bubbles, neurons must fuse vesicle membranes with the outer membrane of the projections. This opens the bubbles and dumps ...
Since the structure of proteins is more conserved than the sequence, the identification of conserved three-dimensional (3D) patterns among a set of proteins, can be important for protein function prediction, protein clustering, drug discovery and the establishment of evolutionary relationships. Thus, several computational applications to identify, describe and compare 3D patterns (or motifs) have been developed. Often, these tools consider a 3D pattern as that described by the residues surrounding co-crystallized/docked ligands available from X-ray crystal structures or homology models. Nevertheless, many of the protein structures stored in public databases do not provide information about the location and characteristics of ligand binding sites and/or other important 3D patterns such as allosteric sites, enzyme-cofactor interaction motifs, etc. This makes necessary the development of new ligand-independent methods to search and compare 3D patterns in all available protein structures. Here we introduce

Profacgen, a US-based biotech company, has added one additional molecular modeling service, protein structure modeling, to its existing custom protein services.. The three-dimensional structure of a protein provides essential information about its biological function and facilitates the design of therapeutic drugs that specifically bind to the protein target. Recent years have witnessed a tremendous increase in the number of experimentally determined protein structures. It is, however, still generally tedious and time-consuming to solve protein structures with experimental approaches. Therefore, computational approaches represent an alternative and supplement to experimental methods to obtain three-dimensional structure of a protein.. By taking advantages of computational modeling methods, Profacgen is able to predict the three-dimensional structure of proteins of its customers interest. Over the years, Profacgen has accumulated abundant experience with the modeling of various kinds of ...

How protein structure is established is a fascinating question and a field that is actively studied by prominent labs around the world. Protein folding is the process of a chain of amino acids curling into its final shape, and how this process occurs is complex and not completely understood. In general proteins fold depending on their environment (exposed to water or not, for example) and with the help of other proteins, called chaperones. Protein chaperones help to establish a proteins structure as well as maintain it during times of stress. Further, modifications on proteins can change their structures, such as when p53, a protein that is involved in regulating many processes within the cell, is phosphorylated - its structure and, consequently, its function is altered slightly ...

One such interaction, an anion-p pair, in which the positively charged edge of an aromatic ring interacts with an anion, forming a favorable anion-quadrupole interaction, has been previously proposed [Jackson, M.

Using this data, we can trace how viral proteins change over time in response to immune selection and drug treatment. We complement the sequence data with theoretical modeling, as well as with data on protein function and measurements of viral fitness.

Protein-ligand binding site prediction from a 3D protein structure plays a pivotal role in rational drug design and can be helpful in drug side-effects prediction or elucidation of protein function. Embedded within the binding site detection problem is the problem of pocket ranking - how to score and sort candidate pockets so that the best scored predictions correspond to true ligand binding sites. Although there exist multiple pocket detection algorithms, they mostly employ a fairly simple ranking function leading to sub-optimal prediction results. We have developed a new pocket scoring approach (named PRANK) that prioritizes putative pockets according to their probability to bind a ligand. The method first carefully selects pocket points and labels them by physico-chemical characteristics of their local neighborhood. Random Forests classifier is subsequently applied to assign a ligandability score to each of the selected pocket point. The ligandability scores are finally merged into the resulting

Affiliation:Department of Life Science, Xian University of Arts and Science, Xian 710065, China.. Keywords:Bioinformatics, prediction, protein subcellular localization, localizome, proteomics, database. Abstract: Protein subcellular localization is one of the key characteristic to understand its biological function. Proteins are transported to specific organelles and suborganelles after they are synthesized. They take part in cell activity and function efficiently when correctly localized. Inaccurate subcellular localization will have great impact on cellular function. Prediction of protein subcellular localization is one of the important areas in protein function research. Now it becomes the hot issue in bioinformatics. In this review paper, the recent progress on bioinformatics research of protein subcellular localization and its prospect ...
Background: Although suicide is a leading cause of death in the United States and represents a significant public health threat, little is known about the neurobiological or molecular factors that contribute to its pathophysiology. A number of studies now indicate that lithium has considerable efficacy in the prevention of suicide in patients with affective disorders, and accumulating evidence indicates that protein kinase C (PKC) and its substrates, in particular the myristoylated alanine-rich C kinase substrate (MARCKS), are primary targets of chronic lithium treatment. We therefore hypothesized that a dysregulation in MARCKS expression in key brain regions could contribute to the pathophysiology associated with suicide. To address this, we examined MARCKS, as well as the closely related MARCKS-related protein (MRP), mRNA expression in the hippocampus and dorsolateral prefrontal cortex of suicide victims and normal controls. Method: MARCKS and MRP mRNA expression was assessed by quantitative ...

Idiopathic pulmonary fibrosis is a progressive, fatal disease with limited treatment options. Protease-mediated transforming growth factor-β (TGF-β) activation has been proposed as a pathogenic mechanism of lung fibrosis. Protease activity in the lung is tightly regulated by protease inhibitors, particularly secretory leukocyte protease inhibitor (SLPI). The bleomycin model of lung fibrosis was used to determine the effect of increased protease activity in the lungs of Slpi− / − mice following injury. Slpi− / −, and wild-type, mice received oropharyngeal administration of bleomycin (30 IU) and the development of pulmonary fibrosis was assessed. Pro and active forms of matrix metalloproteinase (MMP)-2 and MMP-9 were measured. Lung fibrosis was determined by collagen subtype-specific gene expression, hydroxyproline concentration, and histological assessment. Alveolar TGF-β activation was measured using bronchoalveolar lavage cell pSmad2 levels and global TGF-β activity was assessed by ...
The aim of this study was to examine executive functioning in adolescents and adults with Cornelia de Lange syndrome (CdLS) to identify a syndrome and age-related profile of cognitive impairment. Participants were 24 individuals with CdLS aged 13-42 years (M = 22; SD = 8.98), and a comparable contrast group of 21 individuals with Down syndrome (DS) aged 15-33 years (M = 24; SD = 5.82). Measures were selected to test verbal and visual fluency, inhibition, perseverance/flexibility, and working memory and comprised both questionnaire and performance tests. Individuals with CdLS showed significantly greater impairment on tasks requiring flexibility and inhibition (rule switch) and on forwards span capacity. These impairments were also reported in the parent/carer-rated questionnaire measures. Backwards Digit Span was significantly negatively correlated with chronological age in CdLS, indicating increased deficits with age. This was not identified in individuals with DS. The relative deficits in executive
Background: Cornelia de Lange syndrome (CdLS) is a multisystem disorder with distinctive facial appearance, intellectual disability and growth failure as prominent features. Most individuals with typical CdLS have de novo heterozygous loss-of-function mutations in NIPBL with mosaic individuals representing a significant proportion. Mutations in other cohesin components, SMC1A, SMC3, HDAC8 and RAD21 cause less typical CdLS. Methods: We screened 163 affected individuals for coding region mutations in the known genes, 90 for genomic rearrangements, 19 for deep intronic variants in NIPBL and 5 had whole-exome sequencing. Results: Pathogenic mutations [including mosaic changes] were identified in: NIPBL 46 [3] (28.2%); SMC1A 5 [1] (3.1%); SMC3 5 [1] (3.1%); HDAC8 6 [0] (3.6%) and RAD21 1 [0] (0.6%). One individual had a de novo 1.3 Mb deletion of 1p36.3. Another had a 520 kb duplication of 12q13.13 encompassing ESPL1, encoding separase, an enzyme that cleaves the cohesin ring. Three de novo mutations were

  • Proteins perform a vast array of functions within organisms , including catalysing metabolic reactions , DNA replication , responding to stimuli , providing structure to cells , and organisms , and transporting molecules from one location to another. (
  • Those proteins bind small molecules and transport them to other locations in the cell or organism. (
  • For synthesis of protein, a succession of tRNA molecules charged with appropriate amino acids have to be brought together with an mRNA molecule and matched up by base-pairing through their anti-codons with each of its successive codons. (
  • This molecular juggernaut latches onto the end of an mRNA molecule and then trundles along it, capturing loaded tRNA molecules and stitching together the amino acids they carry to form a new protein chain. (
  • A tiny bundle of amino acids, every protein is dappled with furrows and compartments into which other proteins and molecules fit like keys into a tumbler. (
  • 2. Cells build large, complicated molecules, such as proteins. (
  • Labelling molecules by fast oxidation allows mass spectrometry to study protein folding at submillisecond time resolution. (
  • Cold denaturation occurs at low temperatures when water molecules bind to hydrophobic amino acids that are normally buried inside proteins. (
  • As the protein reshapes, amino acid residues in its vicinity move toward the inside of the cell, being replaced by water molecules that pass protons to amino acid residues in the cell's exterior. (
  • Activating the light-emitting molecules with a pulse of blue light from an external laser successfully coaxed laser light from the proteins. (
  • For example, the shell that protects the fluorescent protein molecules may also prevent it from being powered by an electrical supply like a battery, instead of another laser, he says. (
  • In a globular protein, the amino acid chain twists and folds in a manner that enhances the protein's solubility in water by placing polar groups of atoms at the protein's surface (where they can participate in attractive interactions with water molecules). (
  • This twisting and folding that determine the overall shape of a protein molecule (its tertiary structure) are due largely to the very complex interplay of intramolecular forces that exists among different groups of atoms within the molecule, and to intermolecular forces acting between groups of atoms on the protein and molecules in the protein's immediate surroundings. (
  • A protein's polar side chains tend to exert strong attractive forces toward other polar groups of atoms within the protein molecule, or toward polar molecules in the protein's surroundings. (
  • The aqueous solubility of globular proteins allows them to exist in biological fluids as individual molecules or in small clusters and to accomplish a wide range of critical biological functions, for example, the enzymatic catalysis of chemical reactions. (
  • They are also known as transporter proteins or carrier molecules, among other names. (
  • There are multiple types of transport proteins that move molecules with different functions in the cell, including water transporter proteins, channel proteins and ATP-powered pumps. (
  • Transport proteins are essential to the function of living beings, and very few molecules are able to cross between membranes without the aid of a protein. (
  • Amino acids Your body uses the protein you eat to make lots of specialized protein molecules that have specific jobs.For instance your body uses protein to make hemoglobin. (
  • Proteins are large molecules made up of long chains of amino acid subunits. (
  • Learning this type of information is important because the sequence of a protein determines its three-dimensional structure, and both of these aspects of a protein help determine how it interacts with other molecules. (
  • Digestion takes place via enzyme reactions that break up food into its constituent molecules: protein, fat, and carbohydrates. (
  • Throughout my scientific life I have been fascinated by the beautiful and complex structures of biology, especially those formed by proteins, and by the ability to see these molecules through the lens provided by crystals," Professor Baker says. (
  • During a research retreat in 1998 at a scenic resort on Semiahmoo Bay in northwest Washington, Deshaies paused in front of a poster by Crews to listen to him talk about using small molecules to link two proteins together. (
  • Proteins are polymer s whose molecules are made from many amino acid molecules linked together. (
  • In future, it might be possible to test whether individual molecules display memory, or whether proteins with an identical chemical structure might behave differently over long periods of time. (
  • Scientists have developed specialized proteins that can interfere with cancer's growth strategy at a molecular level. (
  • This type of molecular mechanistic studies can be useful to improve the shelf-life of protein drug products and understand protein aggregation-related disease mechanisms. (
  • The combination of all these atomic forces makes each protein a staggering molecular puzzle. (
  • Proteins are an enormous molecular achievement: chains of amino acids that fold spontaneously into a precise conformation, time after time, optimized by evolution for their particular function. (
  • The molecular weight of a protein is equal to the addition of the molecular weights of the amino acids constituting the protein. (
  • Some proteins are of relatively small molecular size, such as insulin, with a molecular weight of about 5,700 daltons. (
