TY - JOUR. T1 - Effect of ethanol on the synthesis and secretion of hepatic secretory glycoproteins and albumin. AU - Tuma, D. J.. AU - Jennett, R. B.. AU - Sorrell, Michael Floyd. PY - 1981/1/1. Y1 - 1981/1/1. N2 - The effects of ethanol on the synthesis and secretion of serum glycoproteins and albumin, a nonglycosylated protein, were studied in rat liver slices. Serum glycoproteins and albumin were determined by immunoprecipitation from either the incubation medium or from the washed slices. When ethanol (10 mM) was present in the incubation medium, [14C]glucosamine incorporation in secretory glycoproteins was decreased. This inhibitory effect was, however, much greater in the secretory proteins released into the medium than in those retained in the liver slices. Similar inhibitions by ethanol were also observed when leucine or valine were used as a label for either total export proteins or albumin. Since ethanol impaired protein synthesis, an inhibitor of protein synthesis, cycloheximide, was ...

Stanniocalcin-2 (STC2), the paralog of STC1, has been suggested as a novel target of oxidative stress response to protect cells from apoptosis. The expression of STC2 has been reported to be highly correlated with human cancer development. In this study, we reported that STC2 is a HIF-1 target gene and is involved in the regulation of cell proliferation. STC2 was shown to be up-regulated in different breast and ovarian cancer cells, following exposure to hypoxia. Using ovarian cancer cells (SKOV3), the underlying mechanism of HIF-1 mediated STC2 gene transactivation was characterized. Hypoxia-induced STC2 expression was found to be HIF-1α dependent and required the recruitment of p300 and HDAC7. Using STC2 promoter deletion constructs and site-directed mutagenesis, two authentic consensus HIF-1 binding sites were identified. Under hypoxic condition, the silencing of STC2 reduced while the overexpression of STC2 increased the levels of phosphorylated retinoblastoma and cyclin D in both SKOV3 and MCF7
The ability of PS to enhance the inhibition of FXa by plasma TFPI and by recombinant TFPIα produced in Escherichia coli was originally demonstrated by Hackeng et al.3 Subsequent studies have investigated the interaction of PS and TFPIα in plasma, finding that patients with PS deficiency have decreased plasma TFPIα, that immunodepletion of PS depletes plasma TFPIα as well, and that plasma TFPIα correlates with free PS, rather than with C4bp-bound PS.8 Thus, it seems that there is a physiologically relevant PS-TFPI anticoagulant system functioning in vivo, yet much remains unclear. The majority of intravascular TFPI is TFPIβ on the endothelium, which does not have the PS-binding K3 domain.24,25 In addition, the repercussions of FXa inhibition by PS-TFPIα are not apparent, as TFPIα is a poor inhibitor of thrombin production by the prothrombinase complex assembled with FXa and thrombin-activated FVa, and PS does not enhance this inhibitory function to physiologically relevant rates (Figure ...
Methods and Results-Concomitant with the angiogenic and proliferative responses, hVEGF-DΔNΔC enhanced the phosphorylation of VEGF receptor-2, Akt, and endothelial nitric oxide synthase. Gene arrays, quantitative reverse transcription-polymerase chain reaction, and Western blot revealed increases in VEGF-A, stanniocalcin-1 (STC1), and neuropilin (NRP) 2 expression by hVEGF-DΔNΔC stimulation, whereas induction with hVEGF-A165 altered the expression of STC1 and NRP1, another coreceptor for VEGFs. The effects of hVEGF-DΔNΔC were seen only under high-serum conditions, whereas for hVEGF-A165, the strongest response was observed under low-serum conditions. The hVEGF-DΔNΔC-induced upregulation of STC1 and NRP2 was also evident in vivo in mouse skeletal muscle treated with hVEGF-DΔNΔC by adenoviral gene delivery. The importance of NRP2 in hVEGF-DΔNΔC signaling was further studied with NRP2 small interfering RNA and NRP antagonist, which were able to block hVEGF-DΔNΔC-induced survival of ...

We used domain-selective biotinylation/125I-streptavidin blotting (Sargiacomo, M., M. P. Lisanti, L. Graeve, A. Le Bivic, and E. Rodriguez-Boulan. 1989 J. Membr. Biol. 107:277-286), in combination with lectin precipitation, to analyze the apical and basolateral glycoprotein composition of Madin-Darby canine kidney (MDCK) cells and to explore the role of glycosylation in the targeting of membrane glycoproteins. All six lectins used recognized both apical and basolateral glycoproteins, indicating that none of the sugar moieties detected were characteristic of the particular epithelial cell surface. Pulse-chase experiments coupled with domain-selective glycoprotein recovery were designed to detect the initial appearance of newly synthesized glycoproteins at the apical or basolateral cell surface. After a short pulse with a radioactive precursor, glycoproteins reaching each surface were biotinylated, extracted, and recovered via precipitation with immobilized streptavidin. Several basolateral ...
Summary The glycoproteins of cells infected with herpes simplex virus 1 or 2 (HSV-1 or HSV-2) were solubilized with non-ionic detergent NP-40 and electrophoresed in acrylamide gels. At least 12 bands containing virus glycoproteins were formed. The HSV-1 glycoproteins correspond in electrophoretic mobility to structural proteins in the HSV virions and to the virus proteins in plasma membranes of infected cells. All virus glycoproteins were bound to immunoadsorbent columns made by cross-linking either homologous or heterologous antibody. Immunoadsorbent columns readily discriminated between host and virus glycoproteins. The differentiation between HSV-1 and HSV-2 glycoproteins varied; the degree of specificity of the immunoadsorbent gels was related to the specificity exhibited by the antisera in neutralization tests. All immunoadsorbent antibody gels tested bound homologous glycoproteins in proportions similar to those in the input extract. Immunoadsorbent antibody gels of high specificity bound

Stanniocalcins (STCs) represent small glycoprotein hormones, found in all vertebrates, which have been functionally implicated in Calcium homeostasis. However, recent data from mammalian systems indicated that they may be also involved in embryogenesis, tumorigenesis and in the context of the latter especially in angiogenesis. Human STC1 is a 247 amino acids protein with a predicted molecular mass of 27 kDa, but preliminary data suggested its di- or multimerization. The latter in conjunction with alternative splicing and/or post-translational modification gives rise to forms described as STC50 and big STC, which molecular weights range from 56 to 135 kDa. In this study we performed a biochemical and structural analysis of STC1 with the aim of obtaining low resolution structural information about the human STC1, since structural information in this protein family is scarce. We expressed STC1 in both E. coli and insect cells using the baculo virus system with a C-terminal 6 × His fusion tag. From the

It was found previously that transection of one branch of the bifurcate axon of a giant serotonergic neuron of Aplysia causes a proportionate decrease in the export of transmitter storage vesicles from the cell body, despite the ability of the remaining branch to transport all of the vesicles normally exported (Aletta and Goldberg, 1982). We report here evidence that this down-regulation is achieved by a decrease in the production of vesicles, rather than a slowing of the processing of vesicles for export from the cell body. Counts of serotonergic vesicles in the cell body show that the size of the somal pool of vesicles is not increased at a time when their rate of export has been halved. Also, transection of one or both branches of the axon decreases the amount of 3H-fucose incorporated during a short period into a putative vesicle membrane glycoprotein but not into other glycoproteins. The results indicate that axotomy should be a useful technique for studying the mechanism of regulation of ...

The quantity of enzymes recommended in the protocols is sufficient to deglycosylate approximately 100 μg of an average glycoprotein in the time given. PNGase F cleavage is generally the rate limiting reaction due to the slow removal of some sterically hindered N- linked residues, even when the glycoprotein is denatured. Since all of the enzymes retain activity under reaction conditions for several days, a much larger quantity of glycoprotein may be deglycosylated if incubation is extended. Conversely, there is no need to use the recommended amounts of enzymes if quantities much less than 100 μg of glycoprotein are being cleaved. The enzymes can be diluted into 1X Reaction Buffer 7. They will remain stable in diluted form at 4°C.. Bovine Fetuin Control Protein ...
Each one of these peptides can result in a different VPL motor that can have different properties such as different weight, volume, range of motion, force and speed capabilities. However, the principle of actuation is the same. Studies have shown that the common characteristic in these viruses is the structure of a portion of the surface protein (envelope glycoprotein) and the mode of infection. The envelope glycoproteins of these viruses can be divided into two subunits, which are a result of proteolytic cleavage of a common precursor protein. The two subunits have different functions. For example, in the case of HIV 1 the precursor glycoprotein is gp160, which is proteolytically cleaved into gp120 and gp41 subunits. The gp120 is the surface subunit and the gp41 is the transmembrane (TM) subunit. The surface subunit serves to recognize the cell to be infected when it comes in the vicinity of the virus with the help of receptors located on the cell surface. The gp41 mediates membrane fusion ...

There is no such thing as *the* method to purify proteins, each protein is different and needs its own combination of methods. Now since you are talking about glycoproteins I presume that you are dealing with a transmembrane protein. To isolate those, you homogenise your cells and isolate the compartment where your protein lives (ER, Golgi, PM, lysosome...). There are standard methods for that, check e.g. Meth. Enzymol. Then you solubilise the membranes with a suitable detergent. There are hundreds of detergents out there, dozens are in common use for membrane protein isolation and may be one or two will solubilise your particular protein without destroying its activity.

TY - JOUR. T1 - Herpes simplex virus glycoproteins gD and gE/gI serve essential but redundant functions during acquisition of the virion envelope in the cytoplasm. AU - Farnsworth, Aaron. AU - Goldsmith, Kimberly. AU - Johnson, David C.. PY - 2003/8/1. Y1 - 2003/8/1. N2 - The late stages of assembly of herpes simplex virus (HSV) and other herpesviruses are not well understood. Acquisition of the final virion envelope apparently involves interactions between viral nucleocapsids coated with tegument proteins and the cytoplasmic domains of membrane glycoproteins. This promotes budding of virus particles into cytoplasmic vesicles derived from the trans-Golgi network or endosomes. The identities of viral membrane glycoproteins and tegument proteins involved in these processes are not well known. Here, we report that HSV mutants lacking two viral glycoproteins, gD and gE, accumulated large numbers of unenveloped nucleocapsids in the cytoplasm. These aggregated capsids were immersed in an ...
SDS-PAGE studies of EBO virion glycoproteins (Fig. 1 and 3A) and N-terminal sequencing have provided definitive evidence that GP is cleaved (from GP0 form) into two molecules, GP1 and GP2. Cleavage of the structural GP gene product of EBO virus was expected for the N-terminal signal sequence and occurs at the predicted site. Cleavage of GP by furin had been predicted from the RRTRR sequence, but identification of the C-terminal fragment in virions was complicated by its comigration with VP24 in SDS-PAGE. However, prior studies detected GP2 in EBO-infected tissue culture fluids (17, 21), and it was suggested that this uncharacterized glycoprotein might be derived from a cleavage event involving GP. Indirect evidence for furin cleavage of EBO virus GP was recently demonstrated through the use of specific inhibitors of furin activity (21).. When GP sequences of all known EBO viruses are aligned, one finds that the furin cleavage site is conserved but differs slightly from one EBO species to ...

Glycoproteins are a very large and biologically relevant class of proteins that comprise more than 50 % of proteins in the human body. The glycosylation present on proteins, specifically N-linked glycosylation has been shown to be important for a variety of processes including protein folding, protein stability, and cell-cell interactions. Many glycoproteins are currently being considered as therapeutic drug targets. Glycosylation on proteins has also been shown to be altered with the onset of diseases, such as cancer, which has opened up the field of glycoproteomics, which aims to detect glycosylation changes for earlier detection of disease states. Mass spectrometry is a versatile technique that is frequently utilized for the analysis of glycoproteins, and it is particularly useful in the detection of glycosylation present on proteins. Most glycoproteins are prepared for mass spectrometric analysis by performing a protease digestion, followed by either a separation by HPLC or some other ...

The objective of this investigation was primarily to establish that the apparent increase in serum fucose levels in patients with malignant tumors is real and to obtain data as to its source. Carbohydrate residues (L-fucose, D-mannose, D-galactose) were estimated by borate ion-exchange chromatography after mild acid hydrolysis of serum proteins. Data are presented which confirm reported increases in levels of serum fucose in certain malignancies and indicate that these increases may be attributed to quantitative alterations in specific serum glycoproteins observed in the glycoprotein profile associated with cancer. Values for serum fucose levels in pathological and nonpathological sera obtained by various analytical methods are presented and discussed. (Author)

Laminin is a large molecular weight glycoprotein present only in basement membranes in almost every animal tissue. Each laminin is a heterotrimer assembled from α, β and γ chain subunits, secreted and incorporated into cell-associated extracellular matrices. The laminins can self-assemble, bind to other matrix macromolecules, and have unique and shared cell interactions mediated by integrins, dystroglycan, and other receptors. Through these interactions, laminins critically contribute to cell differentiation, shape and movement, maintenance of tissue phenotypes, and promotion of tissue survival [1,2]. The different laminin chains share a 600-residue domain I/II which oligomerizes into a rod-like coiled-coil structure forming the long arm of laminins. The N-terminal short arms consist of rod-like elements (domain III and V) formed by tandem arrays of laminin-type EGF modules (see ,PDOC00961,) and several globular domains: domains IV and domain VI (laminin N-terminal) (see ,PDOC51117,).

INTRODUCTION. In 1999 the Nobel Prize in Physiology or Medicine was awarded to Gunter Blobel for the discovery that proteins have intrinsic signals that govern their transport and localisation in the cell. It was based on this research into how cells use these signals that the functions of glycoproteins were discovered.. Glycoproteins are molecules that have a sugars and protein bonded together. The sugar chains of glycoproteins play a role in determining their destination in the cell or body. The bonding of sugars to proteins to form glycoproteins significantly alters the properties of these proteins.. There are eight sugars that predominantly bond with proteins to form glycoproteins, these are: xylose, galactose, glucose, mannose, fucose, N-acetylgalactosamine, N-acetylglucosamine and N-acetylneuraminic acid.. WHAT ARE THE FUNCTIONS OF GLYCOPROTEINS?. Glycans contain biologic information and are the specific sequence of sugars in a glycoprotein that determine its recognition and interaction ...
Sodium/potassium-transporting ATPase subunit beta-1 is an enzyme that in humans is encoded by the ATP1B1 gene.[1] The protein encoded by this gene belongs to the family of Na+/K+ and H+/K+ ATPases beta chain proteins, and to the subfamily of Na+/K+-ATPases. Na+/K+-ATPase is an integral membrane protein responsible for establishing and maintaining the electrochemical gradients of Na and K ions across the plasma membrane. These gradients are essential for osmoregulation, for sodium-coupled transport of a variety of organic and inorganic molecules, and for electrical excitability of nerve and muscle. This enzyme is composed of two subunits, a large catalytic subunit (alpha) and a smaller glycoprotein subunit (beta). The beta subunit regulates, through assembly of alpha/beta heterodimers, the number of sodium pumps transported to the plasma membrane. The glycoprotein subunit of Na+/K+-ATPase is encoded by multiple genes. This gene encodes a beta 1 subunit. Alternatively spliced transcript variants ...

Cross-suppression of AREG/EREG expression may explain the tight co-expression of AREG and EREG, as well as their tendency to be more highly expressed than other EGFR ligands to determine Ctx efficacy. The positive selection for Ctx-resistant tumour cells exhibiting AREG/EREG cross-suppression may ha …

Methods for making glycoproteins, both in vitro and in vivo, are provided. One method involves incorporating an unnatural amino acid into a protein and attaching one or more saccharide moieties to the unnatural amino acid. Another method involves incorporating an unnatural amino acid that includes a saccharide moiety into a protein. Proteins made by both methods can be further modified with additional sugars.

In structural biology, a protomer is the structural unit of an oligomeric protein. It is the smallest unit composed of at least two different protein chains that form a larger hetero-oligomer by association of two or more copies of this unit. The term was introduced by Chetverin [1] to make nomenclature in the Na/K-ATPase enzyme unambiguous. This enzyme is composed of two subunits, a large catalytic subunit, alpha and a smaller glycoprotein subunit, beta (plus a proteolipid, called γ-subunit). At the time it was unclear how many of each work together. In addition, when people spoke of a dimer, did they refer to αβ or to (αβ)2? Chetverin suggested to call αβ a protomer and (αβ)2 a diprotomer. Protomers usually arrange in cyclic symmetry to form closed point group symmetries. In chemistry, a so-called protomer is a molecule which displays tautomerism due to position of a proton.[2][3] ...
Our research focuses on the chemical synthesis and the biological. investigation of signaling molecules for cells. We are developing. and improving syntheses for three classes of biomolecules:. oligosaccharides, peptides and glycoproteins. Oligosaccharides. are playing a major role in cell-surface binding events, protein. stability and immunology and can be considered an emerging field. in bioscience. Oligosaccharides have potential as diagnostic markers. and vaccines and can be synthesized by chemical and enzymatic. methods. Proteins and glycoproteins are of high interest for biotechnology. since their recombinant production provides many pharmaceutical. products such as cellular growth factors or monoclonal antibodies.. ...

Scientists have developed a system which can pinpoint potential biomarkers of early forms of cancer, by looking at structures of specific sugar molecules which are attached either to proteins of cancerous cells or to proteins involved in the host response. The availability of such cancer biomarkers could also allow disease progression and response to therapy to be monitored more easily and accurately than is currently possible.
