Binding is measured by changes in the refractive index. The technique is used to study biomolecular interactions, such as antigen-antibody binding.

Cryo-electron microscopy structure of an SH3 amyloid fibril and model of the molecular packing. (1/3051)

Amyloid fibrils are assemblies of misfolded proteins and are associated with pathological conditions such as Alzheimer's disease and the spongiform encephalopathies. In the amyloid diseases, a diverse group of normally soluble proteins self-assemble to form insoluble fibrils. X-ray fibre diffraction studies have shown that the protofilament cores of fibrils formed from the various proteins all contain a cross-beta-scaffold, with beta-strands perpendicular and beta-sheets parallel to the fibre axis. We have determined the threedimensional structure of an amyloid fibril, formed by the SH3 domain of phosphatidylinositol-3'-kinase, using cryo-electron microscopy and image processing at 25 A resolution. The structure is a double helix of two protofilament pairs wound around a hollow core, with a helical crossover repeat of approximately 600 A and an axial subunit repeat of approximately 27 A. The native SH3 domain is too compact to fit into the fibril density, and must unfold to adopt a longer, thinner shape in the amyloid form. The 20x40-A protofilaments can only accommodate one pair of flat beta-sheets stacked against each other, with very little inter-strand twist. We propose a model for the polypeptide packing as a basis for understanding the structure of amyloid fibrils in general.  (+info)

Socs1 binds to multiple signalling proteins and suppresses steel factor-dependent proliferation. (2/3051)

We have identified Socs1 as a downstream component of the Kit receptor tyrosine kinase signalling pathway. We show that the expression of Socs1 mRNA is rapidly increased in primary bone marrow-derived mast cells following exposure to Steel factor, and Socs1 inducibly binds to the Kit receptor tyrosine kinase via its Src homology 2 (SH2) domain. Previous studies have shown that Socs1 suppresses cytokine-mediated differentiation in M1 cells inhibiting Janus family kinases. In contrast, constitutive expression of Socs1 suppresses the mitogenic potential of Kit while maintaining Steel factor-dependent cell survival signals. Unlike Janus kinases, Socs1 does not inhibit the catalytic activity of the Kit tyrosine kinase. In order to define the mechanism by which Socs1-mediated suppression of Kit-dependent mitogenesis occurs, we demonstrate that Socs1 binds to the signalling proteins Grb-2 and the Rho-family guanine nucleotide exchange factors Vav. We show that Grb2 binds Socs1 via its SH3 domains to putative diproline determinants located in the N-terminus of Socs1, and Socs1 binds to the N-terminal regulatory region of Vav. These data suggest that Socs1 is an inducible switch which modulates proliferative signals in favour of cell survival signals and functions as an adaptor protein in receptor tyrosine kinase signalling pathways.  (+info)

Anopheles gambiae Ag-STAT, a new insect member of the STAT family, is activated in response to bacterial infection. (3/3051)

A new insect member of the STAT family of transcription factors (Ag-STAT) has been cloned from the human malaria vector Anopheles gambiae. The domain involved in DNA interaction and the SH2 domain are well conserved. Ag-STAT is most similar to Drosophila D-STAT and to vertebrate STATs 5 and 6, constituting a proposed ancient class A of the STAT family. The mRNA is expressed at all developmental stages, and the protein is present in hemocytes, pericardial cells, midgut, skeletal muscle and fat body cells. There is no evidence of transcriptional activation following bacterial challenge. However, bacterial challenge results in nuclear translocation of Ag-STAT protein in fat body cells and induction of DNA-binding activity that recognizes a STAT target site. In vitro treatment with pervanadate (vanadate and H2O2) translocates Ag-STAT to the nucleus in midgut epithelial cells. This is the first evidence of direct participation of the STAT pathway in immune responses in insects.  (+info)

DEF-1, a novel Src SH3 binding protein that promotes adipogenesis in fibroblastic cell lines. (4/3051)

The Src homology 3 (SH3) motif is found in numerous signal transduction proteins involved in cellular growth and differentiation. We have purified and cloned a novel protein, DEF-1 (differentiation-enhancing factor), from bovine brain by using a Src SH3 affinity column. Ectopic expression of DEF-1 in fibroblasts resulted in the differentiation of a significant fraction of the culture into adipocytes. This phenotype appears to be related to the induction of the transcription factor peroxisome proliferator-activated receptor gamma (PPARgamma), since DEF-1 NIH 3T3 cells demonstrated augmented levels of PPARgamma mRNA and, when treated with activating PPARgamma ligands, efficient induction of differentiation. Further evidence for a role for DEF-1 in adipogenesis was provided by heightened expression of DEF-1 mRNA in adipose tissue isolated from obese and diabetes mice compared to that in tissue isolated from wild-type mice. However, DEF-1 mRNA was detected in multiple tissues, suggesting that the signal transduction pathway(s) in which DEF-1 is involved is not limited to adipogenesis. These results suggest that DEF-1 is an important component of a signal transduction process that is involved in the differentiation of fibroblasts and possibly of other types of cells.  (+info)

Identification of a new Pyk2 target protein with Arf-GAP activity. (5/3051)

Protein tyrosine kinase Pyk2 is activated by a variety of G-protein-coupled receptors and by extracellular signals that elevate intracellular Ca2+ concentration. We have identified a new Pyk2 binding protein designated Pap. Pap is a multidomain protein composed of an N-terminal alpha-helical region with a coiled-coil motif, followed by a pleckstrin homology domain, an Arf-GAP domain, an ankyrin homology region, a proline-rich region, and a C-terminal SH3 domain. We demonstrate that Pap forms a stable complex with Pyk2 and that activation of Pyk2 leads to tyrosine phosphorylation of Pap in living cells. Immunofluorescence experiments demonstrate that Pap is localized in the Golgi apparatus and at the plasma membrane, where it is colocalized with Pyk2. In addition, in vitro recombinant Pap exhibits strong GTPase-activating protein (GAP) activity towards the small GTPases Arf1 and Arf5 and weak activity towards Arf6. Addition of recombinant Pap protein to Golgi preparations prevented Arf-dependent generation of post-Golgi vesicles in vitro. Moreover, overexpression of Pap in cultured cells reduced the constitutive secretion of a marker protein. We propose that Pap functions as a GAP for Arf and that Pyk2 may be involved in regulation of vesicular transport through its interaction with Pap.  (+info)

Granulocyte-macrophage colony-stimulating factor-activated signaling pathways in human neutrophils. Involvement of Jak2 in the stimulation of phosphatidylinositol 3-kinase. (6/3051)

Granulocyte-macrophage colony-stimulating factor (GM-CSF) regulates many of the biological activities of human neutrophils. The signaling pathways via which these effects are mediated are not fully understood. We have shown previously that GM-CSF treatment of human neutrophils activates the Janus kinase/signal transducers and activators of transcription (Jak/STAT) pathway and, more specifically, Jak2, STAT3, and STAT5B in neutrophils. GM-CSF also stimulates the activity of the phosphatidylinositol 3-kinase (PI3-kinase) in a tyrosine kinase-dependent manner. Here we report that pretreating the cells with a Jak2 inhibitor (AG-490) abolishes tyrosine phosphorylation of the p85 subunit of PI3-kinase induced by GM-CSF. Furthermore, p85 was found to associate with Jak2, but not with Lyn, in stimulated cells in situ and with its autophosphorylated form in vitro; however, Jak2 did not bind to either of the two Src homology 2 (SH2) domains of the p85 subunit of PI3-kinase. Although STAT5B bound to the carboxyl-terminal SH2 domain of p85, it was absent from the complex containing PI3-kinase and Jak2. These results suggest that stimulation of the activity of PI3-kinase induced by GM-CSF is mediated by Jak2 and that the association between Jak2 and p85 depends on an adaptor protein yet to be identified.  (+info)

C-terminal Src kinase associates with ligand-stimulated insulin-like growth factor-I receptor. (7/3051)

Increased expression of the insulin-like growth factor-I receptor (IGF-IR) protein-tyrosine kinase occurs in several kinds of cancer and induces neoplastic transformation in fibroblast cell lines. The transformed phenotype can be reversed by interfering with the function of the IGF-IR. The IGF-IR is required for transformation by a number of viral and cellular oncoproteins, including SV40 large T antigen, Ras, Raf, and Src. The IGF-IR is a substrate for Src in vitro and is phosphorylated in v-Src-transformed cells. We observed that the IGF-IR and IR associated with the C-terminal Src kinase (CSK) following ligand stimulation. We found that the SH2 domain of CSK binds to the tyrosine-phosphorylated form of IGF-IR and IR. We determined the tyrosine residues in the IGF-IR and in the IR responsible for this interaction. We also observed that fibroblasts stimulated with IGF-I or insulin showed a rapid and transient decrease in c-Src tyrosine kinase activity. The results suggest that c-Src and CSK are involved in IGF-IR and IR signaling and that the interaction of CSK with the IGF-IR may play a role in the decrease in c-Src activity following IGF-I stimulation.  (+info)

Identification of Grb4/Nckbeta, a src homology 2 and 3 domain-containing adapter protein having similar binding and biological properties to Nck. (8/3051)

Adapter proteins made up of Src homology (SH) domains mediate multiple cellular signaling events initiated by receptor protein tyrosine kinases. Here we report that Grb4 is an adapter protein closely related to but distinct from Nck that is made up of three SH3 domains and one SH2 domain. Northern analysis indicated that both genes are expressed in multiple tissues. Both Nck and Grb4 proteins could associate with receptor tyrosine kinases and the SH3-binding proteins PAK, Sos1, and PRK2, and they synergized with v-Abl and Sos to induce gene expression via the transcription factor Elk-1. Although neither protein was transforming on its own, both Nck and Grb4 cooperated with v-Abl to transform NIH 3T3 cells and influenced the morphology and anchorage-dependent growth of wild type Ras-transformed cells. Nck and Grb4 therefore appear to be functionally redundant.  (+info)

The MLL gene, the closest human homologue to the Drosophila trithorax gene, undergoes chromosomal translocation with a large number of different partner genes in both acute lymphoid and acute myeloid leukemias. We have identified a new partner gene, EEN, fused to MLL in a case of acute myeloid leukemia. The gene is located on chromosome 19p13, where two other MLL partner genes, ENL and ELL/MEN have also been identified. The deduced protein of 368 aa contains a central α-helical region and a C-terminal Src homology 3 (SH3) domain most similar to the C-terminal SH3 domain found in the Grb2/Sem-5/Drk family of genes. Sequence analysis of the fusion MLL/EEN transcript in our patient reveals that exon 6 of MLL is fused to the N- terminal end of EEN, a fusion that would create a chimeric protein that includes the major functional domain of EEN. EEN is expressed in a variety of tissue types and encodes a protein of approximately 46 kDa. The EEN protein is the human homologue of a member of a recently ...

Receptor tyrosine kinases (RTKs) control a host of biological functions by phosphorylating tyrosine residues of intracellular proteins upon extracellular ligand binding. The phosphotyrosines (p-Tyr) then recruit a subset of ∼100 Src homology 2 (SH2) domain-containing proteins to the cell membrane. The in vivo kinetics of this process are not well understood. Here we use total internal reflection (TIR) microscopy and single-molecule imaging to monitor interactions between SH2 modules and p-Tyr sites near the cell membrane. We found that the dwell time of SH2 modules within the TIR illumination field is significantly longer than predictions based on chemical dissociation rate constants, suggesting that SH2 modules quickly rebind to nearby p-Tyr sites after dissociation. We also found that, consistent with the rebinding model, the effective diffusion constant is negatively correlated with the respective dwell time for different SH2 domains and the dwell time is positively correlated with the local

Phospholipase C (PLC)-gamma is unique among the PLC enzymes because each PLC-gamma isozyme contains a split pleckstrin homology (PH) domain with an SH2SH2SH3 tandem repeat insertion (where SH indicates Src homology domain) in the middle of its sequence. Split PH domains exist in a number of other proteins that play crucial signaling roles. However, little is known about the structure and function of split PH domains. The C-terminal half of the PLC-gamma split PH domain has been implicated to interact directly with the TRPC3 calcium channel, thereby providing a direct coupling mechanism between PLC-gamma and agonist-induced calcium entry. However, this interaction has not been proved by direct biochemical or structural studies. Here we determined the three-dimensional structure of the split PH domain of PLC-gamma1, and we found that the split PH domain of the enzyme folds into a canonical PH domain fold with high thermostability. The SH2SH2SH3 insertion between the beta3 and beta4 strands does ...
In light of the Scansite prediction and these data, we tested the potential of these proteins to interact with an inactive mutant of caspase-8-to prevent apoptosis induction-in transfected cells. P85 strongly interacted with caspase-8 ( Fig. 2B). This interaction depended on the integrity of the Y380 site but was independent of another phosphorylation site, Y334, identified independently by proteomics ( 12). The interaction was also dependent on cotransfected, activated c-src (Y527F or Δ92-95) or c-fyn (Y531F), which were more effective than wild-type c-src or kinase-inactive c-src (K295M). The phosphorylation of caspase-8 by these src constructs correlated with the magnitude of the caspase-8-p85 interaction. Deletion of the COOH-terminal SH2 domain of p85 abolished the interaction ( Fig. 2C), implicating this SH2 domain in the caspase-8 interaction. Other candidates identified from the Panomics screen (Nck-2, c-fyn, SHP-2) interacted more weakly or independently of phosphorylation ...

oriented toward one of the stimulus sh, and the distance to this sh was set at 14, 16, 18, 22, and 28 cm. Following the light stimulus, test sh were again released and observed. Krause and Tegeder hypothesized that sh would approach the neighbor that they could reach in the shortest amount of time, even if that meant turning toward the second sh and approaching it. This hypothesis held true in the experiment, as test sh took time to turn and approach their nearer neighbor if it would take less time than swimming straight toward a farther sh. It should be noted that sh did not always turn toward the closer neighbor, but this behavior became more probable as distance increased (Figure 10). !In the nal experiment, the time-minimization hypothesis was tested using 5 free-swimming sh in a test pool. Fish were given time to acclimate and spread out before the light stimulus was introduced. Immediately following the stimulus, sh executed behavior known as a #C-start, a short-term predator evasion reex ...

SH2B adapter protein 3 (SH2B3), also known as lymphocyte adapter protein (LNK), is a protein that in humans is encoded by the SH2B3 gene on chromosome 12. SH2B adapter protein 3 is a protein that in humans is encoded by the SH2B3 gene on chromosome 12. It is ubiquitously expressed in many tissues and cell types. LNK functions as a regulator in signaling pathways relating to hematopoiesis, inflammation, and cell migration. As a result, it is involved in blood diseases, autoimmune disorders, and vascular disease. The SH2B3 gene also contains one of 27 SNPs associated with increased risk of coronary artery disease. The SH2B3 gene resides on chromosome 12 at the band 12q24 and contains 12 exons. This protein belongs to the Src homology 2-B (SH2B) adapter family. LNK contains 3 functional domains: a C-terminal Src homology 2 (SH2) domain, a pleckstrin homology (PH) domain, and a dimerization domain. The SH2 domain spans approximately 100 amino acid residues and binds phosphotyrosine-containing ...
DescriptionThe Crk family of adaptor proteins is ubiquitously expressed in most tissues and mediates the timely formation of protein complexes elicited by a variety of extracellular stimuli, including various growth and differentiation factors. This class of proteins lacks an apparent catalytic domain and may serve as adaptors, coupling different proteins of a signal transduction cascade. Crk adaptor proteins are made up of one modular Src homology 2 (SH2) and two Src homology 3 (SH3) domains. SH2 domains bind to phosphotyrosine (pTyr) containing sequence, while SH3 domain binds to proline rich motifs. The two SH3 domains are separated by long linker containing highly conserved proline reisdues. Although the role of SH2 and N-terminal SH3 (SH3N) domains of Crk has been generally delineated, the role of C-terminal SH3 (SH3C) domain remains entirely unknown. There is, however, increasing evidence that the SH3C domain along with the linker act as a regulatory element. Despite the fact that Crk has ...
Endocytosis is a fundamental process in signaling and membrane trafficking. The formation of vesicles at the plasma membrane is mediated by the G protein dynamin that catalyzes the final fission step, the actin cytoskeleton, and proteins that sense or induce membrane curvature. One such protein, the F-BAR domain-containing protein pacsin, contributes to this process and has been shown to induce a spectrum of membrane morphologies, including tubules and tube constrictions in vitro. Full-length pacsin isoform 1 (pacsin-1) has reduced activity compared to its isolated F-BAR domain, implicating an inhibitory role for its C-terminal Src homology 3 (SH3) domain. Here we show that the autoinhibitory, intramolecular interactions in pacsin-1 can be released upon binding to the entire proline-rich domain (PRD) of dynamin-1, resulting in potent membrane deformation activity that is distinct from the isolated F-BAR domain. Most strikingly, we observe the generation of small, homogenous vesicles with the activated

The structure and function of the nervous system is dependent on highly coordinated patterns of migrating neurons. This patterning in many neuronal tissues, including the cortex and retina, results in cell lamination that is essential for proper function of the tissue. Adaptor proteins CT10 regulator of kinase (CRK) and CRK-like are known to be important for proper migration of neurons in the developing cortex through their role in the Reelin signaling pathway. We use Danio rerio, or Zebrafish, as a model organism to study the role of Crk and Crkl in the developing retina. Previous data from our lab have demonstrated that deficiency of Crk and Crkl during development negatively impacts eye size and retinal lamination in Zebrafish. To study the mechanism responsible for this phenotype, we used immunohistochemistry to label proliferating cells in the retina of Crk-deficient, Crkl-deficient, and Crk- and Crkl-deficient embryos at various developmental stages. We hypothesized that Crk- and Crkl-deficient
Proteins encoding phosphotyrosine binding (PTB) domains function as adaptors or scaffolds to organize the signaling complexes involved in wide-ranging physiological processes including neural development, immunity, tissue homeostasis and cell growth. Due to structural differences, PTB domains are divided into three groups represented by phosphotyrosine-dependent IRS-like, phosphotyrosine-dependent Shc-like (see ,PDOC00907,), and phosphotyrosine-independent Dab-like PTBs (see ,PDOC00907,). IRS-type PTB domain has an average length of about 100 amino acids. It binds to the insulin receptor through the Asn-Pro-Xaa-Tyr(P) motif found in many tyrosine-phosphorylated proteins. This domain is found in IRS/Dok/SNT proteins that are the major adapters for RTK and cytokine signaling. This domain binds both peptides and headgroups of phosphatidylinositides, utilizing two distinct binding motifs to mediate spatial organization and localization within cells. The IRS-type PTB domain is found alone or in ...
The learncoil program is a general iterative method that extends the two-stranded coiled coil prediction program paircoil to the identification of other types of coiled coils. Previously, the learncoil program successfully identified three-stranded coiled coils (24).. Iterative approaches similar to learncoil have been applied to sequence alignment and motif recognition (16, 37-41). Each method repeats two steps. First, a scoring algorithm is used to scan a database of sequences for regions thought to represent the motif of interest. Second, selected residues are used to update the parameters of the scoring algorithm (e.g., a weight matrix, profile, or probability table). The updated parameters change the regions identified in the next iteration, and usually these two steps are repeated until convergence occurs.. learncoil combines several strategies to achieve good performance without identifying false-positive sequences (24). First, instead of choosing all sequences that score above a cutoff, ...

Activation of cytoplasmic tyrosine kinase activity is required for T cell receptor (TCR)-dependent lymphocyte activation (1). Adapter proteins serve as substrates for these kinases and as such may function to couple the TCR with downstream signaling events (2-6). SLP-76 is a hematopoietic cell-specific adapter protein that is phosphorylated rapidly on NH2-terminal tyrosine residues after TCR ligation (3), providing a binding site for the Src homology 2 (SH2) domain of Vav (7). SLP-76 also contains a central proline-rich region that associates constitutively with the SH3 domains of Grb2 (8). In addition, SLP-76 has a COOH-terminal SH2 domain that inducibly associates with SLAP-130 (SLP-76-associated phosphoprotein of 130 kD) and an unidentified 62-kD tyrosine phosphoprotein (5, 8, 9). The ability of SLP-76 to augment TCR-dependent nuclear factor of activated T cells (NFAT) activation when transiently overexpressed in a T cell line is dependent on the presence of each of these domains, suggesting ...
Catalytic domain of C-terminal Src kinase-like Protein Tyrosine Kinases. Protein Tyrosine Kinase (PTK) family; C-terminal Src kinase (Csk) subfamily; catalytic (c) domain. The Csk subfamily is composed of Csk, Chk, and similar proteins. The PTKc family is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, and phosphoinositide 3-kinase (PI3K). PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Csk subfamily kinases are cytoplasmic (or nonreceptor) tyr kinases containing the Src homology domains, SH3 and SH2, N-terminal to the catalytic tyr kinase domain. They negatively regulate the activity of Src kinases that are anchored to the plasma membrane. To inhibit Src kinases, Csk and Chk are translocated to the membrane via binding to specific transmembrane proteins, G-proteins, or adaptor proteins near the membrane. Csk catalyzes the tyr ...

Chronic myeloid leukemia is characterized by the Philadelphia (Ph1) translocation t(9;22) that generates a hybrid gene, bcr/abl, translated to a Mr210,000 tyrosine kinase (p210bcr/abl) with transforming activity for hematopoietic cells. Hematopoietic cell transformation by p210bcr/abl seems to involve activation of the Ras signaling pathway by at least two different signaling intermediates, growth factor receptor-bound protein 2 and Src homology and collagen protein, but additional signaling proteins are likely to be required as well. In an effort to identify additional phosphoproteins activated by p210bcr/abl, we studied the murine, interleukin 3-dependent, myeloid cell line, 32D, and a bcr/abl-transfected, factor-independent subline, 32Dp210. The analysis of whole-cell lysates of 32D and 32Dp210 cells showed that several proteins with a molecular weight of Mr50,000-60,000 were phosphorylated on tyrosine residues in 32Dp210 cells. Because Src family kinases have an apparent molecular weight of ...
Adapter molecule crk also known as proto-oncogene c-Crk or p38 is a protein that in humans is encoded by the CRK gene. The CRK protein participates in the Reelin signaling cascade downstream of DAB1. Adapter molecule crk is a member of an adapter protein family that binds to several tyrosine-phosphorylated proteins. This protein has several SH2 and SH3 domains (src-homology domains) and is involved in several signaling pathways, recruiting cytoplasmic proteins in the vicinity of tyrosine kinase through SH2-phosphotyrosine interaction. The N-terminal SH2 domain of this protein functions as a positive regulator of transformation whereas the C-terminal SH3 domain functions as a negative regulator of transformation. Two alternative transcripts encoding different isoforms with distinct biological activity have been described. Crk together with CrkL participates in the Reelin signaling cascade downstream of DAB1. v-Crk, a transforming oncoprotein from avian sarcoma viruses, is a fusion of viral gag ...
The Src homology 2 (SH2) domain is a protein interaction domain (PID) contained within SRC and other intracellular signal-transducing proteins, many of which drive tumorigenesis, which mediates protein-protein interactions via the docking of SH2 domain-containing proteins to phosphotyrosine (pY) residues on other proteins. Membrane lipids have recently been shown to regulate protein-protein interactions mediated by a different PID and to bind to several SH2 domains. To elucidate the role of lipids in SH2 domain-mediated protein-protein interactions and signal transduction, Park, Sheng, Silkov, Jung, and colleagues performed surface plasmon resonance analysis to systematically characterize the binding affinities of 76 of the 121 known SH2 domains for plasma membrane (PM)-mimetic vesicles which recapitulate the lipid profile of cytofacial PM. Sixty-eight out of the 76 SH2 domains analyzed exhibited moderately high to high levels of affinity for PM-mimetic vesicles. Twelve of 18 SH2 domains ...

The findings presented here support a role for the RhoGEF Trio in axon outgrowth and guidance in mammals. We show that Trio and DCC interact in the embryonic brain, most likely independently of netrin-1. Coexpression of DCC and Trio with Nck-1 and PAK1 suggests that the Trio-DCC interaction probably occurs via the interaction of Trio with PAK1. Furthermore, the N terminus region of Trio comprising the Sec-14 and the spectrin domains mediates the interaction with PAK1. However, it still remains to be determined whether the interaction between Trio and PAK1 is direct. Altogether, these data are consistent with the results obtained in D. melanogaster, where D-Trio genetically interacts with DOCK, PAK, and Rac in controlling axon guidance of photoreceptors (36). Since Nck-1 binds to DCC through its first and third SH3 domains (27) and PAK1 binds to the second SH3 domain of Nck-1 (8), it is tempting to postulate that a cascade of molecular events implicating Nck-1-PAK interaction serves to bridge ...
