176-281 2.69e-26

Src Homology 3 domain superfamily; Src Homology 3 (SH3) domains are protein interaction domains that bind proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. Thus, they are referred to as proline-recognition domains (PRDs). SH3 domains are less selective and show more diverse specificity compared to other PRDs. They have been shown to bind peptide sequences that lack the PxxP motif; examples include the PxxDY motif of Eps8 and the RKxxYxxY sequence in SKAP55. SH3 domain containing proteins play versatile and diverse roles in the cell, including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies, among others. Many members of this superfamily are adaptor proteins that associate with a number of protein partners, facilitating complex formation and signal transduction.

SAM domain of SASH1 proteins, repeat 1; SAM (sterile alpha motif) repeat 1 of SASH1 proteins is a predicted protein-protein interaction domain. Members of this subfamily are putative adaptor proteins. They appear to mediate signal transduction. SASH1 can bind 14-3-3 proteins in response to IGF1/phosphatidylinositol 3-kinase signaling. SASH1 was found upregulated in different tissues including thymus, placenta, lungs and downregulated in some breast tumors, liver metastases and colon cancers, relative to corresponding normal tissues. SASH1 is a potential candidate for a tumor suppressor gene in breast cancers. At the same time, downregulation of SASH1 in colon cancer is associated with metastasis and a poor prognosis.

176-282 3.67e-21

Src homology 3 domain of SAM And SH3 Domain Containing Protein 1; SASH1 is a potential tumor suppressor in breast and colon cancer. Its decreased expression is associated with aggressive tumor growth, metastasis, and poor prognosis. It is widely expressed in normal tissues (except lymphocytes and dendritic cells) and is localized in the nucleus and the cytoplasm. SASH1 interacts with the oncoprotein cortactin and is important in cell migration and adhesion. It is a member of the SLY family of proteins, which are adaptor proteins containing a central conserved region with a bipartite nuclear localization signal (NLS) as well as SAM (sterile alpha motif) and SH3 domains. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

Src homology 3 domain of SAM And SH3 Domain Containing Proteins; This subfamily, also called the SLY family, is composed of SAM And SH3 Domain Containing Protein 1 (SASH1), SASH2, SASH3, and similar proteins. These are adaptor proteins containing a central conserved region with a bipartite nuclear localization signal (NLS) as wells as SAM (sterile alpha motif) and SH3 domains. SASH1 is a potential tumor suppressor in breast and colon cancer. It is widely expressed in normal tissues (except lymphocytes and dendritic cells) and is localized in the nucleus and the cytoplasm. SASH1 interacts with the oncoprotein cortactin and is important in cell migration and adhesion. SASH2 (also called SAMSN-1, SLY2, HACS1 or NASH1) and SASH3 (also called SLY/SLY1) are expressed mainly in hematopoietic cells, although SASH2 is also found in endothelial cells as well as myeloid leukemias and myeloma. SASH2 was found to be differentially expressed in malignant haematopoietic cells and in colorectal tumors, and is a potential tumor suppressor in lung cancer. SASH3 is essential in the full activation of adaptive immunity and is involved in the signaling of T cell receptors. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

SAM domain of Ship2 lipid phosphatase proteins; SAM (sterile alpha motif) domain of Ship2 subfamily is a protein-protein interaction domain. Ship2 proteins are lipid phosphatases (Phosphatidylinositol-3,4,5-trisphosphate 5-phosphatase 2) containing an N-terminal SH2 domain, a central phosphatase domain and a C-terminal SAM domain. Ship2 is involved in a number of PI3K signaling pathways. For example, it plays a role in regulation of the actin cytoskeleton remodeling, in insulin signaling pathways, and in EphA2 receptor endocytosis. SAM domain of Ship2 can interact with SAM domain of other proteins in these pathways, thus participating in signal transduction. In particular, SAM of Ship2 is known to form heterodimers with SAM domain of Eph-A2 receptor tyrosine kinase during receptor endocytosis as well as with SAM domain of PI3K effector protein Arap3 in the actin cytoskeleton signaling network. Since Ship2 plays a role in negatively regulating insulin signaling, it has been suggested that inhibition of its expression or function may contribute in treating type 2 diabetes and obesity-induced insulin resistance.

C-terminal Src Homology 3 domain of Ct10 Regulator of Kinase adaptor proteins; CRK adaptor proteins consists of SH2 and SH3 domains, which bind tyrosine-phosphorylated peptides and proline-rich motifs, respectively. They function downstream of protein tyrosine kinases in many signaling pathways started by various extracellular signals, including growth and differentiation factors. Cellular CRK (c-CRK) contains a single SH2 domain, followed by N-terminal and C-terminal SH3 domains. It is involved in the regulation of many cellular processes including cell growth, motility, adhesion, and apoptosis. CRK has been implicated in the malignancy of various human cancers. The C-terminal SH3 domain of CRK has not been shown to bind any target protein; it acts as a negative regulator of CRK function by stabilizing a structure that inhibits the access by target proteins to the N-terminal SH3 domain. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes by intramolecular interactions, changing the subcellular localization of signal pathway components, and mediating the formation of multiprotein complex assemblies.

247-279 5.01e-04

Src Homology 3 domain of Pak Interactive eXchange factors; PIX proteins are Rho guanine nucleotide exchange factors (GEFs), which activate small GTPases by exchanging bound GDP for free GTP. They act as GEFs for both Cdc42 and Rac 1, and have been implicated in cell motility, adhesion, neurite outgrowth, and cell polarity. Vertebrates contain two proteins from the PIX subfamily, alpha-PIX and beta-PIX. Alpha-PIX, also called ARHGEF6, is localized in dendritic spines where it regulates spine morphogenesis. Mutations in the ARHGEF6 gene cause X-linked intellectual disability in humans. Beta-PIX play roles in regulating neuroendocrine exocytosis, focal adhesion maturation, cell migration, synaptic vesicle localization, and insulin secretion. PIX proteins contain an N-terminal SH3 domain followed by RhoGEF (also called Dbl-homologous or DH) and Pleckstrin Homology (PH) domains, and a C-terminal leucine-zipper domain for dimerization. The SH3 domain of PIX binds to an atypical PxxxPR motif in p21-activated kinases (PAKs) with high affinity. The binding of PAKs to PIX facilitate the localization of PAKs to focal complexes and also localizes PAKs to PIX targets Cdc43 and Rac, leading to the activation of PAKs. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

They contain an N-terminal SYLF domain (also called DUF500) and a C-terminal SH3 domain. Ysc84p localizes to actin patches and plays an important in actin polymerization during endocytosis. The N-terminal domain of both Ysc84p and Lsb3p can bind and bundle actin filaments. A study of the yeast SH3 domain interactome predicts that the SH3 domains of Lsb3p and Lsb4p may function as molecular hubs for the assembly of endocytic complexes. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

Second Src Homology 3 domain of Nck adaptor proteins; Nck adaptor proteins regulate actin cytoskeleton dynamics by linking proline-rich effector molecules to protein tyrosine kinases and phosphorylated signaling intermediates. They contain three SH3 domains and a C-terminal SH2 domain. They function downstream of the PDGFbeta receptor and are involved in Rho GTPase signaling and actin dynamics. Vertebrates contain two Nck adaptor proteins: Nck1 (also called Nckalpha) and Nck2 (also called Nckbeta or Growth factor receptor-bound protein 4, Grb4), which show partly overlapping functions but also bind distinct targets. Their SH3 domains are involved in recruiting downstream effector molecules, such as the N-WASP/Arp2/3 complex, which when activated induces actin polymerization that results in the production of pedestals, or protrusions of the plasma membrane. The second SH3 domain of Nck appears to prefer ligands containing the APxxPxR motif. SH3 domains are protein interaction domains that usually bind to proline-rich ligands with moderate affinity and selectivity, preferentially a PxxP motif. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

Second Src Homology 3 domain (SH3B) of CD2-associated protein and similar proteins; This subfamily is composed of the second SH3 domain (SH3B) of CD2AP, CIN85 (Cbl-interacting protein of 85 kDa), and similar domains. CD2AP and CIN85 are adaptor proteins that bind to protein partners and assemble complexes that have been implicated in T cell activation, kidney function, and apoptosis of neuronal cells. They also associate with endocytic proteins, actin cytoskeleton components, and other adaptor proteins involved in receptor tyrosine kinase (RTK) signaling. CD2AP and the main isoform of CIN85 contain three SH3 domains, a proline-rich region, and a C-terminal coiled-coil domain. All of these domains enable CD2AP and CIN85 to bind various protein partners and assemble complexes that have been implicated in many different functions. SH3B of both proteins have been shown to bind to Cbl. In the case of CD2AP, its SH3B binds to Cbl at a site distinct from the c-Cbl/SH3A binding site. The CIN85 SH3B also binds ubiquitin. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

249-280 5.60e-03

Src homology 3 domain of Myosins Ie, If, and similar proteins; Myosins Ie (MyoIe) and If (MyoIf) are nonmuscle, unconventional, long tailed, class I myosins containing an N-terminal motor domain and a myosin tail with TH1, TH2, and SH3 domains. MyoIe interacts with the endocytic proteins, dynamin and synaptojanin-1, through its SH3 domain; it may play a role in clathrin-dependent endocytosis. In the kidney, MyoIe is critical for podocyte function and normal glomerular filtration. Mutations in MyoIe is associated with focal segmental glomerulosclerosis, a disease characterized by massive proteinuria and progression to end-stage kidney disease. MyoIf is predominantly expressed in the immune system; it plays a role in immune cell motility and innate immunity. Mutations in MyoIf may be associated with the loss of hearing. The MyoIf gene has also been found to be fused to the MLL (Mixed lineage leukemia) gene in infant acute myeloid leukemias (AML). SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

309-357 8.21e-03

SAM domain of Arap1,2,3 (angiotensin receptor-associated protein); SAM (sterile alpha motif) domain of Arap1,2,3 subfamily proteins (angiotensin receptor-associated) is a protein-protein interaction domain. Arap1,2,3 proteins are phosphatidylinositol-3,4,5-trisphosphate-dependent GTPase-activating proteins. They are involved in phosphatidylinositol-3 kinase (PI3K) signaling pathways. In addition to SAM domain, Arap1,2,3 proteins contain ArfGap, PH-like, RhoGAP and UBQ domains. SAM domain of Arap3 protein was shown to interact with SAM domain of Ship2 phosphatidylinositol-trisphosphate phosphatase proteins. Such interaction apparently plays a role in inhibition of PI3K regulated pathways since Ship2 converts PI(3,4,5)P3 into PI(3,4)P2. Proteins of this subfamily participate in regulation of signaling and trafficking associated with a number of different receptors (including EGFR, TRAIL-R1/DR4, TRAIL-R2/DR5) in normal and cancer cells; they are involved in regulation of actin cytoskeleton remodeling, cell spreading and formation of lamellipodia.
