Yes SH3 domain
Structural highlights
FunctionYES_HUMAN Non-receptor protein tyrosine kinase that is involved in the regulation of cell growth and survival, apoptosis, cell-cell adhesion, cytoskeleton remodeling, and differentiation. Stimulation by receptor tyrosine kinases (RTKs) including EGRF, PDGFR, CSF1R and FGFR leads to recruitment of YES1 to the phosphorylated receptor, and activation and phosphorylation of downstream substrates. Upon EGFR activation, promotes the phosphorylation of PARD3 to favor epithelial tight junction assembly. Participates in the phosphorylation of specific junctional components such as CTNND1 by stimulating the FYN and FER tyrosine kinases at cell-cell contacts. Upon T-cell stimulation by CXCL12, phosphorylates collapsin response mediator protein 2/DPYSL2 and induces T-cell migration. Participates in CD95L/FASLG signaling pathway and mediates AKT-mediated cell migration. Plays a role in cell cycle progression by phosphorylating the cyclin-dependent kinase 4/CDK4 thus regulating the G1 phase. Also involved in G2/M progression and cytokinesis.[1] [2] [3] [4] [5] [6] Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMedSH3 domains from the Src family of tyrosine kinases represent an interesting example of the delicate balance between promiscuity and specificity characteristic of proline-rich ligand recognition by SH3 domains. The development of inhibitors of therapeutic potential requires a good understanding of the molecular determinants of binding affinity and specificity and relies on the availability of high quality structural information. Here, we present the first high-resolution crystal structure of the SH3 domain of the c-Yes oncogen. Comparison with other SH3 domains from the Src family revealed significant deviations in the loop regions. In particular, the n-Src loop, highly flexible and partially disordered, is stabilized in an unusual conformation by the establishment of several intramolecular hydrogen bonds. Additionally, we present here the first report of amyloid aggregation by an SH3 domain from the Src family.
