General description

SH3 domain-containing kinase-binding protein 1 (UniProt: Q925Q9; also known as Regulator of ubiquitous kinase, Ruk, SH3-containing expressed in tumorigenic astrocytes, SH3KBPI,) is encoded by the Sh3kbp1 (also known as Ruk, Seta) gene (Gene ID: 84357) in rat. SH3KBPI is a peripheral membrane protein that serves as an adapter protein involved in regulating diverse signal transduction pathways. It localizes in endocytic vesicles containing clustered receptors. It is shown to be highly expressed in the spinal cord. It can self-associate and form homotetramers. It contains three SH3 domains (aa 1-58; 98-157; and 311-372). SH3KBPI is involved in the regulation of endocytosis and lysosomal degradation of ligand-induced receptor tyrosine kinases, including EGFR and MET/hepatocyte growth factor receptor, through an association with CBL and endophilins. It can attenuate phosphatidylinositol 3-kinase activity by interaction with its regulatory subunit. It is also reported to plays a role in the regulation of cell morphology and cytoskeletal organization. Seven different isoforms of SH3KBP1 have been described that are produced by alternative splicing.
