Peptide Name: KIT (933-939) pY936

Product Use: Services as a blocking peptide for use with the Kit-pY936 rabbit polyclonal antibody (Cat. No.: AB-PK673) that is also available from Kinexus. This phosphopeptide may also be useful as a substrate for screening the phosphatase activity of protein phosphatases. The peptide sequence is located in the C-terminal of the kinase after the catalytic domain. Y936 phosphorylation induces interaction with APS, CBL, BRB2 and GRB7.

Scientific Background: Kit (SCFR) is a protein-tyrosine kinase of the TK group and PDGFR family. It is a receptor kinase that binds SCF/KitLG. Mast,stem cell growth factor (steel factor) binding induces Kit dimerization and autophosphorylation. Protein interactions are induced with phosphorylation at Y568 (with APS, Cbl, SHP2, & Src), Y900 (with Crk & PIK3C2A) and Y936 (with APS, Cbl, Grb2 & Grb7). Phosphorylation of S741 and S746 inhibits the kinase activity of Kit. Kit can mediate cell proliferation, survival, hematopoiesis, gametogenesis, stem cell maintenance, mast cell development, function, and migration, as well as melanogenesis. Some substrates that Kit can phosphorylate include PIK3R1, PLCG1, SH2B2/APS and CBL.This kinase is highly expressed and widely distributed in most tested human tissues. It was first identified as the cellular homologue of the feline sarcoma viral oncogene v-kit. Mutations in Kit are associated with gastrointestinal stromal tumors (GIST), mast cell leukemia, acute myelogenous leukemia (AML), and piebaldism. Kit has also been linked with the development of colorectal adenocarcinomas and melanoma progression. Insertional mutagenesis studies in mice also support a role for this protein kinase in mouse cancer oncogenesis.
