Y576/Y577 (PTK2) Antibody – Rabbit

FAK: a tyrosine kinase of the FAK family required for cell migration and contact-dependent survival signaling. Activated by tyrosine-phosphorylation in response to either integrin clustering induced by cell adhesion or antibody cross-linking, or via G-protein coupled receptor (GPCR) occupancy by ligands such as bombesin or lysophosphatidic acid, or via LDL receptor occupancy. Downstream of integrins and Src, upstream of Ras/MAPK. Localizes to focal adhesions that form between cells growing in the presence of extracellular matrix constituents. Interacts with CAS family members and with GIT1, SORBS1 and BCAR3. Interacts with Shb. Required for full Ras transformation of fibroblasts. Increased expression in breast and other cancers, related to chromosome 8q amplification. Overexpression and activation associated with increased migration, invasion and progression of ovarian cancer, and with progression in hepatocellular carcinoma, thyroid cancer, and acute myelogenous leukemia. siRNA increases chemosensitivity of pancreatic adenocarcinoma xenografts. Inhibitor: ISI15421 (antisense). Four splice-variant isoforms have been observed.
