Technical Data
FAK (Focal Adhesion Associated Protein Tyrosine Kinase, BC3)
Epitope localizes in the C-terminal (aa 853-1052) of human FAK protein. FAK is a widely expressed non-receptor protein tyrosine kinase (PTK). FAK has a central catalytic domain and a C-terminal tail that localizes it to focal adhesions, which are sites where cells attach to the extracellular matrix via surface integrin receptors. Increased FAK tyrosine phosphorylation occurs upon integrin engagement with fibronectin. Studies have shown that adhesion of murine NIH3T3 fibroblasts to fibronectin promotes association of the Grb2 adapter protein and c-Src PTK with FAK in vivo, and also results in activation of the ERK2 MAP kinase. In v-Src-transformed NIH3T3, the association of v-Src, Grb2, and Sos with FAK is independent of cell adhesion to fibronectin. In vitro the Grb2 SH2 domain binds directly to tyrosine-phosphorylated FAK, and the binding site has been identified as Tyr925 by site directed mutagenesis. Excellent for multiple biochemical applications.

Suitable for use in Immunofluorescence, Immunoprecipitation and Western Blotting. Other applications have not been tested.

Recommended Dilution:
Immunoprecipitation: 10ug/mg protein lysate. Use Protein A.
Western Blotting: 5-10ug/ml for 2hrs at RT
Optimal dilutions to be determined by the researcher.
