Product Specific Information

MA5-15644 targets FAK in indirect ELISA, FACS, IF, and WB applications and shows reactivity with human samples.
The immunogen is a purified recombinant fragment of human FAK expressed in E. coli.
MA5-15644 detects FAK, which has a predicted molecular weight of approximately 119 kDa.

Target Information

Focal Adhesion Kinase (FAK) is a 125 kDa non-receptor protein tyrosine kinase that acts as a substrate for Src and is a key element of integrin signaling.
FAK plays an important role in cell spreading, differentiation, migration, cell death, and acceleration of the G1 to S phase transition of the cell cycle.
FAK has a central catalytic domain and a C-terminal tail that localizes it to focal adhesions, sites where cells attach to the extracellular matrix via surface integrin receptors.
Increased FAK tyrosine phosphorylation occurs upon integrin engagement with fibronectin. Adhesion of murine NIH3T3 fibroblasts to fibronectin promotes association of the Grb2 adapter protein and c-Src PTK with FAK in vivo, resulting in activation of ERK2 MAP kinase.
In v-Src-transformed NIH3T3 cells, 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, with Tyr925 identified as the binding site by site-directed mutagenesis.
Several transcript variants encoding different isoforms have been found for the FAK gene, but the full-length natures of only three of them have been determined.
