          Phospho-FAK (Tyr397) Antibody (44-625G) in ICC/IF

          HeLa cells were fixed prior to immunostaining with the Rabbit anti-FAK (pY397) monoclonal antibody. The signal was detected with an anti-rabbit FITC conjugated secondary antibody. The data shows that the antibody detected phosphorylated FAK localized at focal adhesions. Cells were counterstained with DAPI.

          Product Specific Information

          This antibody will cross-react with the corresponding autophosphorylation site on Proline-rich/Ca2+- activated tyrosine kinase (Pyk2), [pY402]. FAK [pY397] polyclonal antibody (Cat. No. 44-624G) does not cross-react with Pyk2.

          The antibody has been used in western blotting. Previous lots of this antibody have been used in immunocytochemistry. For western blotting applications, we recommend using the antibody at a 1:1,000 starting dilution. For immunofluorecence staining applications, we recommend a 1:50 starting dilution. Positive control used: Primary chicken embryo fibroblasts expressing human FAK and plated on fibronectin.

          We recommend a brief centrifugation before opening to settle vial contents. Then, apportion into working aliquots and store at -20° C. For shipment or short-term storage (up to one week), 2-8° C is sufficient. Expires one year from date of receipt when stored as instructed.

          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, which are 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, 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. 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.
