General notes
Focal Adhesion Kinase is a 125 kDa non-receptor protein tyrosine kinase that plays a key role in signalling by growth factors, extracellular matrix and stress signals. Indeed, Focal Adhesion Kinase plays a central role in cell spreading, differentiation, migration, cell death and acceleration of the G1 to S phase transition of the cell cycle. Cyclin-dependent kinase-5 (Cdk5), a serine/threonine kinase and an important regulator in brain development, has been found to be essential for phosphorylation at serine 732. In the context of the Focal Adhesion Kinase-Related Non-Kinase (FRNK), the c-terminal non-kinase domain of Focal Adhesion Kinase that acts as a dominant negative inhibitor of Focal Adhesion Kinase signalling, other serine kinases appear to readily phosphorylate this same site. The functional significance of phosphorylation on serine 732 is yet to be determined.
The Life Science industry has been in the grips of a reproducibility crisis for a number of years. Abcam is leading the way in addressing this with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.

Purification notes
Purified from rabbit serum by sequential epitope-specific chromatography. The antibody has been negatively preadsorbed using (i) a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated Focal Adhesion Kinase enzyme and (ii) a generic serine phosphorylated peptide to remove antibody that is reactive with phosphoserine, irrespective of the sequence. The final product is generated by affinity chromatography using a Focal Adhesion Kinase-derived peptide that is phosphorylated at serine 732. -

Function
Non-receptor protein-tyrosine kinase implicated in signaling pathways involved in cell motility, proliferation and apoptosis. 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. Microtubule-induced dephosphorylation at Tyr-397 is crucial for the induction of focal adhesion disassembly. Plays a potential role in oncogenic transformations resulting in increased kinase activity. -
Tissue specificity
Expressed in all organs tested, in lymphoid cell lines, but most abundantly in brain. -
Sequence similarities
Belongs to the protein kinase superfamily. Tyr protein kinase family. FAK subfamily.
Contains 1 FERM domain.
Contains 1 protein kinase domain. -
Domain
The first Pro-rich domain interacts with the SH3 domain of CRK-associated substrate (BCAR1) and CASL.
The carboxy-terminal region is the site of focal adhesion targeting (FAT) sequence which mediates the localization of FAK1 to focal adhesions. -
Post-translational
modificationsPhosphorylated on 6 tyrosine residues upon activation. Microtubule-induced dephosphorylation at Tyr-397 could be catalyzed by PTPN11 and regulated by ZFYVE21. Dephosphorylated by PTPN11 upon EPHA2 activation by its ligand EFNA1. -
Cellular localization
Cell junction > focal adhesion. Cell membrane. Constituent of focal adhesions. - Information by UniProt

Western blot - Anti-FAK (phospho S732) antibody (ab4792)Influence of cdk5: Extracts prepared from cdk5 +/- (1, 3) and cdk5 -/- (2, 4) mouse brain lysates were resolved by SDS-PAGE on a 10% Tris-glycine gel and transferred to PVDF. The membrane was incubated with either FAK pan antibody (1, 2), or with 0.34µ g/mL ab4792 antibody (3, 4). After washing, membranes were incubated with goat F(ab’)2 anti-rabbit IgG alkaline phosphatase and signals were detected using the Tropix WesternStar method. The data show that cdk5 is essential for phosphorylation of FAK at serine 732. Other kinases appear to phosphorylate FRNK on this site.
