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. Tyrosine 397 is the autophosphorylation site of FAK, and involved in its initial activation. This phosphorylated site binds Src family SH2 domains and the p85 subunit of PI3-Kinase, and activates cell migration and invasion.
Specificity
Also reacts with FAK-Related Non-Kinase (FRNK).
Immunogen
The antiserum was produced against a chemically synthesized phosphopeptide derived from the region of human FAK that contains serine 732. The sequence is conserved in mouse, rat and chicken.
Physical form
Solution in Dulbecco′s phosphate buffered saline (without Mg2+ and Ca2+), pH 7.3, containing 50% glycerol, 1.0 mg/ml BSA (IgG and protease free) and 0.05% sodium azide.

Neuronal migration is crucial for development of the mammalian-specific six-layered cerebral cortex. Migrating neurons are known to exhibit distinct features; they form a cytoplasmic dilation, a structure specific to migrating neurons, at the proximal region of the leading process, followed
