Rabbit polyclonal to FAK ( phospho S722 )Focal Adhesion Kinase is a non-receptor protein tyrosine kinase discovered as a substrate for Src and it is a key protein in integrin, growth factor and bioactive peptide signaling. 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. Focal Adhesion Kinase regulation includes phosphorylation at multiple tyrosine and serine residues. Phosphorylation of tyrosine generally is associated with positive regulation and growth promotion; however, dephosphorylation at these sites occurs as cells enter mitosis (M-Phase of the cell cycle). In contrast, serine phosphorylation either remains high or is increased as cells enter mitosis. The role of phosphorylation at Ser722 is currently being actively investigated.
