FAK (pY397) (Focal Adhesion Kinase) Mouse anti-Human, Unlabeled, Clone: 14, BD

Description

• Focal Adhesion Kinase (FAK) is a cytoplasmic tyrosine kinase that colocalizes with integrins in focal adhesions
• This cellular localization is directed by a 125 amino acid sequence at the C-terminus called the “Focal Adhesion Targeting” sequence (FAT)
• The binding of extracellular matrix ligands to integrins triggers autophosphorylation at Tyr-397, and activation of FAK through phosphorylation of Tyr residues (Tyr-576 and Tyr577) in the kinase domain activation loop
• For example, cell adhesion to a fibronectin substratum involves concurrent activation of Src and phosphorylation of the FAK activation loop
• In addition, phosphorylation of other Tyr residues (Tyr-925, and Tyr-861) creates binding sites for SH2 domains of intracellular signaling molecules such as Src, PI3 kinase, and Grb2
• FAK's ability to bind numerous structural and signaling proteins via a variety of interactions is important for FAK activation level, and for FAK interaction with a variety of substrates localized to sites of cell adhesion
• Thus, FAK activity is regulated by a complex set of phosphorylation sites, and thisphospho-regulation could be important for cell motility, cell growth, cytoskeletal organization, and adhesion-dependent cell survival
