Product details:
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.

Properties and Storage Information:
Form-Liquid, Purification technique-Affinity purification Immunogen, 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., Storage buffer-pH: 7.3Preservative: 0.05% Sodium azideConstituents: PBS, 2.5% Glycerol (glycerin, glycerine), 0.1% BSA, Shipped at conditions-Blue Ice, Appropriate short-term storage conditions-+4°C, Appropriate long-term storage conditions--20°C, Aliquoting information-Upon delivery aliquot, Storage information-Avoid freeze / thaw cycle

Focal Adhesion Kinase (FAK) also known as Protein Tyrosine Kinase 2 (PTK2) is a non-receptor tyrosine kinase. This protein has a molecular weight of approximately 125 kDa. FAK is expressed at high levels in brain muscle and liver tissues. Mechanically FAK plays a role in cellular adhesion and migration by regulating integrin signaling and cell-extracellular matrix interactions. FAK auto-phosphorylates at tyrosine residue 397 creating a binding site for Src family kinases and promoting downstream signaling pathways.
Biological function summary
Focal Adhesion Kinase participates in the formation of focal adhesions which are complexes that connect the cytoskeleton to the extracellular matrix. The FAK protein functions as an important signaling node in these structures allowing for the assembly of multiprotein signal transduction complexes. FAK also controls cellular processes such as spreading motility and survival. The interaction with proteins such as Src kinases paxillin and talin facilitates its biological roles in cell signaling.
Pathways
Focal Adhesion Kinase engages in the regulation of the MAPK/ERK signaling pathway and the PI3K/AKT pathway. These pathways are instrumental for cell proliferation survival and migration. In these pathways FAK interacts with proteins such as PI3K Grb2 and Sos linking integrin-mediated signals with downstream effects that influence cell behavior and survival.
Altered FAK signaling has ties to cancer progression and metastasis as well as cardiovascular diseases. In cancer the overexpression of FAK and its interaction with proteins like Src and VEGFR can drive tumor growth and angiogenesis. In cardiovascular diseases improper FAK activation can lead to aberrant heart tissue remodeling and associated pathologies. Abnormalities in FAK signaling pathways can therefore contribute significantly to the development and progression of these diseases.
