Peptide Competition : Cell extracts prepared from chick embryo fibroblasts expressing FAK and plated on fibronectin were resolved by SDS-PAGE on a 10% Tris-glycine gel. The proteins then were transferred to nitrocellulose and incubated with 0.50 μg/mL ab4804 antibody, following prior incubation with : (1) the phosphopeptide immunogen, (2) a generic phosphotyrosine containing peptide, (3) the non-phosphorylated peptide corresponding to the phosphopeptide, and (4) no peptide. After washing, membranes were incubated with goat F(ab’)2 anti-rabbit IgG alkaline phosphatase and bands were detected using the Tropix WesternStar detection method. The data show that only the phosphopeptide corresponding to this site blocks the antibody signal, demonstrating the specificity of the ab4804 antibody for this phosphorylated residue.

Product details

Focal Adhesion Kinase is a 125 kDa non-receptor protein tyrosine kinase that is a substrate for Src and a key element in growth factor and integrin signalling. 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. Tyr861 of Focal Adhesion Kinase is a major Src phosphorylation site that allows Focal Adhesion Kinase to bind to integrins and is also involved in cancer.

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 protein, and (ii) a generic tyrosine phosphorylated peptide to remove antibody that is reactive with phosphotyrosine (irrespective of the sequence). The final product is generated by affinity chromatography using a Focal Adhesion Kinase-derived peptide that is phosphorylated at tyrosine 861.

Supplementary information

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.

Target data

Non-receptor protein-tyrosine kinase that plays an essential role in regulating cell migration, adhesion, spreading, reorganization of the actin cytoskeleton, formation and disassembly of focal adhesions and cell protrusions, cell cycle progression, cell proliferation and apoptosis. Required for early embryonic development and placenta development. Required for embryonic angiogenesis, normal cardiomyocyte migration and proliferation, and normal heart development. Regulates axon growth and neuronal cell migration, axon branching and synapse formation; required for normal development of the nervous system. Plays a role in osteogenesis and differentiation of osteoblasts. Functions in integrin signal transduction, but also in signaling downstream of numerous growth factor receptors, G-protein coupled receptors (GPCR), EPHA2, netrin receptors and LDL receptors. Forms multisubunit signaling complexes with SRC and SRC family members upon activation; this leads to the phosphorylation of additional tyrosine residues, creating binding sites for scaffold proteins, effectors and substrates. Regulates numerous signaling pathways. Promotes activation of phosphatidylinositol 3-kinase and the AKT1 signaling cascade. Promotes activation of MAPK1/ERK2, MAPK3/ERK1 and the MAP kinase signaling cascade. Promotes localized and transient activation of guanine nucleotide exchange factors (GEFs) and GTPase-activating proteins (GAPs), and thereby modulates the activity of Rho family GTPases. Signaling via CAS family members mediates activation of RAC1. Phosphorylates NEDD9 following integrin stimulation (PubMed : 9360983). Recruits the ubiquitin ligase MDM2 to P53/TP53 in the nucleus, and thereby regulates P53/TP53 activity, P53/TP53 ubiquitination and proteasomal degradation. Phosphorylates SRC; this increases SRC kinase activity. Phosphorylates ACTN1, ARHGEF7, GRB7, RET and WASL. Promotes phosphorylation of PXN and STAT1; most likely PXN and STAT1 are phosphorylated by a SRC family kinase that is recruited to autophosphorylated PTK2/FAK1, rather than by PTK2/FAK1 itself. Promotes phosphorylation of BCAR1; GIT2 and SHC1; this requires both SRC and PTK2/FAK1. Promotes phosphorylation of BMX and PIK3R1. Isoform 6 (FRNK) does not contain a kinase domain and inhibits PTK2/FAK1 phosphorylation and signaling. Its enhanced expression can attenuate the nuclear accumulation of LPXN and limit its ability to enhance serum response factor (SRF)-dependent gene transcription.. Isoform 6. Isoform 6 (FRNK) does not contain a kinase domain and inhibits PTK2/FAK1 phosphorylation and signaling.
