      Background InformationI. TEST PRINCIPLE
      The UPSTATE® colorimetric STAR (Signal Transduction Assay Reaction) ELISA kit is a solid phase sandwich enzyme linked immunosorbent assay that provides a fast, sensitive method to detect specific levels of signaling targets in whole cell extracts. The FAK plate is coated with a specific mouse monoclonal FAK capture antibody. Sample lysate or the standard included in the kit are incubated in the microwells allowing FAK antigen to be captured. The plate is then washed to remove any un-bound non-specific material. A specific rabbit anti-FAK antibody is added to detect the captured FAK on the plate. The unbound detection antibody is washed away followed by incubation with an HRP-conjugated anti-rabbit antibody. After the addition of TMB substrate and stop solution the absorbance is measured at 450 nm using a plate reader. This allows for a sensitive enzymatic detection of the sample.
      The entire assay takes less than 5 hours to complete with minimal hands-on time. Many of the reagents are supplied in ready-to use formulations for ease of use. The kit also includes a standard that is run as both a positive control and to generate a standard curve for FAK measurement.

      II. FAK BACKGROUND
      FAK (Focal Adhesion Kinase) is a non-receptor tyrosine kinase which localizes to focal adhesions and plays a key role in integrin-mediated signaling pathways regulating cell migration. It autophosphorylates on tyrosine 397 during adhesion and spreading, and is thought to be a critical transducer of adhesion-dependent growth and survival. FAK and it phosphorylation states have been implicated in cancer metastasis and tumor cell survival and adhesion-independent growth. Additionally, recent evidence indicates that elevation of FAK activity in human carcinoma cells is associated with increased invasive potential. A central role in tumor formation and progression suggest that FAK is an attractive target for therapeutic intervention.
      Cell surface integrins when engaged with their ligands lead to the recruitment of a number of intracellular proteins to specialized sites of the cytoplasmic face into focal adhesions. These focal adhesion plaques are composed of many proteins that include kinases, phosphatases, scaffolding proteins, and G-proteins. The activation of integrins leads to the tyrosine phosphorylation of several cytoplasmic proteins critical to the biochemical process, including FAK, Src, paxillin, tensin, and p130Cas. This clustering and activation of proteins at the membrane leads to the activation of many diverging signaling pathways that result in cytoskeletal re-organization. This starts with either the recruitment of Src and FAK to the plasma membrane following integrin or PI3 Kinase activation. The non-receptor protein-tyrosine kinases (PTKs) FAK and Src are key members of the focal adhesion complex. These PTKs co- Localize and associate with the transmembrane integrins and various downstream targets of certain growth factor receptors. The outcome of Src binding to FAK is the phosphorylation of several tyrosine residues in FAK and its related proteins, including the FAK autophosphorylation site Tyr397. This autophosphorylation occurs immediately after integrin clustering and allows for the association of FAK with various signaling proteins such as PI3 kinase, Grb2-Sos, p130Cas, and paxillin. The phosphorylation of FAK Tyr397 is crucial for many of the established biological roles of FAK, including cell migration, cell cycle progression, and prevention of anoikis, a form of detachment-induced apoptosis and is correlated with the invasiveness of tumors and is thought to be a pivotal player by modulating the turnover of focal adhesions to regulate cell migration. Phosphoinositide 3-Kinase (PI3 kinase or PI3K) also plays a role in cell migration via its binding to the autophosphorylation site (Tyr397) of FAK through one or both of its SH2 domains in the p85 subunit of PI3K. This is the same site in FAK that is bound by Src. In theory, the binding of PI3 kinase to FAK may be involved in activities like cell proliferation, apoptosis, and migration that are related to the phosphorylation of Tyr397. This is substantiated by the observation that AKT is downstream of PI3 kinase and is a mediator in preventing apoptosis. Therefore it is possible that FAK/PI3 kinase association may help regulate apoptosis.

      Entrez Gene Number
      Entrez Gene SummaryThis gene encodes a cytoplasmic protein tyrosine kinase which is found concentrated in the focal adhesions that form between cells growing in the presence of extracellular matrix constituents. The encoded protein is a member of the FAK subfamily of protein tyrosine kinases but lacks significant sequence similarity to kinases from other subfamilies. Activation of this gene may be an important early step in cell growth and intracellular signal transduction pathways triggered in response to certain neural peptides or to cell interactions with the extracellular matrix. At least four transcript variants encoding four different isoforms have been found for this gene, but the full-length natures of only two of them have been determined.
