WB 1/10000 - 1/50000. Predicted molecular weight: 119 kDa.
  • Application notesIs unsuitable for Flow Cyt,ICC,IHC-P or IP.
  • Target

    • FunctionNon-receptor protein-tyrosine kinase implicated in signaling pathways involved in cell motility, proliferation and apoptosis. Activated by tyrosine-phosphorylation in response to either integrin clustering induced by cell adhesion or antibody cross-linking, or via G-protein coupled receptor (GPCR) occupancy by ligands such as bombesin or lysophosphatidic acid, or via LDL receptor occupancy. Microtubule-induced dephosphorylation at Tyr-397 is crucial for the induction of focal adhesion disassembly. Plays a potential role in oncogenic transformations resulting in increased kinase activity.
    • Tissue specificityExpressed in all organs tested, in lymphoid cell lines, but most abundantly in brain.
    • Sequence similaritiesBelongs to the protein kinase superfamily. Tyr protein kinase family. FAK subfamily.
      Contains 1 FERM domain.
      Contains 1 protein kinase domain.
    • DomainThe first Pro-rich domain interacts with the SH3 domain of CRK-associated substrate (BCAR1) and CASL.
      The carboxy-terminal region is the site of focal adhesion targeting (FAT) sequence which mediates the localization of FAK1 to focal adhesions.
    • Post-translational
      Phosphorylated on 6 tyrosine residues upon activation. Microtubule-induced dephosphorylation at Tyr-397 could be catalyzed by PTPN11 and regulated by ZFYVE21. Dephosphorylated by PTPN11 upon EPHA2 activation by its ligand EFNA1.
    • Cellular localizationCell junction > focal adhesion. Cell membrane. Constituent of focal adhesions.
