Target

  • Function
    Non-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 specificity
    Expressed in all organs tested, in lymphoid cell lines, but most abundantly in brain.
  • Sequence similarities
    Belongs to the protein kinase superfamily. Tyr protein kinase family. FAK subfamily.
    Contains 1 FERM domain.
    Contains 1 protein kinase domain.
  • Domain
    The 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
    modifications
    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 localization
    Cell junction > focal adhesion. Cell membrane. Constituent of focal adhesions.

    Please suggest a suitable positive control for IHC-P with ab24781

    Thank you for your telephone enquiry yesterday afternoon.

    As discussed on the telephone, I am sorry to confirm that as far as we are aware, ab24781 has never been tested in IHC-P. All tested applications covered by the 6 month guaranteeare s...
