  • FunctionInactive tyrosine kinase involved in Wnt signaling pathway. Component of both the non-canonical (also known as the Wnt/planar cell polarity signaling) and the canonical Wnt signaling pathway. Functions in cell adhesion, cell migration, cell polarity, proliferation, actin cytoskeleton reorganization and apoptosis. Has a role in embryogenesis, epithelial tissue organization and angiogenesis.
  • Tissue specificityHighly expressed in lung, liver, pancreas, kidney, placenta and melanocytes. Weakly expressed in thyroid gland, ovary, brain, heart and skeletal muscle. Also expressed in erythroleukemia cells. But not expressed in colon.
  • Sequence similaritiesBelongs to the protein kinase superfamily. Tyr protein kinase family. Insulin receptor subfamily.
    Contains 7 Ig-like C2-type (immunoglobulin-like) domains.
    Contains 1 protein kinase domain.
  • DomainThe protein kinase domain is predicted to be catalytically inactive.
  • Post-translational
    MMP14 cleaves PTK7 between Pro-621 and Leu-622 generating an N-terminal soluble (70 kDa) fragment and a membrane C-terminal (50 kDa) fragment. Proteolysis by MMP14 regulates PTK7 function in non-canonical Wnt signaling pathway.
  • Cellular localizationMembrane. Cell junction. Colocalizes with MMP14 at cell junctions. Also localizes at the leading edge of migrating cells.
