Informations sur les Gènes et les Protéines
Résumé UniProt
Inactive 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.
Résumé Entrez
This gene encodes a member of the receptor protein tyrosine kinase family of proteins that transduce extracellular signals across the cell membrane. The encoded protein lacks detectable catalytic tyrosine kinase activity, is involved in the Wnt signaling pathway and plays a role in multiple cellular processes including polarity and adhesion. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.
Spécificité tissulaire
Highly 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.
Similitudes de séquence
Belongs to the protein kinase superfamily. Tyr protein kinase family. Insulin receptor subfamily.
Modification post-traductionnelle
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.
Localisation cellulaire
Membrane. Cell junction.
Colocalizes with MMP14 at cell junctions. Also localizes at the leading edge of migrating cells.
