  • Function
    Tyrosine phosphatase which dephosphorylates or contributes to the dephosphorylation of CTNND1, PDGFRB, MET, RET (variant MEN2A), KDR, LYN, SRC, MAPK1, MAPK3, EGFR, TJP1, OCLN, PIK3R1 and PIK3R2. Plays a role in cell adhesion, migration, proliferation and differentiation. Involved in vascular development. Regulator of macrophage adhesion and spreading. Positively affects cell-matrix adhesion. Positive regulator of platelet activation and thrombosis. Negative regulator of cell proliferation. Negative regulator of PDGF-stimulated cell migration; through dephosphorylation of PDGFR. Positive regulator of endothelial cell survival, as well as of VEGF-induced SRC and AKT activation; through KDR dephosphorylation. Negative regulator of EGFR signaling pathway; through EGFR dephosphorylation. Enhances the barrier function of epithelial junctions during reassembly. Negatively regulates T-cell receptor (TCR) signaling. Upon T-cell TCR activation, it is up-regulated and excluded from the immunological synapses, while upon T-cell-antigen presenting cells (APC) disengagement, it is no longer excluded and can dephosphorylate PLCG1 and LAT to down-regulate prolongation of signaling.
  • Tissue specificity
    Expressed in the promyelocytic cell line HL60, the granulocyte-macrophage colony-stimulating factor-dependent leukemic cell line F-36P, and the interleukin-3 and erythropoietin-dependent leukemic cell line F-36E. Expressed predominantly in epithelial cells and lymphocytes. Enhanced expression at high cell density.
  • Sequence similarities
    Belongs to the protein-tyrosine phosphatase family. Receptor class 3 subfamily.
    Contains 9 fibronectin type-III domains.
    Contains 1 tyrosine-protein phosphatase domain.
  • Post-translational
    modifications
    N- and O-glycosylated.
  • Cellular localization
    Cell membrane. Cell projection > ruffle membrane. Cell junction. After T cell stimulation, it is temporarily excluded from immunological synapses.
  • Information by UniProt
