What is the function of this protein?
Tyrosine phosphatase which dephosphorylates or contributes to the dephosphorylation of CTNND1, FLT3, PDGFRB, MET, KDR, LYN, SRC, MAPK1, MAPK3, EGFR, TJP1, OCLN, PIK3R1 and PIK3R2 (By similarity).  Plays a role in cell adhesion, migration, proliferation and differentiation (PubMed:18249142).  Involved in vascular development (PubMed:12588999).  May be involved in the mechanism of contact inhibition of cell growth (PubMed:12771128).  Regulator of macrophage adhesion and spreading (PubMed:19268662).  Positively affects cell-matrix adhesion (PubMed:12833140).  Positive regulator of platelet activation and thrombosis (PubMed:19246339).  Negative regulator of cell proliferation (By similarity).  Negative regulator of PDGF-stimulated cell migration; through dephosphorylation of PDGFR (PubMed:12833140).  Positive regulator of endothelial cell survival, as well as of VEGF-induced SRC and AKT activation; through KDR dephosphorylation (By similarity).  Negative regulator of EGFR signaling pathway; through EGFR dephosphorylation (By similarity).  Enhances the barrier function of epithelial junctions during reassembly (By similarity).  Negatively regulates T-cell receptor (TCR) signaling (By similarity).  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 (PubMed:12913111).
What are the official names of this protein?
Receptor-type tyrosine-protein phosphatase eta, Protein-tyrosine phosphatase eta, R-PTP-eta, HPTP beta-like tyrosine phosphatase, Protein-tyrosine phosphatase receptor type J, R-PTP-J, Susceptibility to colon cancer 1.
What is the protein family that this protein belongs to?
Belongs to the protein-tyrosine phosphatase family. Receptor class 3 subfamily.
What are the subcellular locations of this protein?
Cell membrane; Single-pass type I membrane protein. Cell projection, ruffle membrane. Cell junction. Note=After T- cell stimulation, it is temporarily excluded from immunological synapses. Found at cell borders.
