功能： catalytic activity:Protein tyrosine phosphate + H(2)O = protein tyrosine + phosphate.,domain:The cytoplasmic domain mediates the interaction with LCK.,domain:The extracellular domain mediates homodimerization. One or more cysteines in the extracelllular domain is essential for the formation of dimers probably by forming a disulfide bond.,enzyme regulation:Regulated by reversible dimerization. Dimerization reduces its catalytic activity.,function:May contribute to contact inhibition of cell growth and motility by mediating the dephosphorylation of focal adhesion-associated substrates and thus negatively regulating integrin-promoted signaling processes. Induces apoptotic cell death by at least two distinct mechanisms: inhibition of cell survival signaling mediated by PI 3-kinase, Akt, and ILK and activation of a caspase-dependent proapoptotic pathway. Inhibits the basal activity of LCK and its activation in response to TCR stimulation and TCR-induced activation of MAP kinase and surface expression of CD69. Inhibits TCR-induced tyrosine phosphorylation of LAT and ZAP-70. Inhibits both basal activity of DOK1 and its CD2-induced tyrosine phosphorylation. Induces dephosphorylation of p130cas, focal adhesion kinase and c-Src. Reduces migratory activity of Jurkat cells.,induction:Induced at the early stage of hepatocellular carcinoma and is suppressed at later stages.,similarity:Belongs to the protein-tyrosine phosphatase family. Receptor class 3 subfamily.,similarity:Contains 1 tyrosine-protein phosphatase domain.,similarity:Contains 8 fibronectin type-III domains.,subunit:Homodimer; disulfide-linked (Probable). Interacts with LCK.,tissue specificity:Expressed at high levels in the brain, spleen and liver and at a lower levels in the heart and stomach. Expressed in pancreatic and colorectal cancer cells, but not in normal pancreas or colon. Expression in hepatocellular carcinoma is related to the differentiation status of the tumor and expression is inversely related to tumor aggressiveness.,
