|Other Accession||NP_002833.2, 5794|
|Calculated MW||122352 Da|
|Other Names||Receptor-type tyrosine-protein phosphatase H, R-PTP-H, 18.104.22.168, Stomach cancer-associated protein tyrosine phosphatase 1, SAP-1, Transmembrane-type protein-tyrosine phosphatase type H, PTPRH, SAP1|
|Format||0.5 mg/ml in Tris saline, 0.02% sodium azide, pH7.3 with 0.5% bovine serum albumin|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||PTPRH Antibody (interal region) is for research use only and not for use in diagnostic or therapeutic procedures.|
|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 ZAP70. 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.|
|Cellular Location||Membrane; Single-pass type I membrane protein. Cytoplasm|
|Tissue Location||Expressed at high levels in the brain, spleen and liver and at 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|
