PTEN Enzyme, active (Echelon Product Code: E-3000 10UG)
| Description: | PTEN Enzyme, active is a N-Terminal GST-Tagged, recombinant human PTEN (Phosphatase and Tensin Homolog), 76kD, purified from E.coli using glutathione-sepharose column chromatography. Storage: Store product -70 °C. Enzyme is stable for at least 6 months at -70 °C as undiluted stock Specificity: PTEN selectively removes phosphate from the 3" position of the inositol ring of PtdIns(3, 4, 5)P(3) Specific Activity: request Certificate of Analysis (COA) The PTEN enzyme is a 3-phosphoinositide phosphatase that converts PI(3, 4, 5)P(3) to PI(4, 5)P(2); thus opposing PKB/Akt activation by PI3-K. PTEN is involved in neuronal stem cell proliferation and self-renewal, cardiac myocyte hypertrophy and contractility, and a wide range of developmental processes. PTEN, however, is best known for its role as a tumor suppressor. Loss of PTEN activity results in accumulation of PI(3, 4, 5)P(3), abnormal activation of PKB/Akt, unregulated cell growth, suppression of apoptosis, and increase tumorigenesis in a number of human tissues. It has also been proposed that PTEN is a candidate for targeted chemotherapy because certain anti-cancer agents preferentially destroy tumors with PTEN mutations. In addition to this direct role in cancer, PTEN also indirectly regulates cancer-associated pathways including VEGF-mediated angiogenesis among others. 1. Brooks, R., et al. (2010).
