PTEN was discovered as a tumor suppressor with lipid and protein phosphatase activity. Heterozygous loss of PTEN in mice contribute to the development of a variety of types of cancer, suggesting that insufficient PTEN activity results in increased cancer susceptibility. PTEN negatively regulates the PI3K/AKT pathway by dephosphorylating the second messenger phosphoinositide 3,4,5-triphosphate (PIP3) produced by phosphoinositide 3-kinase (PI3K), which results in inhibition of abnormal cell proliferation. Despite the hydrolysis function of PIP3, the nuclear population of PTEN possesses greater tumor suppressive activities, regulates gene expression, differentiation, and cell cycle progression.Product Details

- 403 amino acids, predicted molecular weight of 47 kD, and observed molecular weight of 54 kD. Contains a C2 tensin-like domain responsible for lipid binding and membrane localization.
Cytoplasm (unubiquitinated form); nucleus (mono-ubiquitinated form).
- PTEN functions as a tumor suppressor, modulating the PI3K-AKT-mTOR signaling pathway. It exerts phosphatase activity, dephosphorylating serine, threonine, and tyrosine phosphorylated proteins. In addition, dephosphorylates phospholipids, removing a phosphate from phosphatidylinositol-3,4,5-trisphosphate. The lipid phosphatase activity is required for its tumor suppressor function.
- Interacts with MAIG2, MAIG3, MAST1, MAST3, NEDD4, NDFIP1, NDFIP2, USP7, ROCK1, and XIAP. The unphosphorylated form interacts with AIP1, DLG1 and MAS.T2.
