Space-filling model of the PTEN protein (blue) complexed with tartaric acid (brown) [5] Phosphatase and tensin homolog (PTEN) is a phosphatase in humans and is encoded by the PTEN gene. [6] Mutations of this gene are a step in the development of many cancers, specifically glioblastoma, lung cancer, breast cancer, and prostate cancer.
PTEN also refers to a member of the class, phosphatase and tensin homolog. [citation needed] This enzyme participates in 10 metabolic pathways: inositol phosphate metabolism, phosphatidylinositol signaling system, p53 signaling pathway, focal adhesion, tight junction, endometrial cancer, glioma, prostate cancer, melanoma, and small cell lung ...
The PI3K/AKT pathway has a natural inhibitor called Phosphatase and tensin homolog whose function is to limit proliferation in cells, helping to prevent cancer. Knocking out PTEN has been shown to increase the mass of the brain because of the unregulated proliferation that occurs. [3] PTEN works by dephosphorylating PIP3 to PIP2 which limits ...
The PTP domain is unlikely to be active in tensin 1, owing to mutation of the essential nucleophilic cysteine in the signature motif to asparagine. [5] Nevertheless, phosphatidylinositol-3,4,5-trisphosphate 3-phosphatase, the well-studied tumor suppressor that is better known as PTEN, gets its name from homology with PTPs and tensin 1. [6]

Phosphatase and tensin homolog (PTEN) antagonises PI3K by converting PI(3,4,5)P 3 into PI(4,5)P 2. Loss of PTEN function leads to over-activation of Akt and is common in cancer cells (PTEN is a tumour suppressor). SH2-containing Inositol Phosphatase (SHIP) also dephosphorylates PI(3,4,5)P 3, at the 5' position of the inositol ring. [22]

RhoA-GTP stimulates the phospholipid phosphatase activity of PTEN (phosphatase and tensin homologue), a human tumor suppressor protein. This stimulation seems to depend on ROCK. [8] [9] In this way, PTEN is important to prevent uncontrolled cell division as is exhibited in cancer cells.
