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 ...
PtdIns(3,4,5)P 3 is dephosphorylated by the phosphatase PTEN on the 3 position, generating PI(4,5)P 2, and by SHIPs (SH2-containing inositol phosphatase) on the 5' position of the inositol ring, producing PI(3,4)P 2. [5] The PH domain in a number of proteins binds to PtdIns(3,4,5)P 3. Such proteins include Akt/PKB, [6] PDPK1, [7] Btk1, and ARNO ...
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] More detailed structure comparisons have revealed that tensins 1-3, PTEN , auxilin [ 5 ] and other proteins in animals, plants and fungi comprise a PTP-C2 ...
Phosphoinositide 3-kinases (PI3Ks), also called phosphatidylinositol 3-kinases, are a family of enzymes involved in cellular functions such as cell growth, proliferation, differentiation, motility, survival and intracellular trafficking, which in turn are involved in cancer.
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]

PTEN chromosomal location is 10q23.31, while the molecular location is 87,863,438 to 87,971,930 [2] [7] There are many syndromes that are linked to PTEN aside from Bannayan–Riley–Ruvalcaba Syndrome. [8] The syndrome combines Bannayan–Zonana syndrome, Riley–Smith syndrome, and Ruvalcaba–Myhre–Smith syndrome. [9]
