Function

FUNCTION: Tumor suppressor. Acts as a dual-specificity protein phosphatase, dephosphorylating tyrosine-, serine- and threonine- phosphorylated proteins. Also acts as a lipid phosphatase, removing the phosphate in the D3 position of the inositol ring from phosphatidylinositol 3,4,5-trisphosphate, phosphatidylinositol 3,4-diphosphate, phosphatidylinositol 3- phosphate and inositol 1,3,4,5-tetrakisphosphate with order of substrate preference in vitro PtdIns(3,4,5)P3 > PtdIns(3,4)P2 > PtdIns3P > Ins(1,3,4,5)P4 (PubMed:26504226). The lipid phosphatase activity is critical for its tumor suppressor function. Antagonizes the PI3K-AKT/PKB signaling pathway by dephosphorylating phosphoinositides and thereby modulating cell cycle progression and cell survival. The unphosphorylated form cooperates with AIP1 to suppress AKT1 activation. Dephosphorylates tyrosine-phosphorylated focal adhesion kinase and inhibits cell migration and integrin-mediated cell spreading and focal adhesion formation. Plays a role as a key modulator of the AKT-mTOR signaling pathway controlling the tempo of the process of newborn neurons integration during adult neurogenesis, including correct neuron positioning, dendritic development and synapse formation. May be a negative regulator of insulin signaling and glucose metabolism in adipose tissue. The nuclear monoubiquitinated form possesses greater apoptotic potential, whereas the cytoplasmic nonubiquitinated form induces less tumor suppressive ability. In motile cells, suppresses the formation of lateral pseudopods and thereby promotes cell polarization and directed movement. {ECO:0000269|PubMed:26504226}.;

Disease

DISEASE: Cowden syndrome 1 (CWS1) [MIM:158350]: An autosomal dominant hamartomatous polyposis syndrome with age-related penetrance. Cowden syndrome is characterized by hamartomatous lesions affecting derivatives of ectodermal, mesodermal and endodermal layers, macrocephaly, facial trichilemmomas (benign tumors of the hair follicle infundibulum), acral keratoses, papillomatous papules, and elevated risk for development of several types of malignancy, particularly breast carcinoma in women and thyroid carcinoma in both men and women. Colon cancer and renal cell carcinoma have also been reported. Hamartomas can be found in virtually every organ, but most commonly in the skin, gastrointestinal tract, breast and thyroid. {ECO:0000269|PubMed:10051160, ECO:0000269|PubMed:10234502, ECO:0000269|PubMed:10400993, ECO:0000269|PubMed:10866302, ECO:0000269|PubMed:11230179, ECO:0000269|PubMed:11494117, ECO:0000269|PubMed:15355975, ECO:0000269|PubMed:18716620, ECO:0000269|PubMed:9140396, ECO:0000269|PubMed:9241266, ECO:0000269|PubMed:9259288, ECO:0000269|PubMed:9345101, ECO:0000269|PubMed:9399897, ECO:0000269|PubMed:9425889, ECO:0000269|PubMed:9467011, ECO:0000269|PubMed:9600246, ECO:0000269|PubMed:9735393, ECO:0000269|PubMed:9797362, ECO:0000269|PubMed:9811831, ECO:0000269|PubMed:9832031, ECO:0000269|PubMed:9915974}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Lhermitte-Duclos disease (LDD) [MIM:158350]: A rare disease characterized by the occurrence of a slowly enlarging mass within the cerebellar cortex corresponding histologically to a cerebellar hamartoma. It manifests, most commonly in the third and fourth decades of life, with increased intracranial pressure, headache, nausea, cerebellar dysfunction, occlusive hydrocephalus, ataxia, visual disturbances and other cranial nerve palsies. Various associated abnormalities may be present such as megalencephaly, microgyria, hydromyelia, polydactyly, partial gigantism, macroglossia. LDD is part of the PTEN hamartoma tumor syndromes spectrum that also includes Cowden syndrome. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Squamous cell carcinoma of the head and neck (HNSCC) [MIM:275355]: A non-melanoma skin cancer affecting the head and neck. The hallmark of cutaneous SCC is malignant transformation of normal epidermal keratinocytes. {ECO:0000269|PubMed:11801303}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Endometrial cancer (ENDMC) [MIM:608089]: A malignancy of endometrium, the mucous lining of the uterus. Most endometrial cancers are adenocarcinomas, cancers that begin in cells that make and release mucus and other fluids. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.; DISEASE: Note=PTEN mutations are found in a subset of patients with Proteus syndrome, a genetically heterogeneous condition. The molecular diagnosis of PTEN mutation positive cases classifies Proteus syndrome patients as part of the PTEN hamartoma syndrome spectrum. As such, patients surviving the early years of Proteus syndrome are likely at a greater risk of developing malignancies.; DISEASE: Glioma 2 (GLM2) [MIM:613028]: Gliomas are benign or malignant central nervous system neoplasms derived from glial cells. They comprise astrocytomas and glioblastoma multiforme that are derived from astrocytes, oligodendrogliomas derived from oligodendrocytes and ependymomas derived from ependymocytes. {ECO:0000269|PubMed:12085208}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.; DISEASE: Prostate cancer (PC) [MIM:176807]: A malignancy originating in tissues of the prostate. Most prostate cancers are adenocarcinomas that develop in the acini of the prostatic ducts. Other rare histopathologic types of prostate cancer that occur in approximately 5% of patients include small cell carcinoma, mucinous carcinoma, prostatic ductal carcinoma, transitional cell carcinoma, squamous cell carcinoma, basal cell carcinoma, adenoid cystic carcinoma (basaloid), signet-ring cell carcinoma and neuroendocrine carcinoma. {ECO:0000269|PubMed:26504226, ECO:0000269|PubMed:9072974}.
