Protein Name Phosphatidylinositol 3,4,5-trisphosphate 3-phosphatase and dual-specificity protein phosphatase PTEN (EC 3.1.3.16) (EC 3.1.3.48) (EC 3.1.3.67) (Mutated in multiple advanced cancers 1) (Phosphatase and tensin homolog)
Gene Name PTEN; MMAC1; TEP1
Organism Homo sapiens
NCBI Taxa ID 9606
Functional DescriptionTumor 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).

NumPTMDiseaseCell TypeTypePTM SitePMID
1MethylationAcute lymphoblastic leukaemiaD24273277
[Reference]: the methylation levels of PTEN gene in the co-infected group were significantly decreased (P<0.05) while the methylation levels of hTERT gene significantly increased (P<0.05)
2MethylationGlioblastomaD23977117; 3747204
[Reference]: The nTBVs of the MGMT methylation-negative group (mean 9.5?7.5) were significantly higher than those of the MGMT methylation-positive group (mean 5.4?1.8) (p=.046). In the analysis of EGFR expression-positive group, the nTBVs of the subgroup with loss of PTEN gene expression (mean: 10.3?8.1) were also significantly higher than those of the subgroup without loss of PTEN gene expression (mean: 5.6?2.3) (p=.046). Ki-67 labeling index indicated significant positive correlation with the nTBV of the tumor (p=.01)
3PhosphorylationAcute myeloid leukaemia/Acute myelogenous leukemiaP15297415
[Reference]: Elevated S-phase kinase-associated protein 2 protein expression in acute myelogenous leukemia: its association with constitutive phosphorylation of phosphatase and tensin homologue protein and poor prognosis.
4PhosphorylationFibromyomatous uteriU17097286
[Reference]: Phosphorylation of PTEN (phosphatase and tensin homologue deleted on chromosome ten) protein is enhanced in human fibromyomatous uteri.
5PhosphorylationLymphocytic leukemiaU20660292; 24278390
[Reference]: recent studies have demonstrated that phosphorylation levels of PTEN are significantly higher in malignant leukemia cells than in normal B cells; Although isolated malignant B cells collected from CLL patients and purified normal B cells from age-matched healthy controls presented similar PTEN protein expression levels, we found that CLL cells displayed significantly higher phosphorylated PTEN than normal controls
6MethylationOvarian cancer/carcinomaU23933187
[Reference]: We demonstrated that intratumoral injection of Chi-29b chimera significantly inhibited the growth of xenograft OVCAR-3 tumors through downregulating PTEN methylation
7PhosphorylationGlioblastomaC24346432
[Reference]: EGFR phosphorylation was increased only in LCM-enriched tumor specimens carrying EGFR mutations. Phosphorylated and total PTEN, which is highly expressed in normal brain, was reduced only in LCM-enriched tumor specimens with either PTEN mutation or loss in PTEN copy number, with no differences observed in non-microdissected samples.
8Tyrosine PhosphorylationGlioblastomatumor tissuePY24022891331
[Reference]: Here we demonstrate that the phosphatase and tensin homolog deleted on chromosome 10 (PTEN) tumor suppressor is frequently phosphorylated at a conserved tyrosine residue, Y240, in GBM clinical samples
9Tyrosine PhosphorylationGlioblastomaUY24022891331
[Reference]: Phosphorylation of Y240 is associated with shortened overall survival and resistance to EGFR inhibitor therapy in GBM patients and plays an active role in mediating resistance to EGFR inhibition in vitro.
10Serine PhosphorylationLymphocytic leukemiaUS37020576813
[Reference]: However, PTEN was highly phosphorylated at Ser-370, Ser-380, Thr-382, and Ser-385 in CLL samples, whereas PTEN phosphorylation at these sites was minimal or undetectable in healthy donor samples
11Serine PhosphorylationLymphocytic leukemiaUS38020576813
[Reference]: However, PTEN was highly phosphorylated at Ser-370, Ser-380, Thr-382, and Ser-385 in CLL samples, whereas PTEN phosphorylation at these sites was minimal or undetectable in healthy donor samples
12Serine PhosphorylationGastric cancerGES-1 cellsUS38022521126
[Reference]: Moreover, further analysis of data on Western blots revealed that the PTEN phosphorylation and PTEN ratio was higher in gastric cancer cell lines than that of non-malignant GES-1 cells
13Threonine PhosphorylationLymphocytic leukemiaUT38220576813
[Reference]: However, PTEN was highly phosphorylated at Ser-370, Ser-380, Thr-382, and Ser-385 in CLL samples, whereas PTEN phosphorylation at these sites was minimal or undetectable in healthy donor samples
14Serine PhosphorylationLymphocytic leukemiaUS38520576813
[Reference]: However, PTEN was highly phosphorylated at Ser-370, Ser-380, Thr-382, and Ser-385 in CLL samples, whereas PTEN phosphorylation at these sites was minimal or undetectable in healthy donor samples
