Part Description

LP212218-4   Phosphatidylinositol 3,4,5-trisphosphate 3-phosphatase and dual-specificity protein phosphatase PTEN
Phosphatidylinositol 3,4,5-trisphosphate 3-phosphatase and dual-specificity protein phosphatase PTEN, also known as phosphate and tensin homolog or PTEN protein, is encoded by the PTEN gene on chromosome10q23.31. PTEN protein has multiple functions, including protein phosphatase and lipid phosphatase activity. The lipid phosphatase function is critical for its role as a tumor suppressor and modulating cell cycle progression and cell survival. It also plays a role in correct neuron positioning, dendritic development and synapse formation, and may be a negative regulator of insulin signaling and glucose metabolism in adipose tissue. Mutations in the PTEN gene are associated with multiple disorders, including PTEN hamartoma tumor syndromes, which include Cowden syndrome and Lhermitte-Duclos disease, squamous cell carcinoma of the head and neck, endometrial carcinoma, prostate cancer, and VACTERL with hydrocephalus. [UniProt: P60484] Loss of the PTEN gene can be determined by various techniques, including FISH, and loss of the PTEN protein can be detected by immunohistochemistry techniques.
