Background InformationPhosphatidylinositol 3,4,5-trisphosphate 3-phosphatase and dual-specificity protein phosphatase PTEN (UniProt: P60484; also known as Mutated in multiple advanced cancers 1, Phosphatase and tensin homolog, PTEN) is encoded by the PTEN (also known as MMAC1, TEP1) gene (Gene ID: 5728) in human. PTEN belongs to the family of lipid phosphatases. It contains an N-terminal phosphatase catalytic domain, a C2-domain that binds to phospholipid membranes, and a C-terminal regulatory tail. It is a dual-specific phosphatase, which dephosphorylates both lipid and protein substrates. PTEN blocks the phosphatidylinositol 3-kinase/Akt signaling pathway by removing the phosphate in the 3-position on phosphoinositide-3, 4, 5-trisphosphate (PIP3). Dephosphorylation of PIP3 is an important factor in cell growth, proliferation, apoptosis, and survival. Dephosphorylation of PIP3 blocks Akt signaling that can lead to higher activity of pro-apoptotic molecules such as Bad and Caspase-9. PTEN activity, stability, localization, and conformation are controlled through complex regulatory mechanisms, including the reversible phosphorylations of several Serine/Threonine residues in its unfolded C-terminal tail region (PTEN-C-tail, residues 351-403). Alternative translation of PTEN is reported to encode a 576-amino acid translational variant that is known as PTEN-Long with a 173-amino acid domain at its N-terminus followed by the classical 403 amino acids of PTEN. PTEN-Long is a membrane permeable, secreted protein that can enter other cells and acts as an antagonist of the PI3K pathway. PTEN is considered a major tumor suppressor and its mutations are reported in several human tumors. Over seventy different types of PTEN mutation have been recorded in patients with Cowden syndrome. PTEN -/- mice exhibit higher levels of 3 -phosphorylated phospholipids and die during embryogenesis due to the failure of developmental apoptosis. Clone 1A1 captures both PTEN and PTEN-Long and can be used both as capture and detection antibody. (Ref.: Hopkins, BD., et al. (2013). Science. 341(6144); 399-402).
