Antibody Immunogen Source: Human PTEN sequence peptide Cat. No.: PE-01BBN90
Antibody Immunogen Sequence: CSPNFKVKLYFTKTVE
Antibody Immunogen Description: Corresponds to amino acid residues S338 to E352
Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.

Scientific Background: PTEN is a dual-specificity protein phosphatase, dephosphorylating tyrosine-, serine- and threonine-phosphorylated proteins, and 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. The lipid phosphatase activity is critical for the tumor suppressor function of PTEN. It antagonizes the PI3K-AKT/PKB signalling pathway by dephosphorylating phosphoinositides, and inhibits cell cycle progression and cell survival. The unphosphorylated form of PTEN cooperates with AIP1 to suppress Akt1 activation. It dephosphorylates tyrosine-phosphorylated focal adhesion kinase (FAK) and inhibits cell migration and integrin-mediated cell spreading and focal adhesion formation. It plays a role as a key modulator of the AKT-mTOR signalling pathway controlling the tempo of the process of newborn neurons integration during adult neurogenesis. It acts as negative regulator of insulin signalling 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, PTEN suppresses the formation of lateral pseudopods and thereby promotes cell polarization and directed movement.
