product name 740 Y-P (PDGFR 740Y-P)
Description: 740 Y-P is a potent cell-permeable phosphopeptide activator of PI3K. 740 Y-P plays an important role in PI3K/AKT signaling pathway. When tested with human melanoma MNT-1 cells, 20 μM 740 Y-P for 24 hours treatment significantly reduced the number of M6PR-positive vacuoles induced by sucrose via activating PI3K. In cerebellar granule cells in the circumstance of serum deprivation, 740 Y-P treatments reduced the cell death rate via binding to p85 which was correlated with PI 3-kinase-dependent phosphorylation of Akt process.

In vitro activity: The PDGFR 740Y-P peptide stimulates a mitogenic response in muscle cells. The ability of the 740Y-P peptide to stimulate mitogenesis is highly specific and not a general feature of a cell permeable SH2 domain binding peptides. 740Y-P is as effective as a growth factor (FGF2) at promoting neuronal cell survival via the established PI 3-kinase-Akt survival cascade. Stimulation of neuronal cell survival by the PDGFR740Y-P peptide is dose dependent and does not require insulin. Kinase Assay: 740 Y-P is an activator of PI3K with concentration of 20 μM. Cell Assay: NIH 3T3 cells (2×106) are incubated in suspension at 37°C in Ca2+ and Mn2+ free HBSS, 10% FCS containing either 50 μg/ml of 740Y-P peptide or an equal volume of PBS as a control. After 2h cells are centrifuged, washed and trypsinised to degrade non-internalised peptide. Cells are then resuspended in lysis buffer (50 mM Tris pH 7.4, 150 mM NaCl, 10% Glycerol, 2% NP40, 0.25% deoxycholate, 1 mM EDTA, 1 mM Vanadate, Protease inhibitors “complete” cocktail from Boehringer-Mannheim) for 1 h at 4°C. Lysates are clarified by centrifugation at 1.4×104g for 5 min and the supernatants are incubated for 1h with streptavidin-agarose beads. Beads are subsequently washed three times in lysis buffer and finally boiled in SDS sample buffer and resolved by SDS-PAGE on a 12% gel, transferred to nitrocellulose and immunoblotted with the p85 monoclonal antibody. |
