Akt Antibody (Phospho-Ser473), pAb, Rabbit

USA

Rabbit Anti-Akt (Phospho-Ser473) detects endogenous human, mouse, and rat Akt1, Akt2 and Akt3, phosphorylated at serine 473, serine 474, and serine 472, respectively.

Akt, also known as protein kinase B (PKB), a serine/ threonine kinase, is a critical enzyme in several signal transduction pathways involved in cell proliferation, apoptosis, angiogenesis, and diabetes. Akt is activated following its phosphorylation at two regulatory residues. Phosphorylation of threonine on the kinase domain, catalyzed by PDK1, is essential for Akt activation. Akt activity is augmented approximately ten fold by phosphorylation at the serine on the hydrophobic motif by PDK2. Phosphorylation of Thr308 and Ser473 activates Akt alpha. Phosphorylation at Thr309 and Ser474 on Akt beta1 and beta2, and on Thr305 on Akt gamma results in their activation. Akt promotes cell survival by inhibiting apoptosis by phosphorylating and inactivating several targets, including bad, forkhead transcription factors, c-Raf and caspase-9. The activation of Akt is negatively regulated by PTEN, a PIP3-specific phosphatase, and SHIP, a SH2-domain containing inositol 5-phosphatase. GenScript, Rabbit Anti-Akt (Phospho-Ser473) Polyclonal Antibody, is developed in rabbit using a synthetic phosphopeptide corresponding to residues surrounding S473 of human, rat, and mouse Akt alpha, also known as Protein Kinase B alpha (PKBalpha), Akt1, and RACalpha. In addition, this phosphopeptide is identical to the sequence surrounding S474 of human, rat, and mouse Akt beta (Akt2) and S472 of human and mouse Akt gamma (Akt3).

GenScript Rabbit Anti-Akt (Phospho-Ser473) Polyclonal Antibody is purified from rabbit antiserum by affinity chromatography using epitope-specific phosphopeptide and cross-adsorbed with the corresponding non-phosphopeptide.
