Description General description Akt is the major known effector of the PI3 Kinase pathway. Generation of PIP3 results in the activation of PDK1, which phosphorylates Akt on Thr308, and another kinase complex, thought to be the mTORC2 complex (or possibly an intermediate kinase linking the two) that phosphorylates Akt on Ser473. These phosphorylations additively activate Akt Ser/Thr kinase activity, and the use of phosphorylation state-specific antibodies directed against either of these sites can imply Akt activation. Activation of Akt can be measured directly by immunoprecipitation followed by phosphorylation of a known substrate with radiolabeled ATP. Akt has been shown to phosphorylate over 70 substrates including TSC1&2 in the mTOR pathway, Bad on Ser136, GSK3, which is inactivated by this phosphorylation, the FoxO family of transcription factors, PRAS40, AS160. Specificity Recognizes Akt1/PKBα, MW ~60 kDa. Immunogen 15 residue synthetic peptide (C-RPHFPQFS YSASGTA) corresponding to the C-terminal (residues 466-480) of rat Akt1, with an N-terminal cysteine added for conjugation purposes. The Akt1 sequence is identical to mouse Akt1 (15/15 amino acids) and strongly conserved in bovine Akt1 (14/15 amino acids) and human Akt1 (13/15 amino acids). Human Akt2 shares 11/15 amino acids with the peptide immunogen sequence. Epitope: C-terminus Application Immunoprecipitation Kinase Assay: 4 µg of a previous lot immunoprecipitated active Akt from 1 mg of HEK293 cells stimulated with IGF-1.
