Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human Akt1 (PKBa) sequence peptide Cat. No.: PE-04AIE70

Antibody Immunogen Sequence: TMK(pT)FCG(bA)C

Antibody Immunogen Description: Corresponds to amino acid residues T305 to G311; In protein kinase catalytic domain activation T-loop between subdomains VII and VIII.

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.This antibody was also subject to negative purification over phosphotyrosine-agarose.

Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: Akt1 (PKBA) is a protein-serine/threonine kinase of the AGC group and Akt family. It is normally inactive in the cytoplasm. When PI3K is activated by extracellular growth factors, Akt1 is recruited to the cell membrane and phosphorylated by PDK1, mTOR and other protein kinases to become active. This leads to the induction of survival, proliferation, angiogenesis and metabolism pathways. Akt1 is also involved in cell-cycle progression via its inhibitory phosphorylation of cyclin-dependent kinases and activatory phosphorylation of mTOR. This kinase is highly expressed in most tested human tissues. Orthologues of Akt are conserved in a wide range of animals, plants and unicellular eukaryotes. Phosphorylation of T72, S124,S129, S246, T308, Y315,Y326, T450, S473 and Y474 increases Akt1 phosphotransferase activity. TRAF6-induced 'K63'-linked Akt1 ubiquitination is critical for phosphorylation and activation. Phosphorylation of T34 inhibits phosphotransferase activity. Akt1 has been implicated in a wide range of human cancers, including lymphomas, breast, lung, colorectal, pancreatic and prostate cancers.
