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.
