Akt2-b is one of several closely related serine/threonine-protein kinases known as the AKT kinase, and which regulate many processes including metabolism, proliferation, cell survival, growth and angiogenesis. This is mediated through serine and/or threonine phosphorylation of a range of downstream substrates. Over 100 substrate candidates have been reported so far, but for most of them, no isoform specificity has been reported. May be involved in the inhibition of ciliogenesis
