Mechanism of activation and function of protein kinase B

Curr Opin Genet Dev. 1998 Feb;8(1):55-62. doi: 10.1016/s0959-437x(98)80062-2.

Abstract

The past year has seen significant advances in our understanding of how protein kinase B (PKB) is activated and of the central role it plays in insulin signalling and in mediating the protective effects of survival factors against apoptosis. The highlights include the discovery of a protein kinase required for the 3-phosphoinositide-dependent activation of PKB and the identification of several physiological substrates for PKB.
