Abstract:
Ten years ago, it was observed that the Akt kinase is activated by phosphorylation via a phosphoinositide 3-kinase (PI-3K)-dependent process. This discovery generated enormous interest because it provided a link between PI-3K, an enzyme known to play a critical role in cellular physiology, and its downstream targets. Subsequently, it was shown that the activity of the core components of the 'PI-3K/Akt pathway' is modulated by a complex network of regulatory proteins and pathways. Some of the Akt-binding partners modulate its activation by external signals by interacting with different domains of the Akt protein. This review focuses on the Akt interacting proteins and the mechanisms by which they regulate Akt activation.
