Akt, also known as Protein Kinase B (PKB) and Rac (Related to the A and C kinases), is a 60kD serine/threonine kinase critical for controlling diverse cellular functions, including glucose metabolism, gene transcription, cell proliferation, and apoptosis.
Akt phosphorylates a number of physiological substrates including MBP, glycogen synthetase, PKA RII subunit, and histone H1.
Akt is activated in response to insulin and growth factors in a PI3-kinase dependent manner.
Activation of PI3-Kinase generates phosphatidylinositol 3,4-bisphosphate which may induce the membrane translocation of Akt coincident with its phosphorylation and activation.
Upon activation, Akt associates with members of the PKC family of kinases, such as PKCd and PKCz.
Ceramide-activated PKCz leads to phosphorylation of the Akt-Pleckstrin Homology (PH) domain on threonine 34.
This phosphorylation inhibits PIP3 binding to Akt, preventing activation of the kinase by insulin.
Since Akt confers a prosurvival signal and regulates pathways in response to insulin, suppressing its activation may be one mechanism by which ceramide promotes cell death and induces insulin resistance.
