Signaling lipid; activates PDK1 (3-phosphoinositide-dependent protein kinase), which is necessary, but not sufficient, for the activation of PKB/Akt. PDK1 also phosphorylates and activates p70S6k.

Protein kinase B (PKB) is a proto-oncogene that is activated in signaling pathways initiated by phosphoinositide 3-kinase. Chromatographic separation of brain cytosol revealed a kinase activity that phosphorylated and activated PKB only in the presence of phosphatidylinositol-3,4,5-trisphosphate [PtdIns(3,4,5)P3]. Phosphorylation occurred

The activation of protein kinase B (PKB, also known as c-Akt) is stimulated by insulin or growth factors and results from its phosphorylation at Thr308 and Ser473. We recently identified a protein kinase, termed PDK1, that phosphorylates PKB at Thr308

Protein kinase B (PKB), also known as c-Akt, is activated rapidly when mammalian cells are stimulated with insulin and growth factors, and much of the current interest in this enzyme stems from the observation that it lies 'downstream' of phosphoinositide

The p70 S6 kinase, an enzyme critical for cell-cycle progression through the G1 phase, is activated in vivo by insulin and mitogens through coordinate phosphorylation at multiple sites, regulated by signaling pathways, some of which depend on and some of
