WebA key downstream effector of Ptd (3,4,5)P3 is AKT, which is recruited to the plasma membrane. Activation of AKT also requires the protein kinase 3-phosphoinositide-dependent protein kinase-1 (PDK1), which, combined with an as-yet unidentified kinase, leads to the phosphorylation of AKT (Fig. 1).
