Akt (protein kinase B), a serine/threonine kinase, has emerged as a critical enzyme in signal transduction pathways involved in cell proliferation, apoptosis, angiogenesis, and diabetes. In mammals three isoforms of Akt (α, β, γ or Akt 1, 2, 3) are reported that exhibit a high degree of homology, but differ slightly in the localization of their regulatory phosphorylation sites. Akt α is the predominant isoform in most tissues, whereas the highest expression of Akt β is observed in the insulin-responsive tissues, and Akt γ is abundant in brain tissue. Each Akt isoform is composed of three functionally distinct regions: an N-terminal pleckstrin homology (PH) domain that provides a lipid-binding module to direct Akt to PIP2 and PIP3, a central catalytic domain, and a C-terminal hydrophobic motif.
