Biochem/physiol Actions
PDK1 (3-phosphoinositide-dependent protein kinase) is activated by the presence of PtdIns (3, 4, 5) P3 or PtdIns (3, 4) P2. PDK1 then activates protein kinase B (PKB) which, in turn, inactivates glycogen synthase kinase-3 (GSK3). The phosphorylation of other proteins by PKB and GSK3 is likely to mediate many of the intracellular actions of insulin. Thus, PDK1 plays a key role in mediating many of the actions of the second messenger(s) PtdIns (3, 4, 5) P3 and/or PtdIns (3, 4) P2. The human PDK1 is a 556-residue monomeric enzyme comprising of a catalytic domain that is most similar to the PKA, PKB and PKC subfamily of protein kinases.
PDPK1 (3-phosphoinositide dependent protein kinase 1) is a serine/threonine protein kinase which is activated upon accumulation of PIP3 (phosphatidylinositol-3,4,5-trisphosphate), a PI3K (phosphoinositide 3-kinase) product. It controls AGC (protein kinase A, G, and C) kinase members, such as AKT (v-akt murine thymoma viral oncogene homolog), p70 ribosomal S6 kinase (S6K), serum- and glucocorticoid-induced protein kinase (SGK), and protein kinase C (PKC) members. It is involved in metabolism, growth, proliferation, and survival. PDPK1 is associated with growth of angiosarcoma cells.

PDK1 is a master kinase that activates at least six protein kinase groups including AKT, PKC and S6K and is a potential target in the treatment of a range of malignancies. Here we show overexpression of PDK1 in over 40%

Angiosarcoma is a rare and aggressive malignant neoplasm of endothelial cells. Recent studies have shown that the mTOR pathway is also aberrantly activated in cutaneous angiosarcoma. New therapeutic strategies are required because the prognosis of this disease is still poor.

Although 3-phosphoinositide-dependent protein kinase-1 (PDK1) has been predominately linked to the phosphoinositide 3-kinase (PI3K)-AKT pathway, it may also evoke additional signaling outputs to promote tumorigenesis. Here, we report that PDK1 directly induces phosphorylation of Polo-like kinase 1 (PLK1), which in

The initial steps in insulin signal transduction occur at the plasma membrane and lead to the activation of phosphatidylinositide (PtdIns) 3-kinase and the formation of PtdIns(3,4,5,)P3 in the inner leaflet of the plasma membrane which is then converted to PtdIns(3,4)P2

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
