Although PKB has many down stream targets which may regulate these effects [ 47] a key target of PKB is GSK3β [ 29].
PtdIns(3,4)P2 and PtdIns(3,4,5)P3 recruit AKT (also known as protein kinase B [PKB]) to the membrane through the N-terminal pleckstrin homology (PH) domain of AKT [reviewed in ref.
First, PTEN's protein phosphatase activity is able to down-regulate focal adhesion kinase (FAK) phosphorylation, which leads to the inactivation of the Ras/MAP kinase pathway [ 19 20 21 ] . Second, its lipid phosphatase activity targets the second messenger phosphatidylinositol 3,4,5-trisphosphate [PtdIns(3,4,5)P 3 ] and thereby blocks activation of the protein kinase B (PKB/Akt) pathway [ 11 18 22 23 24 ] . Whereas both of the above pathways are intimately involved in the control of cell growth and survival, PTEN-regulated FAK activity further appears to impinge on cell adhesion, cell migration, and cell invasion [ 20 21 ] . It therefore emerges that the loss of PTEN activity may confer increased survival ability, proliferative potential, and invasive capacity on cells, and thereby may promote progression towards a more malignant phenotype.
Phosphorylation of GSK3β by PKB inhibits GSK3β kinase activity [ 29].
