We have searched for phosphatidylinositol (PI)-3,4,5-trisphosphate (PIP3) binding proteins in Dictyostelium discoideum using beads bearing a PIP3 analogue, PIP3-APB. One of the binding proteins with a molecular mass of 55 kDa was purified and its amino acid sequence was partially analyzed. Database searches showed that the analyzed sequence was identical to that of protein kinase B (PKB) of D. ...

Recent evidence for cross-talk between protein kinase B (PKB) and the Raf-1 and NF-kappaB signalling pathways has provided new hints to the complex roles that PKB may play in regulating gene transcription and also raised questions about where and when these targets are relevant.

BACKGROUND/AIMS Human ether-a-go-go (hERG) channels contribute to cardiac repolarization and participate in the regulation of tumor cell proliferation. Mutations in hERG channels may cause long QT syndrome and sudden cardiac death due to ventricular arrhythmias. HERG channel activity is up-regulated by the serum- and glucocorticoid-inducible kinase isoforms SGK1 and SGK3. Related kinases are pr...

OBJECTIVE Ceramide is now recognized as a negative regulator of insulin signaling by impairing protein kinase B (PKB)/Akt activation. In different cells, two distinct mechanisms have been proposed to mediate ceramide inhibition of PKB/Akt: one involving atypical protein kinase C zeta (PKCzeta) and the other the protein phosphatase-2 (PP2A). We hypothesized that ceramide action through PKCzeta o...

The PtdIns(3,4,5)P3-dependent activation of protein kinase B (PKB) by 3-phosphoinositide-dependent protein kinases-1 and -2 (PDK1 and PDK2 respectively) is a key event in mediating the effects of signals that activate PtdIns 3-kinase. The catalytic domain of serum- and glucocorticoid-regulated protein kinase (SGK) is 54% identical with that of PKB and, although lacking the PtdIns(3,4, 5)P3-bind...

Podocytes or glomerular epithelial cells (GECs) are important targets of the diabetic microenvironment. Podocyte foot process effacement and widening, loss of GECs and hypertrophy are pathological features of this disease. ANG II and oxidative stress are key mediators of renal hypertrophy in diabetes. The cellular mechanisms responsible for GEC hypertrophy in diabetes are incompletely character...

The leukemic T cell line Jurkat is deficient in protein expression of the lipid phosphatases Src homology 2 domain containing inositol polyphosphate phosphatase (SHIP) and phosphatase and tensin homolog deleted on chromosome ten (PTEN). We examined whether the lack of expression of SHIP-1 and PTEN is shared by other leukemic T cell lines and PBLs. Analysis of a range of cell lines and PBLs reve...
