Mechanism of protein kinase B activation by cyclic AMP-dependent protein kinase.

Activation of protein kinase B (PKB) by growth factors and hormones has been demonstrated to proceed via phosphatidylinositol 3-kinase (PI3-kinase). In this report, we show that PKB can also be activated by PKA (cyclic AMP [cAMP]-dependent protein kinase) through a PI3-kinase-independent pathway. Although this activation required phosphorylation of PKB, PKB is not likely to be a physiological s...

by cyclic AMP-dependent protein kinase

Myosin light-chain kinase was purifed from bovine carotid artery. Approx. 90% of myosin kinase was extracted in the supernatant fraction with buffer containing EDTA during myofibril preparation. The soluble fraction yielded two distinct peaks on DEAE-Sephacel chromatography. Peak I was eluted at a conductance of 11-12mmho and was completely dependent on Ca2+-calmodulin for its activity. Peak II...

Ezrin is a cyclic AMP-dependent protein kinase anchoring protein.

cAMP-dependent protein kinase (A-kinase) anchoring proteins (AKAPs) are responsible for the subcellular sequestration of the type II A-kinase. Previously, we identified a 78 kDa AKAP which was enriched in gastric parietal cells. We have now purified the 78 kDa AKAP to homogeneity from gastric fundic mucosal supernates using type II A-kinase regulatory subunit (RII) affinity chromatography. The ...

Regulation of autophagy by AMP-activated protein kinase/ sirtuin 1 pathway reduces spinal cord neurons damage

Objective(s): AMP-activated protein kinase/sirtuin 1 (AMPK/SIRT1) signaling pathway has been proved to be involved in the regulation of autophagy in various models. The aim of this study was to evaluate the effect of AMPK/SIRT1 pathway on autophagy after spinal cord injury (SCI). Materials and Methods:The SCI model was established in rats in vivo and the primary spinal cord neurons were subject...
