Molecular mechanism for the regulation of protein kinase B/Akt by hydrophobic motif phosphorylation.
Protein kinase B/Akt plays crucial roles in promoting cell survival and mediating insulin responses. The enzyme is stimulated by phosphorylation at two regulatory sites: Thr 309 of the activation segment and Ser 474 of the hydrophobic motif, a conserved feature of many AGC kinases. Analysis of the crystal structures of the unphosphorylated and Thr 309 phosphorylated states of the PKB kinase dom...
متن کاملRegulation of Protein Kinase
We have used a permeabilized cell assay and a synthetic peptide substrate (KRTLRR) to specifically monitor the activity of protein kinase C in PC12 cells preincubated with nerve growth factor (NGF), epidermal growth factor (EGF), or phorbol esters. Pretreatment of PC12 cells with 1 PM 12-0-tetradecanoylphorbo1 13-acetate or 1 I.~M phorbol dibutyrate stimulated the rate of KRTLRR peptide phospho...
متن کاملRegulation 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...
متن کاملRegulation of protein kinase C.
Protein kinase C has been in the spotlight since the discovery two decades ago that it is activated by the lipid second messenger diacylglycerol. Despite protein kinase C's enduring stage presence, the regulation and specific roles of its isozymes in defined cellular processes are still under intense investigation. Elucidation of the structures of protein kinase C's regulatory modules, the disc...
متن کاملProtein kinase C: structure, function, and regulation.
The protein kinase C family of enzymes transduces the myriad of signals promoting lipid hydrolysis. The prevalence of this enzyme family in signaling is exemplified by the diverse transduction mechanisms that result in the generation of protein kinase C's activator, diacylglycerol. Signals that stimulate members of the large families of G protein-coupled receptors, tyrosine kinase receptors, or...
