Protein phosphorylation in pancreatic islets induced by 3-phosphoglycerate and 2-phosphoglycerate.
We have shown previously that 3-phosphoglycerate, which is a glycolytic metabolite of glucose, induces protein phosphorylation in bovine and rat brain and in rat heart, kidney, liver, lung, and whole pancreas. Since glycolytic metabolism of glucose is of paramount importance in insulin release, we considered the possibility that 3-phosphoglycerate may act as a coupling factor, and we searched f...
متن کاملPhosphorylation-dependent 14-3-3 protein interactions regulate CFTR biogenesis
Cystic fibrosis transmembrane conductance regulator (CFTR) is a cAMP/protein kinase A (PKA)-regulated chloride channel whose phosphorylation controls anion secretion across epithelial cell apical membranes. We examined the hypothesis that cAMP/PKA stimulation regulates CFTR biogenesis posttranslationally, based on predicted 14-3-3 binding motifs within CFTR and forskolin-induced CFTR expression...
متن کاملPhosphatidate-dependent protein phosphorylation.
Phosphatidate-dependent protein phosphorylation was observed in soluble extracts from rat liver, brain, lung, and testis. The phosphorylation was stimulated by free Ca2+ in the range of 360-800 nM. Incubation mixtures containing phosphatidate provided markedly different profiles of protein phosphorylation from those with phosphatidylserine plus 1,2-diolein. Phosphatidate-dependent phosphorylati...
متن کاملPhosphorylation-Dependent Protein Interaction with Trypanosoma brucei 14-3-3 Proteins that Display Atypical Target Recognition
BACKGROUND The 14-3-3 proteins are structurally conserved throughout eukaryotes and participate in protein kinase signaling. All 14-3-3 proteins are known to bind to evolutionally conserved phosphoserine-containing motifs (modes 1 and/or 2) with high affinity. In Trypanosoma brucei, 14-3-3I and II play pivotal roles in motility, cytokinesis and the cell cycle. However, none of the T. brucei 14-...
متن کاملMultisite phosphorylation of 14-3-3 proteins by calcium-dependent protein kinases.
Plant 14-3-3 proteins are phosphorylated at multiple sites in vivo; however, the protein kinase(s) responsible are unknown. Of the 34 CPK (calcium-dependent protein kinase) paralogues in Arabidopsis thaliana, three (CPK1, CPK24 and CPK28) contain a canonical 14-3-3-binding motif. These three, in addition to CPK3, CPK6 and CPK8, were tested for activity against recombinant 14-3-3 proteins χ and ...
