Regulation of choline transporter surface expression and phosphorylation by protein kinase C and protein phosphatase 1/2A.
The Na(+)/Cl(-)-dependent, hemicholinium-3-sensitive choline transporter (CHT) provides choline for acetylcholine biosynthesis. Recent studies show that CHT contains canonical protein kinase C (PKC) serine and threonine residues. We examined the ability of PKC and serine/threonine protein phosphatase 1/2A (PP1/PP2A) to regulate CHT function, surface expression, and phosphorylation. In mouse cru...
متن کاملPhosphorylation of diacylglycerol kinase in vitro by protein kinase C.
We investigated the effects of enzyme phosphorylation in vitro on the properties of diacylglycerol kinase. Diacylglycerol kinase and protein kinase C, both present as Mr-80,000 proteins, were highly purified from pig thymus cytosol. Protein kinase C phosphorylated diacylglycerol kinase (up to 1 mol of 32P/mol of enzyme) much more actively than did cyclic AMP-dependent protein kinase. Phosphoryl...
متن کاملAGC protein kinase phosphorylation and protein kinase C.
Protein kinase cascades feature in many signal transduction pathways. For those discussed here, a single upstream protein kinase appears to be responsible for the control of multiple downstream targets. So how is specificity introduced into these events? For the downstream kinases (substrates) described here, it would appear that specificity is determined by substrate-directed events that are p...
متن کاملPhosphorylation of Staphylococcus aureus Protein-Tyrosine Kinase Affects the Function of Glucokinase and Biofilm Formation
Background: When Staphylococcus aureus is grown in the presence of high concentration of external glucose, this sugar is phosphorylated by glucokinase (glkA) to form glucose-6-phosphate. This product subsequently enters into anabolic phase, which favors biofilm formation. The presence of ROK (repressor protein, open reading frame, sugar kinase) motif, phosphate-1 and -2 sites, and tyrosine kina...
متن کاملRegulation of cellular protein phosphatase-1 (PP1) by phosphorylation of the CPI-17 family, C-kinase-activated PP1 inhibitors.
The regulatory circuit controlling cellular protein phosphatase-1 (PP1), an abundant group of Ser/Thr phosphatases, involves phosphorylation of PP1-specific inhibitor proteins. Malfunctions of these inhibitor proteins have been linked to a variety of diseases, including cardiovascular disease and cancer. Upon phosphorylation at Thr(38), the 17-kDa PP1 inhibitor protein, CPI-17, selectively inhi...
