WebPLCs are a group of enzymes that produce a diacylglycerol (DAG) and a phosphorylated molecule, such as phosphorylcholine (P-choline) and phosphorylethanolamine (P-ethanolamine) ( 4 ). It is conceivable that PC-PLC activity is important in maintaining steady-state levels of PC, thus influencing cell membrane integrity and function. WebThese metabolites in turn control intracellular levels of free Ca 2+ and protein kinase C activity, respectively. This review, in addition to discussing molecular structure/ function …

WebAbstract. Phospholipase C (PLC) is an enzyme that hydrolyzes a glycerophospholipid at the phosphodiester bond between the glycerol backbone and the phosphate group. All known eukaryotic PLCs utilize only phosphoinositides (phosphatidylinositol and its phosphorylated derivatives) as substrates; hence, they are called phosphoinositide-specific ... WebNov 30, 1990 · Tyrosine phosphorylation in intact cells or in vitro increased the catalytic activity of PLC-γ1. Also, treatment of EGF-activated PLC-γ1 with a tyrosine-specific phosphatase substantially decreased the catalytic activity of PLC-γ1. These results suggest that the EGF-stimulated formation of inositol 1,4,5-trisphosphate and diacylglycerol in ...
