First, IP3 diffuses to the endoplasmic reticulum membrane where it binds to gated calcium ion channels. This causes calcium channels in the ER membrane to open and release large amounts of …
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. WebDiacylglycerol (which remains embedded in the membrane) and 1,4,5-triphosphate (which is released into the cytosol) initiate further signal transduction pathways through the activation of protein kinase C and intracellular Ca 2+ release (Fig. 5).
WebSUMMARY To explore the roles of vascular phospholipase C activity in the development of hyper-tension, phospholipase C activity was examined in the aortic wall of spontaneously hypertensive rats (SHR). Phospholipase C activity was significantly enhanced ( + 87%, p<0.005) in 14-week-old SHR as compared.with normotensive Wistar-Kyoto rats (WKY).
WebPhospholipase C performs a catalytic mechanism, depleting PIP2 and generating inositol trisphosphate (IP 3) and diacylglycerol (DAG).
