WebApr 27, 2010 · Receptor activation leads to phospholipase C (PLC) activation, which cleaves phosphatidylinositol 4,5-bisphosphate (PIP 2) into IP 3 and diacylglycerol (DAG). IP 3 then stimulates calcium release from the endoplasmic reticulum, and calcium controls the activity of numerous downstream targets. One of the downstream targets is protein … WebPIP2 is a cell membrane phospholipid which is cleaved by phospholipase C to form two intermediates: diacylglycerol (DAG) and inositol triphosphate (IP3) DAG (diacylglycerol) → PKC (protein kinase C) Protein kinase C (PKC) is activated by DAG, as well as by calcium ions released from sarcoplasmic reticulum under the influence of IP3

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).
