WebThe phospholipase cleaves PIP 2 , creating DAG and IP 3 . The DAG is sent towards other pathways as a second messenger. The IP 3 is diffused into the ER and binds to the IP 3 gated calcium channel, which allows the gates to open; and out goes Ca 2+ . The Ca 2+ ions flow out of the ER, acting as a second messenger. WebSecreted NO enters platelets where it activates the enzyme guanylate cyclase, which then stimulates the formation of cGMP (cyclic guanosine mono-phosphate). cGMP then blocks the function of phospholipase C. In the absence of NO, phospholipase C cleaves the membrane phospholipid PIP2, which leads to the production of inositol triphosphate (IP3).

WebPhosphatidylinositol 4,5-bisphosphate or PIP2 is an important second messenger for a number of signaling processes. When certain extracellular signals are received, Phosphilipase C cleaves phosphatidylinositol into DAG and PIP2. PIP2 has been shown to interact with actin structural proteins including profiling, gelsolin, and cofilin, and ...
