WebThe phospholipase C/PIP 2 system (sometimes termed the phosphoinositide second-messenger system) can therefore activate a variety of Ca 2 +-dependent mechanisms. One of these actually turns out to be protein kinase C, because this enzyme is activated by Ca 2 + as well as DAG. WebPhosphoinositide-specific phospholipase C (PI-PLC) cleaves, in a Ca (2+)-dependent manner, phosphatidylinositol-4,5-bisphosphate (PI-4,5-P2) into diacylglycerol (DAG) and inositol triphosphate (IP3). PI-PLCs are multidomain proteins that are structurally related to the PI-PLCζs, the simplest animal PI-PLCs. simpsons theme piano
