Second Messengers: Definition, Examples & Function
WebPLC uses hydrolysis of the membrane phospholipid PIP 2 to form IP 3 and diacylglycerol (DAG), two classic secondary messengers. DAG attaches to the plasma membrane and recruits protein kinase C (PKC). IP 3 diffuses to the ER and is bound to the IP3 receptor. The IP 3 receptor serves as a Ca 2+ channel, and releases Ca 2+ from the ER. WebApr 5, 2024 · The second pathway of DAG generation in plants includes the conversion of the membrane lipid phosphatidylcholine (PC) to DAG by the removal of the phosphocholine headgroup by phospholipase C (PLC) (Bates and Browse 2012; Bates et al. 2009).Alternatively, also a group of phosphoinositide-specific phospholipases C (PI … chip fontaine
