WebbPLC 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. WebbCalcium (Ca 2+) serves as a ubiquitous second messenger in all eukaryotes.For an ever-increasing number of biological processes, it has been found that temporally and spatially defined changes of Ca 2+ concentration in the cytoplasm or in defined organelles occur at one point or another.
