phospholipase C, PLC is an enzyme that produces two second messengers IP3 and diacylglycerol (DAG) by cleavage of inositol phospolipids. IP3 in turn will trigger the release of calcium from intracellular stores, and DAG is going to activate protein kinase C (PKC)    .
There is some studies that shows that this enzyme has five groups, each group contains at least two isoforms.
- Eta is a superfamily of 1,2
- Beta 1,2,3 and 4 key step in the intracellular transduction of many extracellular signals, are regulated by heterotrimeric G protein-coupled receptors, Gq activates inositol phospholipid signalling pathway which in turn will activate PLC-beta enzyme.
- Delta 1,2,3
- Gamma 1,2 enzymes are controlled by receptor tyrosine kinases.
- Zeta 1
Most of them differ in their activation. Because, they are controlled by different receptors.
