WebIn cell biology, Protein kinase C, commonly abbreviated to PKC (EC 2.7.11.13), is a family of protein kinase enzymes that are involved in controlling the function of other proteins through the phosphorylation of hydroxyl groups of serine and threonine amino acid residues on these proteins, or a member of this family. Phospholipase C performs a catalytic mechanism, depleting PIP2 and generating inositol trisphosphate (IP3) and diacylglycerol (DAG). Depletion of PIP2 inactivates numerous effector molecules in the plasma membrane, most notably PIP2 dependent channels and transporters responsible for setting the cell's membrane potential. great wall 60123
