    Glossary Protein Kinase C

    enzymes that regulate various cellular functions by phosphorylating proteins

    Protein Kinase C (PKC) is a family of enzymes that play a crucial role in several cellular processes, including cell growth, differentiation, and apoptosis (programmed cell death). These enzymes are activated by signals such as increases in the concentration of calcium ions or diacylglycerol (DAG), and they function by phosphorylating various target proteins, thereby altering their activity. PKC is significant in many physiological and pathological processes, making it a key focus in research related to cancer, cardiovascular diseases, and neurological disorders.
