Protein Kinase C (19-36) is a synthetic peptide inhibitor widely used in biochemical research to study the mechanisms of signal transduction within cells. It acts as a pseudosubstrate that specifically inhibits Protein Kinase C (PKC) activity by binding to its catalytic site and competing with natural substrates. This makes it valuable for understanding PKC's role in cellular processes such as cell growth, differentiation, and apoptosis. Researchers also utilize it to explore the impact of PKC modulation in diseases such as cancer, cardiovascular disorders, and neurological conditions. Additionally, it aids in the development of therapeutic strategies by providing insights into PKC inhibition and its potential effects on disease progression.
