Used as a phosphorylation target in enzyme activity assays to study Protein Kinase C (PKC) function. Commonly employed in kinase assays to measure PKC activity in cell lysates or purified enzyme preparations. Helps in screening and evaluating PKC inhibitors or activators in drug discovery. Widely used in signal transduction research to understand cellular responses like proliferation, differentiation, and apoptosis. Compatible with radioactive (e.g., [γ-32P]ATP) or fluorescence-based detection methods. Supports high-throughput screening platforms in pharmaceutical and biochemical research.
