Used primarily in biochemical and biomedical research to study cellular processes involving protein dephosphorylation. It acts as a potent inhibitor of protein phosphatases, especially PP1 and PP2A, making it a valuable tool for investigating signal transduction pathways, cell cycle regulation, and apoptosis. Its ability to induce hyperphosphorylation of proteins helps researchers understand the role of phosphorylation in diseases such as cancer and neurodegenerative disorders. Also used in marine toxin studies to assess shellfish contamination and develop detection methods for food safety monitoring.
