Calmodulin antagonist-1 (Cat No.: R020469) is a synthetic small-molecule inhibitor that selectively targets calmodulin (CaM), a calcium-binding messenger protein essential for regulating numerous enzymes and signaling pathways. By disrupting CaM-dependent interactions, it modulates processes such as cell cycle progression, apoptosis, neurotransmission, and smooth muscle contraction. This compound is widely employed in studies of Ca²⁺/CaM signaling, kinase regulation, and calcium-mediated cellular responses. Calmodulin antagonist-1 serves as a valuable research tool for exploring signal transduction, cancer biology, and therapeutic strategies targeting CaM pathways.
