This compound is widely utilized in biochemical research, particularly in the study of protein interactions and cellular processes. It acts as a potent inhibitor of calmodulin, a calcium-binding messenger protein, making it valuable for investigating calcium-mediated signaling pathways. Researchers often employ it to explore the role of calmodulin in various physiological functions, including muscle contraction, inflammation, and neurotransmitter release. Additionally, it is used in fluorescence microscopy and staining techniques due to its ability to bind specific cellular components, aiding in the visualization of cellular structures and dynamics. Its application extends to drug discovery, where it serves as a tool to screen and develop compounds targeting calmodulin-dependent mechanisms.
