Latrunculin B is widely used in biological research as a potent inhibitor of actin polymerization. It disrupts the actin cytoskeleton in cells, making it a valuable tool for studying cell motility, shape, and intracellular transport mechanisms. In cancer research, it helps investigate the role of actin in tumor cell invasion and metastasis. Additionally, it is employed in developmental biology to understand processes like cell division and tissue organization. Its ability to selectively target actin filaments also aids in exploring the structural and functional dynamics of the cytoskeleton in various cellular contexts.
