ua-62784

Inhibitor of microtubule polymerization in vitro. Interacts with tubulin dimers and promotes the accumulation of mammalian cells in apoptosis. Potentiates antiproliferative effects of vinblastine in H2B-GFP HeLa cells. Originally thought to inhibit CENP-E ATPase activity. Tcherniuk et al (2011) UA62784 is a cytotoxic inhibitor of microtubules, not CENP-E.
