WebTaxol binds to beta tubulin in a pocket on the luminal surface of the microtubule and counteracts the effects of GTP hydrolysis taking place on the other side of the beta tubulin molecule (Amos and Löwe, 1999; Prota et al., 2013). In so doing, the drug suppresses the disassembly of the polymer and thereby promotes its assembly. WebHeLa cells incubated with taxol for 20 h are blocked in late G 2 and/or M (ref. 2).
