Response of microtubules to the addition of colchicine and tubulin–colchicine: evaluation of models for the interaction of drugs with microtubules
1 Apr 1997
Abstract excerpt
The effects of free drug and tubulin-drug complexes on steady-state GTP/GDP-associated microtubules and on equilibrium guanosine 5'[beta,gamma-imido]triphosphate-associated microtubules are compared. The addition of colchicine or the tubulin-colchicine complex (TuCol) to steady-state microtubules induces microtubule disassembly. Only limited disassembly of equilibrium microtubules is observed under similar...
