Selective Syntheses of Coumarin and Benzofuran Derivatives Using Phenols and α-Methoxy-β-ketoesters WebTreatment of undifferentiated P19 cells with concentrations of taxol greater than 4 x 10(-8) M caused microtubule bundling and multiple aster formation and promoted polymerization of the low levels of class III beta-tubulin found in these cells. In neurons, at 2 x 10(-8) M taxol, bundling of microtubules at the base of the neurite was apparent.

WebMay 14, 2024 · The binding of GTP to the E-site promotes tubulin polymerization and microtubule nucleation, so these rates exhibit a proportional dependence on the concentration of available GTP (Carlier et al., 1987). Polymerization and nucleation rate also strongly depend on the concentration of tubulin (Olmsted et al., 1974; Walker et al., 1988).
