Metaphase PtK1 cells, lysed into polymerization-competent microtubule protein, maintain a spindle which will gain or lose birefringence depending on the concentration of disassembled tubulin subunits used in the lysis medium. Concentrations of tubulin subunits greater than the equilibrium monomer value promote a rate and extent of birefringence increase that is proportional to the subunit conce...
The microtubule-associated protein TOGp, which belongs to a widely distributed protein family from yeasts to humans, is highly expressed in human tumors and brain tissue. From purified components we have determined the effect of TOGp on thermally induced tubulin association in vitro in the presence of 1 mm GTP and 3.4 m glycerol. Physicochemical parameters describing the mechanism of tubulin po...
The fungicide carbendazim (CBZ) is known to disrupt microtubular structures in the testis and to cause testicular toxicity in rats. To investigate the mechanism underlying the toxicity of CBZ, tubulin and microtubule-associated proteins (MAPs) were isolated from rat testis and brain using two techniques. The effects of CBZ on MT assembly were compared with the known microtubule (MT) disruptors,...
