BTB-1 inhibits Kif18A in an a

5、denosinetriphosphate (ATP)-competitive but microtubule-uncompetitive manner and slows down the progression ofcells through mitosis. 100 M BTB-1 does not significantly inhibit any of the other tested mitotic kinesins.BTB-1 competes with ATP for Kif18A binding only when the motor-protein is associated

6、 with itspseudosubstrate microtubules. HeLa cells treated with BTB-1 accumulate in mitosis in a dose-dependentmanner 1. BTB-1 shows cell toxicity with an EC50 values of 35.8 M. HeLa cells treated with 50 M BTB-1reveals severe defects in spindle morphology and chromosome alignment. Treatment with hig

The activity of His-Kif18Amotor at increasing concentrations of ATP ismonitored in the presence of 3 M Mts and increasing concentrations of BTB-1 (0.21 M, 0.42 M, 0.85 M,1.7 M) or DMSO
