描述 | Kif18A is a mitotic motor protein essential for the correct alignment of chromosomes at the spindle equator. BTB1 potently inhibits the ATPase activity of Kif18A with an IC50 value of 1.69μM. The re-synthesized BTB1 inhibited His-Kif18Amotor with equal potency (IC50=1.86μM). The flushing in of 100μM BTB1 almost completely inhibited His-Kif18AFL-dependent microtubule motility. After the wash-out of BTB1, His-Kif18AFL regained most of its activity. The ATPase activity of His-Kif18Amotor was not affected by BTB1(100μM) in the absence of microtubules. BTB1 significantly inhibited microtubule-stimulated ATPase activity of His-Kif18Amotor as compared to the DMSO-treated group. Incubation of HeLa cells with BTB1 (30 and 40μM) for 18h induced the accumulation of cells in mitosis[3]. |
作用机制 | BTB1 is a potent and selective Kif18A inhibitor that reversibly inhibits the motility of Kif18A in an ATP-competitive manner[3]. |
