变态Mad 2蛋白在检查点机制中充当分子开关,该检查点机制在细胞分裂期间监测染色体与纺锤体微管的适当附着。Mad 2在其检查点非活性形式和活性形式之间切换的非常缓慢的自发速率通过其两种形式之间的自我-自我相互作用被催化到生理相关的时间尺度上,最终导致大量的活性Mad 2。最近的结构,生物化学和细胞生物学的进展表明,Mad 2的催化转化需要一个主要的结构重排,通过一个部分未折叠的中间过渡。
The metamorphic Mad2 protein acts as a molecular switch in the checkpoint mechanism that monitors proper chromosome attachment to spindle microtubules during cell division. The remarkably slow spontaneous rate of Mad2 switching between its checkpoint inactive and active forms is catalyzed onto a physiologically relevant time scale by a self–self interaction between its two forms, culminating in a large pool of active Mad2. Recent structural, biochemical, and cell biological advances suggest that the catalyzed conversion of Mad2 requires a major structural rearrangement that transits through a partially unfolded intermediate.
