The spindle checkpoint: structural insights into dynamic signalling
&
Abstract
Chromosome segregation is a complex and astonishingly accurate process whose inner working is beginning to be understood at the molecular level. The spindle checkpoint plays a key role in ensuring the fidelity of this process. It monitors the interactions between chromosomes and microtubules, and delays mitotic progression to allow extra time to correct defects. Here, we review and integrate findings on the dynamics of checkpoint proteins at kinetochores with structural information about signalling complexes.
