The spindle checkpoint

Curr Opin Genet Dev. 1999 Feb;9(1):69-75. doi: 10.1016/s0959-437x(99)80010-0.

Abstract

Prior to sister-chromatid separation, the spindle checkpoint inhibits cell-cycle progression in response to a signal generated by mitotic spindle damage or by chromosomes that have not attached to microtubules. Recent work has shown that the spindle checkpoint inhibits cell-cycle progression by direct binding of components of the spindle checkpoint pathway to components of a specialized ubiquitin-conjugating system that is responsible for triggering sister-chromatid separation.
