The minus end-directed microtubule motor dynein/dynactin has been implicated in the silencing of the mitotic checkpoint by "stripping" checkpoint proteins off kinetochores.
The fighters captured the checkpoints, made off with weapons and ammunition, but failed to leave anyone to guard the positions.
NATO troops later closed roads leading to the checkpoints, cutting off the only link between northern Kosovo and Serbia.
The government's main strategy in dealing with rebel-held areas in Damascus has been to surround them with checkpoints, cut off water and electricity and bombard them.

The military official said the vehicle had approached the checkpoint, turned off its lights, then continued driving, nearly hitting the soldiers.
When we extended our NDGA assay to test for the transport of other mitotic checkpoint proteins off kinetochores, we found that hMad1, hMps1, hSpindly, hCdc27 and cyclin-B were also transported by dynein/dynactin to the spindle poles (Figure 6B, S4).
