title: Choreography of the 9-1-1 checkpoint complex: DDK puts a check on the checkpoints.
abstract: Checkpoint proteins respond to DNA damage by halting the cell cycle until the damage is repaired. In this issue of Molecular Cell, Furuya et al. (2010) provide evidence that checkpoint proteins need to be removed from sites of damage in order to properly repair it.
