title: Checkpoint signalling: Mad2 conformers and signal propagation.
abstract: The spindle checkpoint protein Mad2 has a tendency to form multimers and adopts at least two structural conformations. New work highlights the importance of the Mad2-Mad2 interaction, and suggests how spindle checkpoint signals are propagated away from kinetochores.
