The target of the SAC is the essential APC/C activator Cdc20. It is unclear how the SAC inactivates Cdc20 but most current models suggest that Cdc20 forms a stable complex with the Mad2 checkpoint protein. Here we show that most Cdc20 is not in a complex with Mad2; instead Mad2 is required for Cdc20 to form a complex with another checkpoint protein, BubR1. We further show that during the SAC, the APC/C ubiquitylates Cdc20 to target it for degradation. Thus, ubiquitylation of human Cdc20 is not required to release it from the checkpoint complex, but to degrade it to maintain mitotic arrest.",
