Progress through mitosis requires that the right protein be degraded at the right time. One ubiquitin ligase, the Anaphase Promoting Complex or Cyclosome (APC-C) targets most of the crucial mitotic regulators by changing its substrate specificity throughout mitosis. The Spindle Assembly Checkpoint (SAC) acts on the APC-C co-activator, Cdc20 to block the degradation of metaphase substrates, e.g.: Cyclin B1 and securin, but not others, e.g.: Cyclin A. How this is achieved is unclear. Here we show that Cdc20 binds to different sites on the APC-C depending on the SAC. Cdc20 requires APC3 and APC8 to bind and activate the APC-C when the SAC is satisfied, but only requires APC8 when the SAC is active. Moreover, APC10 is crucial for Cyclin B1 and securin but not Cyclin A destruction. We conclude that the SAC causes Cdc20 to bind to different sites on the APC-C and this alters APC-C substrate specificity.
