Interphase APC/C–Cdc20 inhibition by cyclin A2–Cdk2 ensures efficient mitotic entry
Abstract
The Anaphase Promoting Complex/Cyclosome (APC/C) and its co-activator Cdc20 regulate mitotic progression, but both are also present in interphase. Here Hein and Nilsson show that Cyclin A2–CDK2 phosphorylates Cdc20 to inhibit APC/C–Cdc20 activity during this cell cycle phase to promote mitotic entry.
