How APC/C orders destruction

Bettina A. Buschhorn & Jan-Michael Peters

The APC/C coordinates cell-cycle progression through mitosis, meiosis and the G1 phase of the cell cycle. In association with its co-activator proteins — Cdc20 or Cdh1 — APC/C polyubiquitinates regulatory proteins such as securin, cyclin A and geminin, whose subsequent destruction by the 26S proteasome is important for cell-cycle progression (reviewed in ref.
