CDC20 appears to act as a regulatory protein interacting with several other proteins at multiple points in the cell cycle. It is required for two microtubule-dependent processes, nuclear movement prior to anaphase and chromosome separation.CDC20 appears to act as a regulatory protein interacting with several other proteins at multiple points in the cell cycle.
