EMI1, a three-in-one ubiquitylation inhibitor

The anaphase-promoting complex/cyclosome (APC/C) is restricted by metazoan protein early mitotic inhibitor 1 (EMI1), a natural, potent inhibitor. New findings suggest that the multimodal inhibitory mechanisms of EMI1 control APC/C-dependent ubiquitylation.
