title: Emi1 proteolysis: how SCF(beta-Trcp1) helps to activate the anaphase-promoting complex.
abstract: Emi1 inhibits the anaphase-promoting complex (APC) during S and G2 phase. Two papers by Guardavaccaro et al. and Margottin-Goguet et al. in the June issue of Developmental Cell now show that Emi1 degradation in early mitosis is mediated by beta-Trcp1, an adaptor protein that recruits proteins to the SCF ubiquitin ligase.
