Deskripsi
In mitosis, Aurora B switches substrate specificity in response to phosphorylation of S227 in the activation loop by a cell cycle-processed active fragment of PKCε. Here, the authors show that this switch protects from chromosome non-disjunction by delaying anaphase entry and promoting TopoIIα-dependent resolution.
