Yap and colleagues identify an extramitotic role for the centralspindlin complex, a Rho signalling regulator during cytokinesis. They show that centralspindlin interacts with α-catenin, and promotes epithelial junctional integrity by recruiting the ECT2 RhoGEF to the zonula adherens, as well as by inhibiting the junctional localization of the p190 B RhoGAP.
