Closing the GAP: a role for a RhoA GAP in cytokinesis.
During cell division, cytokinesis partitions the cytoplasm to form two daughter cells. Recently in Developmental Cell, Minoshima et al. (2003) establish an important connection between three regulatory molecules that coordinate this process, showing that the mitotic kinase aurora B phosphorylates MgcRacGAP to convert it to a GAP for RhoA, a small GTPase that drives cytokinesis.
