Controlling cytokinesis through promiscuous phosphorylation outside BARs.
In this issue of Molecular Cell, Roberts-Galbraith and colleagues report that a key cytokinetic regulator in fission yeast, Cdc15, is phosphorylated on numerous sites that collectively, but not individually, control its oligomerization state and its associations with the plasma membrane and interacting proteins.
