Title	Analysis of the midbody interactome reveals new roles for PP1 phosphatases in late cytokinesis
Description	The midbody is an organelle assembled at the intercellular bridge connecting the two daughter cells at the end of mitosis. It is essential for the final separation of the daughter cells and involved in other important processes, including cell fate, pluripotency, apical-basal polarity, and cilium/lumen formation. The midbody is composed of numerous proteins with diverse functions distributed in a precise pattern. Here we report the first characterization of the midbody protein-protein interaction network (interactome), which provides an extremely valuable resource for understanding its multiple roles. Analysis of this midbody interactome led to the discovery that PP1/MYPT1 phosphatase regulates microtubule dynamics in late cytokinesis through de-phosphorylation of the kinesin MKLP1/KIF23, a finding that unexpectedly expands the temporal window of activity of this phosphatase during mitosis.
