The centrosome contains proteins that control the organization of the microtubule cytoskeleton in interphase and mitosis. Its protein composition is tightly regulated through selective and cell cycle-dependent recruitment, retention, and removal of components. However, the mechanisms underlying protein delivery to the centrosome are not completely understood. We describe a novel function for the polarity protein Par6? in protein transport to the centrosome. We detected Par6? at the centrosome and centriolar satellites where it interacted with the centriolar satellite protein PCM-1 and the dynactin subunit p150(Glued). Depletion of Par6? caused the mislocalization of p150(Glued) and centrosomal components that are critical for microtubule anchoring at the centrosome. As a consequence, there were severe alterations in the organization of the microtubule cytoskeleton in the absence of Par6? and cell division was blocked. We propose a model in which Par6? controls centrosome organization through its association with the dynactin subunit p150(Glued).
