Nucleus and Mitotic Apparatus (NuMA) Protein in Cell Cycle Regulation

NuMA, the major protein of the "Nucleus and Mitotic Apparatus", is a structural protein in vertebrates involved in cell cycle regulation. It localizes to the nucleus during interphase, and accumulates at the spindle poles during mitosis and NuMA has been implicated in the formation of the mitotic spindle, in particular in focusing the spindle poles (1).
