Mob4 plays a role in spindle focusing in Drosophila S2 cells
... As reported previously (Goshima and Vale, 2003), S2 cells often show aberrant mitotic spindle phenotypes. Some S2 cells form monopolar spindles that subsequently can be converted to a bipolar spindle by a rescue process in which microtubules become organized to form a second, acentrosomal pole (~10% ...
