Spindle placement and spindle elongation are critical for proper cell division. manner. We demonstrate that during metaphase CDK1-mediated phosphorylation at T2055 negatively regulates NuMA cortical localization and that AR7 this phosphorylation is counteracted by PPP2CA phosphatase activity. We establish that this tug of war is essential for proper levels of cortical dynein and thus spindle… Continue reading Spindle placement and spindle elongation are critical for proper cell division.
