Mitotic Spindle: Illuminating Spindle Positioning with a Biological Lightsaber.
Abstract:
In metazoans, positioning of the mitotic spindle is controlled by the microtubule-dependent motor protein dynein, which associates with the cell cortex. Using optogenetic tools, two new studies examine how the levels and activity of dynein are regulated at the cortex to ensure proper positioning of the mitotic spindle.
