The organization of intracellular components is dependent on the microtubule (MT) cytoskeleton, a network of rod-like filaments that form and disassemble on a rapid timescale. During cell division, MTs assemble into the mitotic spindle, where they generate forces that move chromosomes. MTs are also essential for cytokinesis, where they facilitate cleavage plane specification, constriction of the cleavage furrow, and abscission. The R. Ohi laboratory uses live cell imaging and reconstitution biochemistry to understand how MTs are organized and remodeled during cell division. Over the past...
