Mitosis: riding the protofilament curl.
More than 50 years ago, microtubule depolymerization was proposed as the force responsible for chromosome movement. New studies measure the force produced by depolymerization and show that protein ring complexes can couple depolymerization to movement. These results have implications for anaphase chromosome motility and mitotic evolution.
