Multiple activities cooperate to determine the architecture of the mitotic spindle. Kip3 is a kinesin-8 motor protein in budding yeast that acts as a microtubule depolymerase. Now Kip3 is shown to also crosslink and slide antiparallel microtubules, providing additional insights into how kinesin-8 motors control spindle integrity.
