Kinesin-5 family proteins are essential for bipolar spindle assembly to ensure mitotic fidelity. Here we demonstrate evolutionary functional conservation of kinesin-5 between human and fission yeast. Human Eg5 expressed in the nucleus replaces fission yeast counterpart Cut7. Intriguingly, Eg5 overproduction results in cytotoxicity. This phenotype provides a useful platform for the development of novel kinesin-5 inhibitors as anti-cancer drugs.
