The microtubule-based mitotic spindle orchestrates chromosome segregation, facilitated by many microtubule-associated proteins. Kinesin-5 proteins are important components of the cell division machinery, and are involved in generation of mitotic spindle bipolarity by cross-linking microtubules. Kinesin-5s are members of the ATP- and MT-dependent kinesin superfamily of molecular motors. Human kinesin-5 is also a target for small molecule inhibitors that specifically bind to the motor domain and are currently in cancer clinical trials. The regulatory mechanisms that control kinesin-5 activity during mitosis and the effects of regulation on the kinesin-5-microtubule interaction remain unknown. Recent work has focused on a kinesin-5 specific region within the motor domain, loop5, as a potential regulatory switch. Kinesin-5-specific small molecule inhibitors bind beneath loop5, loop5 is rearranged when kinesin-5 binds to microtubules and residues adjacent to loop5 are subject to cell cycle-dependent tyrosine phosphorylation which could affect its conformation. It will be essential to consider these studies, which shed light on potential kinesin-5 regulatory mechanisms, as part of efforts to develop clinically effective kinesin-5 inhibitors.
