CENP-E hangs on at dynamic microtubule ends.

During mitosis, kinetochores attach to microtubule plus ends, thus allowing dynamic microtubules to properly segregate chromosomes. How this type of 'end-on' attachment between microtubule plus ends and kinetochores is formed and maintained is unclear. CENP-E, a kinesin-7 family member, is now shown to have a role in associating kinetochores with dynamic microtubule plus ends.
