Dynein and kinesin

Illustration of the molecular motors involved with transport along the mitotic spindle.

The orange proteins are kinesins, molecular motors carrying proteins on their back. Striding from the kinetochore, on long molecular legs, are the dyneins, carrying the stop signal broadcasting system.
