However, this system can be tailored in vitro (in a lab) to generate completely different motion. As seen in this video, instead of the kinesin protein “walking” along the microtubules, the “motors” ...

a non-motor microtubule-associated protein (MAP)) and a kinesin-4 motor — comprise a minimal module that can dynamically organize antiparallel microtubules into a midzone of defined size.
