Microtubules, the polymers that compose the mitotic spindle, and microtubule-based motor proteins have vital roles in mitosis. Several members of the kinesin motor superfamily have been implicated in spindle formation, chromosome movement, and cytokinesis.icrotubules, the polymers that compose the mitotic spindle, and microtubule-based motor proteins have vital roles in mitosis.

One of the first proteins known to be phosphorylated by ERK was a microtubule-associated protein (MAP). As discussed below, many additional targets for phosphorylation by MAPK were later found, and the protein was renamed mitogen-activated protein kinase (MAPK). The series of kinases from RAF to MEK to MAPK is an example of a protein kinase cascade.
