Iron-sulfur (Fe-S) cluster binding motor protein that has a role in chromosome segregation during mitosis (By similarity). Required for mitotic chromosomal positioning and bipolar spindle stabilization. Binds 1 [4Fe-4S] cluster (By similarity). In the presence of oxygen, the [4Fe-4S] cluster may be converted to [2Fe-2S] (By similarity). Associated with mitotic chromosomes. Expressed in oocytes, eggs, testes and brain. Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Kinesin family. Chromokinesin subfamily.
