Minus-end microtubule-dependent motor protein involved in the regulation of cell division. Binds microtubules via its N-terminus containing the MyTH4 domain and binds F-actin via its FERM domain. Binding to calmodulin inhibits microtubule binding activity. Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Kinesin family. KIN-14 subfamily.
