Bind to microtubules in an ATP-insensitive manner (in vitro) (PubMed:8075402, PubMed:17244481). Homodimer and heterodimer with KIN14M/KATB (in vitro) (PubMed:17244481). Composed of three structural domains; a small globular N-terminal, a central alpha-helical coiled coil and a large globular C-terminal which is responsible for the motor activity (it hydrolyzes ATP and binds microtubules). Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Kinesin family. KIN-14 subfamily.
