Kinesin family member that is involved in spindle formation and the movements of chromosomes during mitosis and meiosis. Binds to microtubules and to DNA (By similarity). Plays a role in congression of laterally attached chromosomes in NDC80-depleted cells (PubMed:25743205). Interacts with FAM83D (PubMed:18485706). Interacts with SIAH1 (PubMed:11146551). Expressed in bone, cartilage, joint capsule, ligament, skin, and primary cultured chondrocytes. Ubiquitinated; mediated by SIAH1 and leading to its subsequent proteasomal degradation. The disease is caused by variants affecting the gene represented in this entry. Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Kinesin family.
