Predicted to enable ATP hydrolysis activity; microtubule binding activity; and microtubule motor activity. Acts upstream of or within determination of left/right symmetry; negative regulation of smoothened signaling pathway; and photoreceptor cell outer segment organization. Located in cilium and cytoplasm. Part of Hedgehog signaling complex. Is expressed in head; myotome; neural tube; otic vesicle; and somite. Used to study idiopathic scoliosis. Human ortholog(s) of this gene implicated in acrocallosal syndrome; cleft lip; and hydrolethalus syndrome 2. Orthologous to human KIF7 (kinesin family member 7).
