Acts upstream of or within several processes, including cerebrospinal fluid circulation; establishment of left/right asymmetry; and inner dynein arm assembly. Located in 9+2 motile cilium and cytosol. Is expressed in central nervous system; ileum; male reproductive gland or organ; oviduct; and respiratory system. Used to study Kartagener syndrome; hydrocephalus; primary ciliary dyskinesia 14; and visceral heterotaxy. Human ortholog(s) of this gene implicated in primary ciliary dyskinesia 14. Orthologous to human CCDC39 (coiled-coil domain containing 39). [provided by Alliance of Genome Resources, Apr 2022]
