Predicted to be involved in several processes, including cilium assembly; determination of left/right symmetry; and regulation of cilium beat frequency. Predicted to act upstream of or within determination of left/right symmetry. Predicted to be located in axoneme. Predicted to be active in cytoplasm and motile cilium. Human ortholog(s) of this gene implicated in primary ciliary dyskinesia 15. Orthologous to human CCDC40 (coiled-coil domain containing 40). [provided by Alliance of Genome Resources, Apr 2022]
