Predicted to be involved in cilium movement and radial spoke assembly. Predicted to act upstream of or within maintenance of ciliary planar beating movement pattern. Predicted to be located in cilium; nucleolus; and nucleoplasm. Predicted to be part of radial spoke head. Predicted to be active in axoneme. Human ortholog(s) of this gene implicated in primary ciliary dyskinesia 11. Orthologous to human RSPH4A (radial spoke head component 4A). [provided by Alliance of Genome Resources, Apr 2022]
