Predicted to be involved in regulation of cilium beat frequency. Predicted to act upstream of or within several processes, including cilium movement; outer dynein arm assembly; and ventricular system development. Predicted to be located in axoneme and ciliary base. Human ortholog(s) of this gene implicated in primary ciliary dyskinesia 23. Orthologous to human ODAD2 (outer dynein arm docking complex subunit 2). [provided by Alliance of Genome Resources, Apr 2022]
