Acts 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. Is expressed in node. Used to study Kartagener syndrome; primary ciliary dyskinesia 23; and visceral heterotaxy. 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]
