Involved in cilium movement; outer dynein arm assembly; and regulation of cilium assembly. Acts upstream of or within several processes, including determination of heart left/right asymmetry; epithelial cilium movement involved in extracellular fluid movement; and flagellated sperm motility. Located in centriole and ciliary basal body. Is expressed in node and trachea. Used to study Kartagener syndrome and primary ciliary dyskinesia 30. Human ortholog(s) of this gene implicated in primary ciliary dyskinesia 30. Orthologous to human ODAD3 (outer dynein arm docking complex subunit 3).
