Component of the outer dynein arm-docking complex (ODA-DC) that mediates outer dynein arms (ODA) binding onto the doublet microtubule. Seems to regulate the assembly of both ODAs and their axonemal docking complex onto ciliary microtubules (By similarity). Regulates ciliary and flagellar motility and is required for cilia-driven determination of body laterality (PubMed:31240264). Component of the outer dynein arm-docking complex along with ODAD1, ODAD2, ODAD3 and ODAD4. Mice display typical phenotypes of primary ciliary dyskinesia, including hydrocephalus, situs inversus, and abnormal motility of trachea cilia and sperm flagella (PubMed:31240264). Strikingly, both males and females are viable and fertile (PubMed:31240264). The 9 + 2 axonemal structures of epithelial multicilia and sperm flagella are normal, but the formation of 9 + 0 nodal cilia is significantly disrupted (PubMed:31240264).
