Component of the outer dynein arm-docking complex (ODA-DC) that mediates outer dynein arms (ODA) binding onto the doublet microtubule. Involved in mediating assembly of both ODAs and their axonemal docking complex onto ciliary microtubules. Component of the outer dynein arm-docking complex along with ODAD2, ODAD3, ODAD4 and CLXN. Interacts with ODAD3. Interacts with ODAD4; this interaction may facilitate the recruitment and/or attachment of outer dynein arm docking complex proteins, including ODAD1, ODAD3, and ODAD4 to ciliary axonemes. Interacts with DNAH9. Interacts with MNS1 (PubMed:34715025). Interacts with PIERCE1 and PIERCE2; the interactions link the outer dynein arms docking complex (ODA-DC) to the internal microtubule inner proteins (MIP) in cilium axoneme (PubMed:34715025). Expressed in trachea multiciliated cells. Belongs to the ODA1/DCC2 family.
