Component of the outer dynein arm-docking complex (ODA-DC) that mediates outer dynein arms (ODA) binding onto the doublet microtubule (PubMed:25192045). Involved in mediating assembly of both ODAs and their axonemal docking complex onto ciliary microtubules (PubMed:25192045). Component of the outer dynein arm-docking complex along with ODAD1, ODAD2, ODAD4 and CLXN (PubMed:25192045). Interacts with ODAD1 (PubMed:25192045). 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 (By similarity). The disease is caused by variants affecting the gene represented in this entry.
