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 (By similarity). May be required for motile cilia function (PubMed:24067530). Component of the outer dynein arm-docking complex along with ODAD1, ODAD2, ODAD4 and CLXN (By similarity). Interacts with ODAD1 (By similarity). 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). Enriched at centrioles in IMCD3 dividing cells. At 7.5 dpc specifically expressed in the ventral node. Mice have a spectrum of laterality defects, including complex congenital heart defects associated with heterotaxy, and airway epithelia show largely immotile cilia with loss of the outer dynein arms.
