In cyliated cells, dynein axonemal particle-specific protein required for deployment of ODA to the axoneme. Interacts with outer dynein arm (ODA) subunits. Interacts with DNAI2. Location is restricted to the outer dynein arm (ODA) sub-region of dynein axonemal particles (DynAPs). Expression is enriched in multiciliated cells in the epidermis and the nephrostomes of the pronephros. Mutant multiciliated cells show a severe loss of ODAs from motile cilia.
