Axonemal dynein complexes. (a) Axonemal ODA. The blue text denotes subunits found in ODA complexes in respiratory cilia, and red text denotes subunits found in ODA complexes in sperm flagella. (b) Axonemal inner arm I1/f complex subunits (IDA). (c) Monomeric IDAs. Each inner arm species is constructed around a distinct monomeric heavy chain associated with an actin monomer and either DNALI1 or centrin; species d contains two additional components. In most cases, the precise equivalence between the human and C. reinhardtii monomeric heavy chain species is uncertain.
