Cytoplasmic dynein is involved in a wide variety of cellular functions. In addition to the initially characterized form (MAP 1C/dynein 1), a second form of cytoplasmic dynein (dynein 2) has been identified and implicated in intraflagellar transport (IFT) in lower eukaryotes and in Golgi organization in vertebrates. In the current study, the primary structure of the full-length dynein 2 heavy chain (HC) was determined from cDNA sequence. The dynein 1 and dynein 2 sequences were similar within the motor region, and around the light intermediate chain (LIC)-binding site within the N-terminal stem region. The dynein 2 HC co-immunoprecipitated with LIC3, a homologue of dynein 1 LICs. Dynein 2 mRNA was abundant in the ependymal layer of the neural tube and in the olfactory epithelium. Antibodies to dynein 2 HC, LIC3 and a component of IFT particles strongly stained the ependymal layer lining the lateral ventricles. Both dynein 2 HC and LIC3 staining was also observed associated with connecting cilia in the retina and within primary cilia of non-neuronal cultured cells. These data support a specific role for dynein 2 in the generation and maintenance of cilia.
