Anti-ODAD2 antibodies are used in the immunodetection of the protein outer dynein arm docking complex subunit 2. In humans, the canonical protein has a reported length of 1044 amino acid residues and a mass of 115.7 kDa. Its subcellular localization is in the cytoplasm. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in respiratory epithelial cells. ODAD2 is a known component of the outer dynein arm-docking complex (ODA-DC) that mediates outer dynein arms (ODA) binding onto the doublet microtubule. The ODAD2 gene has been associated with the disease, Ciliary dyskinesia. Synonyms for this target antigen include CILD23, gudu, armadillo repeat containing 4, armadillo repeat-containing protein 4, testis tissue sperm-binding protein Li 74n, and ARMC4. ODAD2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
