Anti-CFAP20 domain containing antibodies are used for the immunodetection of the protein encoded by the CFAP20DC gene. In humans, the canonical protein has a reported length of 689 amino acid residues and a mass of 76.3 kDa. Alternative splicing is reported to yield 2 different isoforms for this protein. Other names for this target antigen include protein CFAP20DC and uncharacterized protein C3orf67. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
