Anti-CHCHD2 antibodies are used in the immunodetection of the protein coiled-coil-helix-coiled-coil-helix domain containing 2. In humans, the canonical protein has a reported length of 151 amino acid residues and a mass of 15.5 kDa. Its subcellular localization is in the nucleus and mitochondria. CHCHD2 is known to be a type of transcription factor. Synonyms for this target antigen include MIX17B, MNRR1, NS2TP, PARK22, coiled-coil-helix-coiled-coil-helix domain-containing protein 2, and C7orf17.
