Anti-DSH antibodies are protein reagents that detect specific antigens. The DSH antigen is another term for the human protein adenosine deaminase RNA specific, encoded by the ADAR gene. The protein is known to catalyze the hydrolytic deamination of adenosine to inosine in double-stranded RNA (dsRNA) referred to as A-to-I RNA editing. Canonically, it has an amino acid length of 1226 residues and a mass of 136.1 kilodaltons. Its subcellular localization is in the nucleus and cytoplasm and it is widely expressed in many tissue types.
