Anti-ADAT3 antibodies are used in the immunodetection of the protein adenosine deaminase tRNA specific 3. In humans, the canonical protein has a reported length of 351 amino acid residues and a mass of 38.1 kDa. The ADAT3 protein is a member of the Cytidine and deoxycytidylate deaminase protein family. Synonyms for this target antigen include adenosine deaminase, tRNA-specific 3, TAD3 homolog, tRNA-specific adenosine-34 deaminase subunit ADAT3, and probable inactive tRNA-specific adenosine deaminase-like protein 3.
