Anti-D-aminoacyl-tRNA deacylase 1 antibodies are used for the immunodetection of the protein encoded by the DTD1 gene. In humans, the canonical protein has a reported length of 209 amino acid residues and a mass of 23.4 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is reported to be expressed in many adult and fetal tissues. A member of the DTD protein family, it is known to be involved with DNA replication. Post-translational modifications have been described, including phosphorylation. Other names for this target antigen include D-tyrosyl-tRNA(Tyr) deacylase 1, DNA-unwinding element-binding protein B, gly-tRNA(Ala) deacylase, histidyl-tRNA synthase-related, histidyl-tRNA synthetase 2, and D-tyrosyl-tRNA deacylase 1 homolog. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
