Anti-RPUSD3 antibodies are used in the immunodetection of the protein RNA pseudouridine synthase D3. In humans, the canonical protein has a reported length of 351 amino acid residues and a mass of 38.5 kDa. Its subcellular localization is in the mitochondria. Up to 3 different isoforms have been reported for this protein. A member of the Pseudouridine synthase RluA protein family, RPUSD3 is known to catalyze uridine to pseudouridine isomerization (pseudouridylation) of specific mitochondrial mRNAs (mt-mRNAs), a post-transcriptional modification necessary for their translation. Synonyms for this target antigen include RNA pseudouridylate synthase domain containing 3, RNA pseudouridylate synthase domain-containing protein 3, and mitochondrial mRNA pseudouridine synthase RPUSD3. RPUSD3 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Western Blot is the most common application for the RPUSD3 antibodies listed below. Immunocytochemistry and Immunofluorescence are also common applications.
