Anti-TSR3 antibodies are used in the immunodetection of the protein TSR3 ribosome maturation factor. In humans, the canonical protein has a reported length of 312 amino acid residues and a mass of 33.6 kDa. Its subcellular localization is in the cytoplasm. A member of the TSR3 protein family, TSR3 is a reported aminocarboxypropyltransferase that catalyzes the aminocarboxypropyl transfer on pseudouridine at position 1248 (Psi1248) in 18S rRNA (Probable). Synonyms for this target antigen include 20S S rRNA accumulation protein 3 homolog, TSR3, 20S rRNA accumulation, homolog, TSR3, acp transferase ribosome maturation factor, and 18S rRNA aminocarboxypropyltransferase. TSR3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. These TSR3 antibodies are widely used in Western Blot experiments, among other applications.
