Anti-TSR1 antibodies are used in the immunodetection of the protein TSR1 ribosome maturation factor. In humans, the canonical protein has a reported length of 804 amino acid residues and a mass of 91.8 kDa. Its subcellular localization is in the nucleus. It is notably expressed in many tissues, such as the appendix, tonsil, and adrenal gland. A member of the Bms1-like GTPase protein family, TSR1 is known to be required during maturation of the 40S ribosomal subunit in the nucleolus. Synonyms for this target antigen include pre-rRNA-processing protein TSR1 homolog. TSR1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some TSR1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
