Anti-UTP20 antibodies are used in the immunodetection of the protein UTP20 small subunit processome component. In humans, the canonical protein has a reported length of 2785 amino acid residues and a mass of 318.4 kDa. Its subcellular localization is in the nucleus. It is reported to be expressed in appendix, brain, colon, fetal liver, heart, ovary, pancreas, placenta, prostate, skeletal muscle, small intestine, spleen, testis and thymus. A member of the UTP20 protein family, UTP20 is known to be a part of the small subunit (SSU) processome, first precursor of the small eukaryotic ribosomal subunit. Synonyms for this target antigen include DRIM, small subunit processome component 20 homolog, NNP73, UTP20 small subunit (SSU) processome component, and 1A6/DRIM. UTP20 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. ELISA, Western Blot, Immunocytochemistry, and Immunofluorescence are common applications for UTP20 antibodies.
