Anti-UTP25 antibodies are used in the immunodetection of the protein UTP25 small subunit processome component. In humans, the canonical protein has a reported length of 756 amino acid residues and a mass of 87.1 kDa. Its subcellular localization is in the nucleus. It is notably expressed in colon. A member of the UTP25 protein family, UTP25 is a known component of the ribosomal small subunit processome for the biogenesis of ribosomes, functions in pre-ribosomal RNA (pre-rRNA) processing (By similarity). Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include DEF, DIEXF, DJ434O14.5, U3 small nucleolar RNA-associated protein 25 homolog, UTP25 small subunit processor component, and C1orf107. UTP25 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
