Anti-NPM3 antibodies are used in the immunodetection of the protein nucleophosmin/nucleoplasmin 3. In humans, the canonical protein has a reported length of 178 amino acid residues and a mass of 19.3 kDa. Its subcellular localization is in the nucleus. It is ubiquitously expressed across many tissue types. A member of the Nucleoplasmin protein family, NPM3 is reported to play a role in the regulation of diverse cellular processes such as ribosome biogenesis, chromatin remodeling or protein chaperoning. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include TMEM123, nucleoplasmin-3, nucleophosmin/nucleoplasmin family, member 3, and PORMIN. NPM3 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some NPM3 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
