Anti-RNPC3 antibodies are used in the immunodetection of the protein RNA binding region (RNP1, RRM) containing 3. In humans, the canonical protein has a reported length of 517 amino acid residues and a mass of 58.6 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is reported to be highly expressed in the pancreas and kidney. RNPC3 is reported to participate in pre-mRNA U12-dependent splicing, performed by the minor spliceosome which removes U12-type introns. Synonyms for this target antigen include RNA-binding motif protein 40, RNA-binding protein 40, U11/U12 small nuclear ribonucleoprotein 65 kDa protein, U11/U12 snRNP 65 kDa protein, U11/U12 snRNP 65K, and RNA-binding region-containing protein 3. RNPC3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some RNPC3 antibodies may have been used in research and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
