Anti-SNRNP27 antibodies are used in the immunodetection of the protein small nuclear ribonucleoprotein U4/U6.U5 subunit 27. In humans, the canonical protein has a reported length of 155 amino acid residues and a mass of 18.9 kDa. Its subcellular localization is in the nucleus. It is notably widely expressed in many tissue types. A member of the SNUT3 protein family, SNRNP27 is believed to play a role in mRNA splicing. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include RY1, U4/U6.U5 small nuclear ribonucleoprotein 27 kDa protein, U4/U6.U5 tri-snRNP-associated 27 kDa protein, U4/U6.U5 tri-snRNP-associated protein 3, and 27K. SNRNP27 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is the most common application for the SNRNP27 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
