Anti-SNRPD1 antibodies are used in the immunodetection of the protein small nuclear ribonucleoprotein D1 polypeptide. In humans, the canonical protein has a reported length of 119 amino acid residues and a mass of 13.3 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is notably widely expressed in many tissue types. A member of the SnRNP core protein family, SNRPD1 is reported to play a role in pre-mRNA splicing as a core component of the spliceosomal U1, U2, U4 and U5 small nuclear ribonucleoproteins (snRNPs), the building blocks of the spliceosome. Synonyms for this target antigen include SMD1, SNRPD, Sm-D1, small nuclear ribonucleoprotein Sm D1, Sm-D autoantigen, and HsT2456. SNRPD1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of SNRPD1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
