Anti-SHQ1 antibodies are used in the immunodetection of the protein SHQ1, H/ACA ribonucleoprotein assembly factor. In humans, the canonical protein has a reported length of 577 amino acid residues and a mass of 65.1 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. A member of the SHQ1 protein family, SHQ1 is known to be required for the quantitative accumulation of H/ACA ribonucleoproteins (RNPs), including telomerase, probably through the stabilization of DKC1, from the time of its synthesis until its association with NOP10, NHP2, and NAF1 at the nascent H/ACA RNA. Synonyms for this target antigen include GRIM-1, NEDDS, Shq1p, protein SHQ1 homolog, SHQ1 homolog, and DYT35. SHQ1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some SHQ1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, and Immunofluorescence are also common applications.
