Anti-SELENOO antibodies are used in the immunodetection of the protein selenoprotein O. In humans, the canonical protein has a reported length of 669 amino acid residues and a mass of 73.5 kDa. Its subcellular localization is in the mitochondria. It is notably expressed in many tissues, such as the pancreas and placenta. A member of the SELO protein family, SELENOO is known to catalyze the transfer of adenosine 5'-monophosphate (AMP) to Ser, Thr and Tyr residues of target proteins (AMPylation). Synonyms for this target antigen include protein adenylyltransferase SelO, mitochondrial. SELENOO gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some SELENOO antibodies may have been used in research and have associated citations. Immunocytochemistry is a widely used application for these antibodies. Western Blot, Immunofluorescence, and Immunohistochemistry are also common applications.
