Anti-selenophosphate synthetase 2 antibodies are used for the immunodetection of the protein encoded by the SEPHS2 gene. In humans, the canonical protein has a reported length of 448 amino acid residues and a mass of 47.3 kDa. A member of the Selenophosphate synthase 1 protein family, it is known to be involved with protein phosphorylation. Post-translational modifications have been described, including ubiquitination. Other names for this target antigen include selenide, water dikinase 2, selenium donor protein 2, selenophosphate synthase 2, selenoprotein SEPHS2, and SPS2. Gene orthologs have been identified in the mouse, rat, bovine and chimpanzee species. Some selenophosphate synthetase 2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
