Anti-UST antibodies are used in the immunodetection of the protein uronyl 2-sulfotransferase. In humans, the canonical protein has a reported length of 406 amino acid residues and a mass of 47.7 kDa. Its subcellular localization is in the Golgi. It is widely expressed across many tissue types. A member of the Sulfotransferase 3 protein family, ust is a reported sulfotransferase that catalyzes the transfer of sulfate to the position 2 of uronyl residues. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include 2OST and dermatan/chondroitin sulfate 2-sulfotransferase. UST gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some ust antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
