Anti-HS3ST1 antibodies are used in the immunodetection of the protein heparan sulfate-glucosamine 3-sulfotransferase 1. In humans, the canonical protein has a reported length of 307 amino acid residues and a mass of 35.8 kDa. Its subcellular localization is in the Golgi. It is reported to be highly expressed in the brain and kidney and weakly expressed in the heart, lung and placenta. A member of the Sulfotransferase 1 protein family, HS3ST1 is a reported sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) to catalyze the transfer of a sulfo group to position 3 of glucosamine residues in heparan. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include 3OST1, heparan sulfate glucosamine 3-O-sulfotransferase 1, 3-OST-1, h3-OST-1, and 3OST. HS3ST1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is a widely used application for the HS3ST1 antibodies listed below. In addition, ELISA is also a common application.
