Anti-GAL3ST4 antibodies are used in the immunodetection of the protein galactose-3-O-sulfotransferase 4. In humans, the canonical protein has a reported length of 486 amino acid residues and a mass of 54.2 kDa. Its subcellular localization is in the Golgi. Up to 2 different isoforms have been reported for this protein. A member of the Galactose-3-O-sulfotransferase protein family, GAL3ST4 is known to catalyze the transfer of sulfate to beta-1,3-linked galactose residues in O-linked glycoproteins. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include beta-galactose-3-O-sulfotransferase 4 and gal-beta-1,3-GalNAc 3'-sulfotransferase. GAL3ST4 gene orthologs have been reported in the mouse, rat, bovine, zebrafish and chimpanzee species. Western Blot is the most common application for the GAL3ST4 antibodies listed below. ELISA and Immunofluorescence are also common applications.
