Anti-heparan sulfate (glucosamine) 3-O-sulfotransferase 4 antibodies enable researchers to detect and measure the heparan sulfate (glucosamine) 3-O-sulfotransferase 4 antigen in biological samples. This target is a reported synonym of the HS3ST4 gene, which encodes heparan sulfate-glucosamine 3-sulfotransferase 4. This protein is known to function in metabolic processes, among other biological roles. The human version of heparan sulfate (glucosamine) 3-O-sulfotransferase 4 has a canonical amino acid length of 456 residues and a protein mass of 49.8 kilodaltons. It is reported to be localized in the Golgi of cells. Other names for this target antigen include 3-OST-4, 30ST4, and 3OST4.
