Anti-b3gat3 antibodies are used in the immunodetection of the protein beta-1,3-glucuronyltransferase 3. In humans, the canonical protein has a reported length of 335 amino acid residues and a mass of 37.1 kDa. Its subcellular localization is in the golgi. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the Glycosyltransferase 43 protein family, it is known to be involved with carbohydrate metabolism and homeostasis and protein glycosylation. Post-translational modifications have been described, including N-glycosylation. Synonyms for this target antigen include JDSCD, glcUAT-I, galactosylgalactosylxylosylprotein 3-beta-glucuronosyltransferase 3, Sqv-8-like protein, and GLCATI.
