Anti-UDP glucuronosyltransferase family 1 member A6 antibodies are used in the immunodetection of the protein encoded by the UGT1A6 gene. In humans, the canonical protein has a reported length of 532 amino acid residues and a mass of 60.8 kDa. Its subcellular localization is in the ER. Alternative splicing is reported to yield 3 different isoforms for this protein. It is notably expressed in skin. A member of the UDP-glycosyltransferase protein family, it is known to be involved with metabolic processes. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include HLUGP, HLUGP1, UDPGT, UDPGT 1-6, UGT-1A, UGT-1C, UGT-1E, and GNT1.
