Anti-UDP glucuronosyltransferase family 1 member A3 antibodies are used for the immunodetection of the protein encoded by the UGT1A3 gene. In humans, the canonical protein has a reported length of 534 amino acid residues and a mass of 60.3 kDa. Its subcellular localization is in the ER. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the UDP-glycosyltransferase protein family, it is reported to be a UDP-glucuronosyltransferase (UGT) that catalyzes phase II biotransformation reactions in which lipophilic substrates are conjugated with glucuronic acid to increase the metabolite's water solubility, thereby facilitating excretion into either the urine or bile. Other names for this target antigen include UDPGT 1-3, UGT-1C, UGT1-03, UGT1.3, UGT1A3S, UGT1C, UDP-glucuronosyltransferase 1A3, and UDPGT. A number of UDP glucuronosyltransferase family 1 member A3 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunofluorescence are also common applications.
