Summaries for UGT1A8 Gene

Entrez Gene Summary for UGT1A8 Gene

  • This gene encodes a UDP-glucuronosyltransferase, an enzyme of the glucuronidation pathway that transforms small lipophilic molecules, such as steroids, bilirubin, hormones, and drugs, into water-soluble, excretable metabolites. This gene is part of a complex locus that encodes several UDP-glucuronosyltransferases. The locus includes thirteen unique alternate first exons followed by four common exons. Four of the alternate first exons are considered pseudogenes. Each of the remaining nine 5' exons may be spliced to the four common exons, resulting in nine proteins with different N-termini and identical C-termini. Each first exon encodes the substrate binding site, and is regulated by its own promoter. The enzyme encoded by this gene has glucuronidase activity with many substrates including coumarins, phenols, anthraquinones, flavones, and some opioids. [provided by RefSeq, Jul 2008]

GeneCards Summary for UGT1A8 Gene

UGT1A8 (UDP Glucuronosyltransferase 1 Family, Polypeptide A8) is a Protein Coding gene. Diseases associated with UGT1A8 include kernicterus. Among its related pathways are Metabolism and Metabolism. GO annotations related to this gene include protein homodimerization activity and enzyme binding. An important paralog of this gene is UGT2B15.

UniProtKB/Swiss-Prot for UGT1A8 Gene

  • UDPGT is of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. Isoform 2 lacks transferase activity but acts as a negative regulator of isoform 1.

    Size:
    530 amino acids
    Molecular mass:
    59742 Da
    Quaternary structure:
    • Isoform 1 interacts with isoform 2/i2 suggesting that oligomerization is involved in negative regulation of transferase activity by isoform 2. Isoform 1 also interacts with respective i2 isoforms of UGT1A1, UGT1A3, UGT1A4, UGT1A6, UGT1A7, UGT1A9 and UGT1A10.
    Miscellaneous:
    • The gene is part of the UGT1A complex locus which displays alternative use of promoters, first exons and terminal exons. The locus is defined by 13 first exons, which are alternatively spliced to 3 other common exons and 2 alternative terminal exons 5. From the 27 possible mRNA isoforms, 9 produce functionally active polypeptides (UGT1A1, 1A3, 1A4, 1A5, 1A6, 1A7, 1A8, 1A9 and 1A10) called isoforms 1 (i1). Use of an alternative exon 5 (5b) as terminal exon is leading to 9 additional alternatively spliced products termed isoforms i2 and which lack transferase activity
