Summaries for UGT1A4 Gene

Entrez Gene Summary for UGT1A4 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. This enzyme has some glucuronidase activity towards bilirubin, although is is more active on amines, steroids, and sapogenins. [provided by RefSeq, Jul 2008]

GeneCards Summary for UGT1A4 Gene

UGT1A4 (UDP Glucuronosyltransferase Family 1 Member A4) is a Protein Coding gene. Diseases associated with UGT1A4 include Crigler-Najjar Syndrome, Type I and Crigler-Najjar Syndrome, Type Ii. Among its related pathways are Drug metabolism - cytochrome P450 and Constitutive Androstane Receptor Pathway. Gene Ontology (GO) annotations related to this gene include protein homodimerization activity and enzyme binding. An important paralog of this gene is UGT1A5.

UniProtKB/Swiss-Prot for UGT1A4 Gene

  • UDPGT is of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds. This isoform glucuronidates bilirubin IX-alpha to form both the IX-alpha-C8 and IX-alpha-C12 monoconjugates and diconjugate. Isoform 2 lacks transferase activity but acts as a negative regulator of isoform 1 (By similarity).

    Molecular mass:

    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, UGT1A6, UGT1A7, UGT1A8, UGT1A9 and UGT1A10.
    • 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.

  • Crigler-Najjar syndrome 1 (CN1) [MIM:218800]: Patients have severe hyperbilirubinemia and usually die of kernicterus (bilirubin accumulation in the basal ganglia and brainstem nuclei) within the first year of life. CN1 inheritance is autosomal recessive. {ECO:0000269 PubMed:1634050}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Crigler-Najjar syndrome 2 (CN2) [MIM:606785]: Patients have less severe hyperbilirubinemia and usually survive into adulthood without neurologic damage. Phenobarbital, which induces the partially deficient glucuronyl transferase, can diminish the jaundice. CN2 inheritance is autosomal dominant. {ECO:0000269 PubMed:8276413, ECO:0000269 PubMed:8280139}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Gilbert syndrome (GILBS) [MIM:143500]: Occurs as a consequence of reduced bilirubin transferase activity and is often detected in young adults with vague non-specific complaints. {ECO:0000269 PubMed:17496722}. Note=The disease is caused by mutations affecting the gene represented in this entry.
