Human UDP-glucuronosyltransferase 2B7.

Area of Science:

• Biochemistry
• Pharmacology
• Molecular Biology

Background:

• UDP-Glucuronosyltransferases (UGTs) are key enzymes in drug metabolism, facilitating detoxification by converting lipophilic compounds into hydrophilic derivatives for excretion.
• While primarily involved in detoxification, glucuronidation can also produce biologically active or toxic metabolites.
• UGTs are implicated in regulating nuclear receptor ligand concentrations, influencing cellular signaling pathways.

Purpose of the Study:

• To review the identification, expression, and localization of the UGT2B7 isoform in human tissues.
• To explore the substrate specificity and gene promoter characteristics of UGT2B7.
• To consolidate current knowledge on UGT2B7's role in drug metabolism and its extrahepatic and nuclear localization.

Main Methods:

• Literature review of published studies and investigator data on UGT2B7.
• Analysis of existing information regarding UGT2B7 expression patterns in various human tissues.
• Examination of data on UGT2B7 substrate specificity, localization (including nuclear and extrahepatic), and gene structure.

Main Results:

• UGT2B7 is a significant human UGT2B subfamily isoform involved in metabolizing diverse endogenous compounds and xenobiotics.
• The review covers the history of UGT2B7 identification and its expression across human tissues.
• Information on UGT2B7's substrate range, extrahepatic and nuclear localization, and gene/promoter characteristics is compiled.

Conclusions:

• UGT2B7 plays a crucial role in the glucuronidation of numerous substrates, impacting drug metabolism and detoxification.
• Understanding UGT2B7's specific functions, localization, and genetic regulation is vital for predicting drug efficacy and toxicity.
• This review provides a comprehensive overview of UGT2B7, highlighting its importance in human health and disease.
