This gene is a member of the gamma-glutamyl transpeptidase gene family, and some reports indicate that it is capable of cleaving the gamma-glutamyl moiety of glutathione. The protein encoded by this gene is synthesized as a single, catalytically-inactive polypeptide, that is processed post-transcriptionally to form a heavy and light subunit, with the catalytic activity contained within the small subunit. The encoded enzyme is able to convert leukotriene C4 to leukotriene D4, but appears to have distinct substrate specificity compared to gamma-glutamyl transpeptidase. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Oct 2014]
GeneCards Summary for GGT5 Gene
GGT5 (Gamma-Glutamyltransferase 5) is a Protein Coding gene. Diseases associated with GGT5 include Capillariasis and Glutathionuria. Among its related pathways are Cytochrome P450 - arranged by substrate type and Glutathione metabolism. Gene Ontology (GO) annotations related to this gene include obsolete gamma-glutamyltransferase activity and glutathione hydrolase activity. An important paralog of this gene is GGT1.
UniProtKB/Swiss-Prot Summary for GGT5 Gene
Cleaves the gamma-glutamyl peptide bond of glutathione and glutathione-S-conjugate such as leukotriene C4 (PubMed:21447318). Does not cleaves gamma-glutamyl compounds such as gamma-glutamyl leucine (PubMed:21447318). May also catalyze a transpeptidation reaction in addition to the hydrolysis reaction, transferring the gamma-glutamyl moiety to an acceptor amino acid to form a new gamma-glutamyl compound (PubMed:21447318). Acts as a negative regulator of geranylgeranyl glutathione bioactivity by cleaving off its gamma-glutamyl group, playing a role in adaptive immune responses (PubMed:30842656).
