Entrez Gene Summary for GGT1 Gene

  • The enzyme encoded by this gene is a type I gamma-glutamyltransferase that catalyzes the transfer of the glutamyl moiety of glutathione to a variety of amino acids and dipeptide acceptors. The enzyme is composed of a heavy chain and a light chain, which are derived from a single precursor protein. It is expressed in tissues involved in absorption and secretion and may contribute to the etiology of diabetes and other metabolic disorders. Multiple alternatively spliced variants have been identified. There are a number of related genes present on chromosomes 20 and 22, and putative pseudogenes for this gene on chromosomes 2, 13, and 22. [provided by RefSeq, Jan 2014]

GeneCards Summary for GGT1 Gene

GGT1 (Gamma-Glutamyltransferase 1) is a Protein Coding gene. Diseases associated with GGT1 include Glutathionuria and Obstructive Jaundice. Among its related pathways are Eicosanoid Synthesis and Arachidonic acid 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 GGT2.

UniProtKB/Swiss-Prot Summary for GGT1 Gene

  • Cleaves the gamma-glutamyl bond of extracellular glutathione (gamma-Glu-Cys-Gly), glutathione conjugates, and other gamma-glutamyl compounds. The metabolism of glutathione releases free glutamate and the dipeptide cysteinyl-glycine, which is hydrolyzed to cysteine and glycine by dipeptidases. In the presence of high concentrations of dipeptides and some amino acids, can also catalyze a transpeptidation reaction, transferring the gamma-glutamyl moiety to an acceptor amino acid to form a new gamma-glutamyl compound. Initiates extracellular glutathione (GSH) breakdown, provides cells with a local cysteine supply and contributes to maintain intracellular GSH level. It is part of the cell antioxidant defense mechanism. Isoform 3 seems to be inactive.

  • N-glycosylated on both chains. Contains hexoses, hexosamines and sialic acid residues. Glycosylation profiles tested in kidney and liver tissues reveal the presence of tissue-specific and site-specific glycan composition, despite the overlap in composition among the N-glycans. A total of 36 glycan compositions, with 40 unique structures are observed. Up to 15 different glycans are observed at a single site, with site-specific variation in glycan composition. The difference in glycosylation profiles in the 2 tissues do not affect the enzyme activity.

GGT1_HUMAN
  • Glutathionuria (GLUTH) [MIM:231950]: A very rare, autosomal recessive metabolic disorder characterized by the presence of glutathione in the urine, due to generalized gamma-glutamyl transpeptidase deficiency. Most patients manifest mild to moderate mental retardation, and behavioral disturbance. Seizures, tremor, marfanoid features and strabismus are observed in some patients. {ECO:0000269 PubMed:29483667}. Note=The disease is caused by mutations affecting the gene represented in this entry. A large homozygous deletion that removes several exons of all isoforms of GGT1 has been found in one family affected by glutathionuria. {ECO:0000269 PubMed:29483667}.
