abstract

  • gamma-Glutamyl transpeptidase is a key enzyme in glutathione (GSH) salvage, metabolism of endogenous mediators such as leukotrienes and prostaglandins, detoxification of xenobiotics including environmentally important compounds and carcinogens, and cellular processes dependent on the oxidation/reduction of glutathione. The enzyme is widely distributed, and these functions often occur in separate tissues and in response to different stimuli. Evidence indicates that gamma-glutamyl transpeptidase plays a direct role in some hepatic and renal responses to injury. In the mouse gamma-glutamyl transpeptidase is a single copy gene expressed from at least seven promoters, and many of the transcribed gamma-glutamyl transpeptidase RNAs are restricted in their expression. Studies that combine analyses of cellular processes with a knowledge of gene structure and expression hold promise for unravelling how these two different levels of function are integrated.
