Other Information

**Key Characteristics** GGT1 exhibits the following key characteristics: 1. **Enzyme specificity**: GGT1 is a gamma-glutamyltransferase that catalyzes the transfer of gamma-glutamyl groups to amino acids, peptides, or other molecules. 2. **Substrate specificity**: GGT1 has a broad substrate specificity, including glutathione, amino acids, peptides, and other molecules. 3. **Catalytic activity**: GGT1 catalyzes the transfer of gamma-glutamyl groups to its substrates, facilitating the synthesis, conjugation, and recycling of glutathione. 4. **Expression pattern**: GGT1 is highly expressed in various tissues, including the retina, kidney, and brain. 5. **Regulatory mechanisms**: GGT1 is subject to various regulatory mechanisms, including post-translational modifications, protein-protein interactions, and transcriptional control. **Pathways and Functions** GGT1 is involved in several physiological and pathological pathways, including: 1. **Glutathione metabolism**: GGT1 plays a critical role in the synthesis, conjugation, and recycling of glutathione, a key antioxidant molecule. 2. **Inflammatory response**: GGT1 is involved in the regulation of inflammatory responses, including the production of leukotrienes and the activation of immune cells. 3. **Parasitic infections**: GGT1 has been implicated in the growth and survival of Leishmania parasites, a protozoan that causes leishmaniasis. 4. **Metabolic disorders**: GGT1 is involved in the regulation of metabolic disorders, including those related to biological oxidation enzymes and lipid metabolism. 5. **Antioxidant defense**: GGT1 contributes to the antioxidant defense system by facilitating the synthesis and recycling of glutathione. **Clinical Significance** GGT1 has significant clinical implications, including: 1. **Detoxification of aflatoxins**: GGT1 is involved in the detoxification of aflatoxins, a group of mycotoxins produced by Aspergillus species. 2. **Leishmaniasis**: GGT1 has been identified as a potential target for the treatment of leishmaniasis, a parasitic disease that affects millions of people worldwide. 3. **Metabolic disorders**: GGT1 is implicated in the pathogenesis of metabolic disorders, including those related to biological oxidation enzymes and lipid metabolism. 4. **Inflammatory diseases**: GGT1 contributes to the regulation of inflammatory responses, including those involved in diseases such as arthritis and asthma. 5. **Cancer**: GGT1 has been identified as a potential biomarker for cancer, including colorectal and breast cancers. In conclusion, GGT1 is an enzyme with a wide range of cellular and physiological functions, including the regulation of glutathione metabolism, inflammatory responses, and parasitic infections. Its clinical significance is underscored by its involvement in the detoxification of aflatoxins, leishmaniasis, metabolic disorders, and inflammatory diseases, making it a promising target for the development of novel therapeutic strategies.
