Other Information

**Key Characteristics** GPX4 is a dimeric enzyme composed of two identical subunits, each containing a selenocysteine (Sec) residue at position 46, which is critical for its catalytic activity. The enzyme is highly specific for reducing lipid hydroperoxides, including phospholipid hydroperoxides, and is also capable of reducing other oxidized compounds. GPX4 has a high Km for its substrates, indicating that it is a low-affinity enzyme, but its high Vmax values suggest that it can efficiently catalyze the reduction of lipid hydroperoxides under physiological conditions. The enzyme is also sensitive to changes in pH and temperature, which can affect its activity and stability. **Pathways and Functions** GPX4 is involved in several key pathways, including: 1. **Cellular oxidant detoxification**: GPX4 plays a crucial role in protecting cells from oxidative damage by reducing lipid hydroperoxides, which are produced during the metabolism of arachidonic acid and other polyunsaturated fatty acids. 2. **Lipid metabolism**: GPX4 is involved in the regulation of lipid metabolism, particularly in the context of the lipoxygenase pathway, which is responsible for the production of eicosanoids, including leukotrienes and resolvins. 3. **Inflammation regulation**: GPX4 has been implicated in the regulation of inflammation, particularly in the context of the resolution of inflammation, where it plays a role in the production of resolvins, which are specialized proresolving mediators (SPMs) that promote the resolution of inflammation. 4. **Spermatogenesis**: GPX4 has been shown to play a crucial role in spermatogenesis, where it is involved in the regulation of oxidative stress and the maintenance of sperm cell integrity. **Clinical Significance** GPX4 has been implicated in several clinical disorders, including: 1. **Atherosclerosis**: GPX4 has been shown to play a role in the regulation of lipid metabolism and the development of atherosclerosis, where it is involved in the production of oxidized lipids and the promotion of inflammation. 2. **Cancer**: GPX4 has been implicated in the regulation of oxidative stress and the development of cancer, where it is involved in the production of reactive oxygen species (ROS) and the promotion of tumorigenesis. 3. **Neurodegenerative diseases**: GPX4 has been shown to play a role in the regulation of oxidative stress and the development of neurodegenerative diseases, including Alzheimer's disease and Parkinson's disease, where it is involved in the production of ROS and the promotion of neuronal damage. 4. **Respiratory diseases**: GPX4 has been implicated in the regulation of oxidative stress and the development of respiratory diseases, including chronic obstructive pulmonary disease (COPD) and asthma, where it is involved in the production of ROS and the promotion of inflammation. In conclusion, GPX4 is a critical enzyme that plays a key role in the regulation of cellular antioxidant defenses, particularly in the context of oxidative stress and inflammation. Its dysregulation has been implicated in several clinical disorders, including atherosclerosis, cancer, neurodegenerative diseases, and respiratory diseases. Further research is needed to fully understand the role of GPX4 in human health and disease.

This is a preview of the gene's schema. Only a few entries are kept for 'singleCellExpressions,' 'mRNAExpressions,' and other large data arrays for visualization purposes. You can zoom in with the mouse wheel for a closer view, and the text will adjust automatically if necessary. For the full schema, download it here.
