Glutathion peroxydase 4
The antioxidant enzyme glutathione peroxidase 4 (GPX4) belongs to the family of glutathione peroxidases, which consists of 8 known mammalian isoenzymes (GPX1–8). GPX4 catalyzes the reduction of hydrogen peroxide, organic hydroperoxides, and lipid peroxides at the expense of reduced glutathione and functions in … See more Glutathione peroxidase 4, also known as GPX4, is an enzyme that in humans is encoded by the GPX4 gene. GPX4 is a phospholipid hydroperoxidase that protects cells against membrane lipid peroxidation. See more Mammalian GPX1, GPX2, GPX3, and GPX4 (this protein) have been shown to be selenium-containing enzymes, whereas GPX6 is a selenoprotein in humans with cysteine-containing … See more In mouse and rat, three distinct GPX4 isoforms with different subcellular localization are produced through alternative splicing and transcription initiation; cytosolic GPX4, mitochondrial GPX4 (mGPX4), and nuclear GPX4 (nGPX4).
