Glutathione Peroxidase 1 (GPX1), also known as Cellular Glutathione Peroxidase, is a 201 amino acid, 23 kDa member of the glutathione peroxidase antioxidant enzyme family. The Glutathione Peroxidase family protects cell surfaces, extracellular fluid components, and enzymes from oxidative stress by catalysing the reduction of hydrogen peroxide, lipid peroxides, and organic hydroperoxide using reduced glutathione.
