GPX4 (Glutathione Peroxidase 4) encodes a unique glutathione peroxidase that reduces lipid hydroperoxides to their corresponding alcohols, making it the central enzyme preventing ferroptosis - an iron-dependent, lipid peroxidation-driven form of cell death. Unlike other GPX family members, GPX4 directly reduces complex lipid peroxides within cellular membranes.
GPX4 catalyzes the reduction of lipid hydroperoxides using glutathione (GSH):
What distinguishes GPX4 from other glutathione peroxidases:
