Claim: SOD3 is a gene that encodes a member of the superoxide dismutase protein family and protects the brain, lungs, and other tissues from oxidative stress (a stress that is associated with increased production of oxidizing species or a significant decrease in the effectiveness of antioxidant defenses).
Evidence: This gene encodes a member of the superoxide dismutase (SOD) protein family. The product of this gene is thought to protect the brain, lungs, and other tissues from oxidative stress. Chemically, oxidative stress is associated with increased production of oxidizing species or a significant decrease in the effectiveness of antioxidant defenses, such as glutathione.
