01

Overview

Manganese superoxide dismutase (MnSOD), or SOD2, is a mitochondrial antioxidant enzyme that catalyzes the dismutation of superoxide radicals into hydrogen peroxide and oxygen. It plays a crucial role in protecting cells from oxidative damage and maintaining redox balance. Dysregulation of MnSOD is implicated in various diseases, including cancer, neurodegeneration, and cardiovascular disorders. MnSOD expression and activity are regulated at multiple levels, including transcriptional control and post-translational modifications.
