Summary: Enables protein homodimerization activity and superoxide dismutase activity. Involved in removal of superoxide radicals. Located in mitochondrion. Part of respiratory chain complex. Is expressed in several structures, including egg-laying apparatus; head; intestine; pharynx; and tail. Human ortholog(s) of this gene implicated in several diseases, including artery disease (multiple); autoimmune disease (multiple); cardiomyopathy (multiple); liver disease (multiple); and optic nerve disease (multiple). Orthologous to human SOD2 (superoxide dismutase 2). [provided by Alliance of Genome Resources, Jul 2025]

Data suggest that, under high glucose conditions, mitochondria-mediated oxidative stress and glycation are downstream targets of ins-7; this impairs neuronal system function and longevity via non-neuronal/neuronal crosstalk by affecting sod-3 and glod-4. (ins-7 = insulin related Probable insulin-like peptide beta-type 4; sod-3 = mitochondrial Mn+2 superoxide dismutase; glod-4 = glyoxalase 1)
