Destroys radicals which are normally produced within the cells and which are toxic to biological systems. Homodimer; non-disulfide linked. Homodimerization may take place via the ditryptophan cross-link at Trp-33. The pathogenic variants ALS1 Arg-38, Arg-47, Arg-86 and Ala-94 interact with RNF19A, whereas wild-type protein does not. The pathogenic variants ALS1 Arg-86 and Ala-94 interact with MARCH5, whereas wild-type protein does not. Belongs to the Cu-Zn superoxide dismutase family. Note: This description may include information from UniProtKB.
