SOD3 is secreted from cells into the extracellular region. Before secretion a portion of SOD3 molecules are cleaved near the C-terminus at glutamate-227 (glutamate-209 in the mature protein) (Olsen et al. 2004, Karlsson et al. 1993). Removal of the C-terminus prevents interaction with the extracellular matrix so cleaved molecules are soluble. Cleaved and uncleaved molecules are believed to be capable of forming mixed tetramers (Sandstrom et al. 1993).
