Predicted to enable several functions, including anion binding activity; glutathione peroxidase activity; and glutathione transferase activity. Predicted to be involved in several processes, including cellular detoxification of nitrogen compound; long-chain fatty acid metabolic process; and regulation of release of sequestered calcium ion into cytosol. Predicted to be located in cytosol; intercellular bridge; and sarcoplasmic reticulum. Is expressed in several structures, including adrenal gland; alimentary system; central nervous system; genitourinary system; and sensory organ. Orthologous to human GSTM2 (glutathione S-transferase mu 2). [provided by Alliance of Genome Resources, Apr 2022]
