Predicted to enable several functions, including glutathione binding activity; glutathione transferase activity; and leukotriene-C4 synthase activity. Predicted to be involved in glutathione metabolic process and long-chain fatty acid biosynthetic process. Predicted to act upstream of or within nitrobenzene metabolic process and xenobiotic catabolic process. Predicted to be located in cytosol and intercellular bridge. Orthologous to human GSTM4 (glutathione S-transferase mu 4). [provided by Alliance of Genome Resources, Apr 2022]
