Predicted to enable glutathione peroxidase activity; glutathione transferase activity; and leukotriene-C4 synthase activity. Predicted to be involved in leukotriene biosynthetic process. Predicted to act upstream of or within leukotriene metabolic process. Predicted to be located in endoplasmic reticulum membrane. Predicted to be active in endoplasmic reticulum and nuclear envelope. Orthologous to human MGST2 (microsomal glutathione S-transferase 2).
