Predicted to enable glutathione dehydrogenase (ascorbate) activity; glutathione transferase activity; and identical protein binding activity. Predicted to be involved in several processes, including L-ascorbic acid metabolic process; cellular response to arsenic-containing substance; and glutathione metabolic process. Predicted to be active in cytoplasm. Human ortholog(s) of this gene implicated in Alzheimer's disease; Parkinson's disease; and asthma. Orthologous to human GSTO2 (glutathione S-transferase omega 2).
