Predicted to enable glutathione transferase activity. Predicted to be involved in glutathione metabolic process and xenobiotic metabolic process. Predicted to act upstream of or within response to bacterium and response to stilbenoid. Predicted to be active in cytosol. Human ortholog(s) of this gene implicated in asthma and ovarian cancer. Orthologous to human GSTA1 (glutathione S-transferase alpha 1); GSTA2 (glutathione S-transferase alpha 2); and GSTA3 (glutathione S-transferase alpha 3).
