Predicted to enable several functions, including anion binding activity; dinitrosyl-iron complex binding activity; and glutathione peroxidase activity. Acts upstream of or within response to bacterium and response to stilbenoid. Predicted to be located in cytosol. Is expressed in several structures, including alimentary system; central nervous system; heart; skeleton; and urinary system. Human ortholog(s) of this gene implicated in asthma and ovarian cancer. Orthologous to several human genes including GSTA1 (glutathione S-transferase alpha 1); GSTA2 (glutathione S-transferase alpha 2); and GSTA3 (glutathione S-transferase alpha 3).
