Is predicted to encode a protein with the following domains: Glutathione S-transferase, N-terminal domain; Glutathione S-transferase, C-terminal domain; Glutathione S-transferase, C-terminal domain superfamily; Thioredoxin-like superfamily; Glutathione S-transferase, N-terminal; and Glutathione S-transferase, C-terminal. Is an ortholog of C. elegans gst-7 and gst-8. In C. elegans, gst-7 is involved in innate immune response.
