Is predicted to encode a protein with the following domains: Glutathione S-transferase, C-terminal domain; Glutathione S-transferase, N-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-8;
gst-7; and
gst-5. In C. elegans,
gst-4 is involved in glutathione metabolic process.
