Is predicted to encode a protein with the following domains: Frag1/DRAM/Sfk1; Short-chain dehydrogenase/reductase SDR; Frag1/DRAM/Sfk1 family; 7TM GPCR, serpentine receptor class r (Str); short chain dehydrogenase; Serpentine type 7TM GPCR chemoreceptor Str; and NAD(P)-binding domain superfamily. Is an ortholog of C. elegans dhs-22.
