Is predicted to encode a protein with the following domains: Serpentine type 7TM GPCR chemoreceptor Srx and 7TM GPCR, serpentine receptor class x (Srx). Is an ortholog of C. elegans srx-43. In C. elegans, srx-43 is involved in calcium-mediated signaling; cellular response to pheromone; and locomotory exploration behavior.
