A G protein-coupled receptor required for olfactory imprinting a requisite in ordorant response such as benzaldehyde and isoamylalcohol. Expressed in interneurons AIY and AVB in L1 larvae. In adults, strong expression is seen in AIY and AIA but only weak expression in AVB. Worms exhibit olfactory imprinting to benzaldehyde and isoamylalcohol. Belongs to the nematode receptor-like protein sra family.
