Probable olfactory receptor. Highly expressed in the olfactory rosette (PubMed:17717047). Specifically localizes to crypt neurons in the olfactory neuroepithelium (PubMed:22038944). Colocalizes with the inhibitory G-protein gnaia in crypt neurons (PubMed:22038944). Not detected in other tissues tested (PubMed:17717047). Belongs to the G-protein coupled receptor 1 family.
