CC -!- FUNCTION: G-protein coupled receptor for glutamate. Ligand binding
CC causes a conformation change that triggers signaling via guanine
CC nucleotide-binding proteins (G proteins) and modulates the activity of
CC down-stream effectors. Signaling inhibits adenylate cyclase activity.
CC -!- SUBUNIT: Interacts with PICK1. {ECO:0000269|PubMed:11122333}.
CC -!- SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
CC -!- TISSUE SPECIFICITY: Prominent expression in olfactory bulb, pontine
CC gray, lateral reticular nucleus of the thalamus, and piriform cortex.
CC Less abundant expression incerebral cortex, hippocampus, cerebellum,
CC and mammillary body.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 3 family.
CC {ECO:0000305}.
