General annotation (Comments)

Function

G-protein coupled receptor for glutamate. Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors. Signaling inhibits adenylate cyclase activity.

Subunit structure

Interacts with PICK1. Ref.2

Subcellular location

Cell membrane; Multi-pass membrane protein.

Tissue specificity

Prominent expression in olfactory bulb, pontine gray, lateral reticular nucleus of the thalamus, and piriform cortex. Less abundant expression incerebral cortex, hippocampus, cerebellum, and mammillary body.

Sequence similarities

Belongs to the G-protein coupled receptor 3 family.
