General annotation (Comments)

Function

Receptor for glutamate. The activity of this receptor is mediated by a G-protein that 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.
