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 By similarity.

Subcellular location

Cell membrane; Multi-pass membrane protein.

Tissue specificity

Expressed in many areas of the brain, especially in the cerebral cortex, hippocampus, and cerebellum. Expression of GRM7 isoforms in non-neuronal tissues appears to be restricted to isoform 3 and isoform 4. Ref.4

Sequence similarities

Belongs to the G-protein coupled receptor 3 family.
