Protein Structure
UniProt Annotation
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. {ECO:0000269PubMed:7617140, ECO:0000269PubMed:8738157, ECO:0000269PubMed:9473604}.
Subcellular Localization Cell membrane {ECO:0000269PubMed:7617140, ECO:0000269PubMed:8738157}; Multi-pass membrane protein {ECO:0000269PubMed:7617140, ECO:0000269PubMed:8738157}.
Disease Associations
Tissue Specificity Strongly expressed in the cerebellum. Expressed at low levels in hippocampus, hypothalamus and thalamus. No expression detected in liver. {ECO:0000269PubMed:7617140, ECO:0000269PubMed:8738157}.
