Summary: Enables group III metabotropic glutamate receptor activity. Predicted to be involved in several processes, including adenylate cyclase-inhibiting G protein-coupled glutamate receptor signaling pathway; detection of mechanical stimulus involved in sensory perception of pain; and modulation of chemical synaptic transmission. Predicted to act upstream of or within signal transduction. Predicted to be located in neuron projection; neuronal cell body; and presynaptic membrane. Predicted to be integral component of plasma membrane. Is expressed in several structures, including eye; gonad; ileum; liver and biliary system; and nervous system. Human ortholog(s) of this gene implicated in attention deficit hyperactivity disorder; autistic disorder; and schizophrenia. Orthologous to human GRM8 (glutamate metabotropic receptor 8).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
