Summary: Predicted to enable adenylate cyclase inhibiting G protein-coupled glutamate receptor activity; calcium-dependent protein binding activity; and calmodulin binding activity. Involved in presynaptic modulation of chemical synaptic transmission. Acts upstream of or within chemical synaptic transmission and learning. Located in neuron projection. Is active in cerebellar granule cell to Purkinje cell synapse; parallel fiber to Purkinje cell synapse; and presynaptic active zone membrane. Is expressed in central nervous system; dorsal root ganglion; foot; sensory organ; and skeleton. Orthologous to human GRM4 (glutamate metabotropic receptor 4).

This immuno-electron microscopic studies suggest that pre-synaptic metabotropic glutamate receptor 4 (mGluR4) in striatal glutamatergic terminals is expressed almost exclusively in cortical boutons to subserve regulatory influences upon a large contingent of corticostriatal terminals that preferentially target putative "indirect" pathway striatal projection neurons in mice.

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.

Status: VALIDATED

Description

Transcript Variant: This variant (2) lacks an exon in the 3' coding region and uses an alternate 3' terminal exon compared to variant 1. The resulting protein (isoform 2) is shorter and has a distinct C-terminus compared to isoform 1.
