    Summary
    Enables calcium channel regulator activity and voltage-gated calcium channel activity. Involved in chemical synaptic transmission and presynaptic modulation of chemical synaptic transmission. Acts upstream of or within several processes, including behavioral fear response; learning or memory; and transmission of nerve impulse. Located in presynaptic membrane. Is active in glutamatergic synapse. Is expressed in several structures, including alimentary system; brain; eye; reproductive system; and spinal cord. Used to study Werdnig-Hoffmann disease. Orthologous to human GRM7 (glutamate metabotropic receptor 7). [provided by Alliance of Genome Resources, Dec 2024]

    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.
