Summary: Enables G protein-coupled neurotransmitter receptor activity involved in regulation of postsynaptic membrane potential and G protein-coupled neurotransmitter receptor activity involved in regulation of presynaptic membrane potential. Acts upstream of or within regulation of G protein-coupled receptor signaling pathway. Part of receptor complex. Is active in GABA-ergic synapse; postsynaptic membrane; and presynaptic active zone membrane. Is expressed in several structures, including central nervous system; eye; genitourinary system; gut; and inner ear. Orthologous to human KCTD12 (potassium channel tetramerization domain containing 12). [provided by Alliance of Genome Resources, Jan 2025]

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.
