Summary: Enables G protein-coupled acetylcholine receptor activity. Acts upstream of or within cardiac conduction system development and negative regulation of heart rate. Predicted to be located in postsynaptic membrane. Predicted to be active in dendrite; plasma membrane; and synapse. Is expressed in several structures, including cardiovascular system; central nervous system; digestive system; head; and neural tube. Human ortholog(s) of this gene implicated in several diseases, including Chagas disease; bipolar disorder; heroin dependence; major depressive disorder; and schizophrenia. Orthologous to human CHRM2 (cholinergic receptor muscarinic 2). [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.
