Summary
Predicted to enable G protein-coupled acetylcholine receptor activity. Involved in postsynaptic modulation of chemical synaptic transmission and regulation of postsynaptic membrane potential. Acts upstream of or within regulation of locomotion. Is active in Schaffer collateral - CA1 synapse; cholinergic synapse; and postsynaptic membrane. Is expressed in central nervous system; exocrine system; retina; and urinary system. Human ortholog(s) of this gene implicated in Lambert-Eaton myasthenic syndrome; asthma; and myasthenia gravis. Orthologous to human CHRM1 (cholinergic receptor muscarinic 1). [provided by Alliance of Genome Resources, Oct 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.
