Summary: Enables acetylcholine binding activity and acetylcholine-gated monoatomic cation-selective channel activity. Acts upstream of or within regulation of membrane potential. Located in plasma membrane. Part of acetylcholine-gated channel complex. Is active in neuromuscular junction and postsynaptic specialization membrane. Is expressed in several structures, including forelimb bud; limb segment; lung; paraxial mesenchyme; and skeletal musculature. Human ortholog(s) of this gene implicated in congenital myasthenic syndrome 2A and congenital myasthenic syndrome 2C. Orthologous to human CHRNB1 (cholinergic receptor nicotinic beta 1 subunit).

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.
