    Summary
    Enables acetylcholine-gated monoatomic cation-selective channel activity. Involved in monoatomic cation transport and skeletal muscle contraction. Part of acetylcholine-gated channel complex. Human ortholog(s) of this gene implicated in congenital myasthenic syndrome 1A and congenital myasthenic syndrome 1B. Orthologous to human CHRNA1 (cholinergic receptor nicotinic alpha 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.
