Summary: Enables acetylcholine-gated monoatomic cation-selective channel activity. Involved in presynaptic modulation of chemical synaptic transmission. Acts upstream of or within membrane depolarization and regulation of dopamine secretion. Part of acetylcholine-gated channel complex. Is active in dopaminergic synapse; postsynaptic membrane; and presynaptic membrane. Is expressed in central nervous system and retina. Human ortholog(s) of this gene implicated in alcohol use disorder; cocaine abuse; and nicotine dependence. Orthologous to human CHRNA6 (cholinergic receptor nicotinic alpha 6 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.
