Summary: Enables acetylcholine-gated monoatomic cation-selective channel activity. Involved in several processes, including calcium ion import across plasma membrane; neuromuscular synaptic transmission; and positive regulation of locomotion involved in locomotory behavior. Located in neuron projection and postsynaptic membrane. Is expressed in body wall musculature; nervous system; and non-striated muscle. Human ortholog(s) of this gene implicated in several diseases, including alcohol dependence; alcohol use disorder; autosomal dominant nocturnal frontal lobe epilepsy (multiple); congenital myasthenic syndrome (multiple); and lung cancer (multiple). Orthologous to several human genes including CHRNA3 (cholinergic receptor nicotinic alpha 3 subunit) and CHRNA6 (cholinergic receptor nicotinic alpha 6 subunit).
