| description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 9.1.0) Predicted to enable acetylcholine binding activity and neurotransmitter receptor activity. Predicted to contribute to acetylcholine receptor activity and acetylcholine-gated monoatomic cation-selective channel activity. Involved in presynaptic modulation of chemical synaptic transmission. Acts upstream of or within response to nicotine. Part of acetylcholine-gated channel complex. Is active in cholinergic synapse and dopaminergic synapse. Is expressed in several structures, including brain; gut; lung; trigeminal nerve; and vagus ganglion. Human ortholog(s) of this gene implicated in chronic obstructive pulmonary disease; cocaine abuse; esophagus squamous cell carcinoma; nicotine dependence; and respiratory system cancer (multiple). Orthologous to human CHRNA5 (cholinergic receptor nicotinic alpha 5 subunit). PHENOTYPE: Mice homozygous for a knock-out allele are less sensitive to nicotine-induced seizures and exhibit a significantly shorter latency time to seizure. [provided by MGI curators] |
