Gene: CHRNA4 (cholinergic receptor nicotinic alpha 4 subunit) Homo sapiens
Symbol: CHRNA4
Name: cholinergic receptor nicotinic alpha 4 subunit
Description: Exhibits acetylcholine receptor activity and acetylcholine-gated cation-selective channel activity. Predicted to contribute to acetylcholine binding activity. Involved in several processes, including DNA repair; behavioral response to nicotine; and response to hypoxia. Localizes to acetylcholine-gated channel complex. Implicated in autosomal dominant nocturnal frontal lobe epilepsy 1 and nicotine dependence. Biomarker of Alzheimer's disease and Lewy body dementia.
Type: protein-coding
RefSeq Status: REVIEWED
