Gene Gene information from NCBI Gene database.
Entrez ID 1137
Gene name Cholinergic receptor nicotinic alpha 4 subunit
Gene symbol CHRNA4
Synonyms (NCBI Gene)
BFNCEBNEBN1NACHRNACHRA4NACRA4
Chromosome 20
Chromosome location 20q13.33
Summary This gene encodes a nicotinic acetylcholine receptor, which belongs to a superfamily of ligand-gated ion channels that play a role in fast signal transmission at synapses. These pentameric receptors can bind acetylcholine, which causes an extensive change
