Gene: CHRNB1 (cholinergic receptor nicotinic beta 1 subunit) Homo sapiens
Symbol: CHRNB1
Name: cholinergic receptor nicotinic beta 1 subunit
Description: Exhibits transmitter-gated ion channel activity involved in regulation of postsynaptic membrane potential. Contributes to acetylcholine receptor activity. Involved in several processes, including behavioral response to nicotine; chemical synaptic transmission; and muscle fiber development. Localizes to acetylcholine-gated channel complex and neuromuscular junction. Implicated in congenital myasthenic syndrome 2A and congenital myasthenic syndrome 2C.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: acetylcholine receptor subunit beta; acetylcholine receptor, nicotinic, beta 1 (muscle); ACHRB; cholinergic receptor, nicotinic beta 1; cholinergic receptor, nicotinic, beta 1 (muscle); cholinergic receptor, nicotinic, beta polypeptide 1 (muscle); CHRNB; CMS1D; CMS2A; CMS2C; FLJ57107; SCCMS
