Introduction of CHRNB1
The full name of CHRNB1 is acetylcholine receptor subunit beta. The chemical transmission of electrical signals from the nervous system to skeletal muscle is mediated by the muscle nicotinic acetylcholine receptor (nAChR) at the neuromuscular junction. nAChR consists of five homologous subunits. CHRNB1 is one of the subunits. The gene encoding the muscle receptor beta subunit, CHRNB1, is located on the short arm of chromosome 17. CHRNB1 and CHRND produce proteins with close homology to the α1 subunit, but without two adjacent cysteines in the N-terminal domain.

Function of CHRNB1 Membrane Protein
As one of the subunits of the nicotinic acetylcholine receptor, CHRNB1 is involved in the regulation of ion channel activity, thereby affecting the contractility of skeletal muscle. The expression levels in the nervous system, adrenal gland, thyroid gland and placenta are relatively high in healthy human. It has also been found to play a role in diseases such as myasthenia gravis, Alzheimer's disease, autism spectrum disorders and Down syndrome.

Application of CHRNB1 Membrane Protein in Literature
This study reported the presence of CHRNB1 at the cellular level in human skeletal muscle and placenta, and mRNA expression reflected protein expression in cell types.
This article reported that no CHRNB1 mutation was detected in 15 fatal multiple pterygium syndromes (MPS).
The β1 subunit exhibited significantly increased expression in lung tumors compared to non-tumor bronchial tissue.
This paper showed that CHRNB1 was associated with the susceptibility to nicotine dependence.
It has been reported that spontaneous mutation of the beta subunit in the acetylcholine receptor channel gate interrupted the leucine loop of the AChR channel gate resulting in an eight-fold increase in channel open time, and severe slow-channel congenital myasthenic syndromes (CMS) characterized by severe endplate myopathy and extensive remodeling of the postsynaptic membrane.
