About CHRNA3

Cytogenetic location: 15q25.1 Genomic coordinates (GRCh38): 15:78,593,052-78,620,996 (from NCBI)

This gene has 8 transcripts (splice variants), 207 orthologues, 45 paralogues and is associated with 3 phenotypes. Biased expression in adrenal (RPKM 16.5), appendix (RPKM 2.4) and 2 other tissues.

Summary

This locus encodes a member of the nicotinic acetylcholine receptor family of proteins. Members of this family of proteins form pentameric complexes comprised of both alpha and beta subunits. This locus encodes an alpha-type subunit, as it contains characteristic adjacent cysteine residues. The encoded protein is a ligand-gated ion channel that likely plays a role in neurotransmission. Polymorphisms in this gene have been associated with an increased risk of smoking initiation and an increased susceptibility to lung Cancer. Alternatively spliced transcript variants have been described. [provided by RefSeq, Nov 2009]
