Recombinant Human Neuronal acetylcholine receptor subunit alpha-3 (CHRNA3), Truncated

Uniprot Id

P32297

Target Species

Human

Target Name

CHRNA3

Target Full Name

Neuronal acetylcholine receptor subunit alpha-3

Target Function

After binding acetylcholine, the AChR responds by an extensive change in conformation that affects all subunits and leads to opening of an ion-conducting channel across the plasma membrane.

Target Subcellular Location

Cell junction, synapse, postsynaptic cell membrane; Multi-pass membrane protein. Cell membrane; Multi-pass membrane protein.

Target Protein Families

Ligand-gated ion channel (TC 1.A.9) family, Acetylcholine receptor (TC 1.A.9.1) subfamily, Alpha-3/CHRNA3 sub-subfamily

Target Background

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.
