CHRNA3 gene

cholinergic receptor nicotinic alpha 3 subunit

From NCBI Gene:

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]

From UniProt:

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.

From UniProt:

Bladder dysfunction, autonomic, with impaired pupillary reflex and secondary CAKUT (BAIPRCK): An autosomal recessive disease characterized by impaired innervation and autonomic dysfunction of the urinary bladder, hydronephrosis, vesicoureteral reflux, small kidneys, recurrent urinary tract infections, and progressive renal insufficiency. Additional autonomic features are impaired pupillary reflex and orthostatic hypotension. The disease manifests in utero or early childhood. [MIM:191800]
