Summary
Predicted to enable acetylcholine binding activity and acetylcholine-gated monoatomic cation-selective channel activity. Predicted to contribute to acetylcholine receptor activity and heterocyclic compound binding activity. Involved in presynaptic modulation of chemical synaptic transmission. Is active in dopaminergic synapse. Is expressed in intestine; liver; nervous system; and retina. Human ortholog(s) of this gene implicated in several diseases, including alcohol dependence; bipolar disorder; cocaine dependence; depressive disorder; and nicotine dependence. Orthologous to human CHRNB3 (cholinergic receptor nicotinic beta 3 subunit). [provided by Alliance of Genome Resources, Jul 2025]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
