Summary: Enables acetylcholine-gated monoatomic cation-selective channel activity. Involved in presynaptic modulation of chemical synaptic transmission. Acts upstream of or within several processes, including learning or memory; nervous system development; and regulation of circadian sleep/wake cycle, sleep. Located in external side of plasma membrane. Part of acetylcholine-gated channel complex. Is active in cholinergic synapse; dopaminergic synapse; and synaptic membrane. Is expressed in several structures, including alimentary system; genitourinary system; integumental system; nervous system; and sensory organ. Used to study attention deficit hyperactivity disorder; autism spectrum disorder; and autosomal dominant nocturnal frontal lobe epilepsy 3. Human ortholog(s) of this gene implicated in autosomal dominant nocturnal frontal lobe epilepsy and autosomal dominant nocturnal frontal lobe epilepsy 3. Orthologous to human CHRNB2 (cholinergic receptor nicotinic beta 2 subunit). [provided by Alliance of Genome Resources, Nov 2024]

Data suggest that receptor complex assembly from Chrna4 and Chrnb2 on neuronal cell surface is up-regulated by nicotine; combined effects of increased assembly stoichiometry and preferential trafficking likely drive up-regulation of this receptor complex on neuronal cell surface upon nicotine exposure.

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.
