Chrnb2 - cholinergic receptor nicotinic beta 2 subunit

Enables acetylcholine binding activity; acetylcholine-gated cation-selective channel activity; and quaternary ammonium group binding activity. Contributes to heterocyclic compound binding activity. Involved in acetylcholine receptor signaling pathway; cholinergic synaptic transmission; and response to nicotine. Located in plasma membrane raft. Part of acetylcholine-gated channel complex. Is active in cholinergic synapse. Is integral component of postsynaptic specialization membrane and integral component of presynaptic membrane. 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, Apr 2022]
