- Description
- Predicted to enable acetylcholine receptor activity and acetylcholine-gated monoatomic cation-selective channel activity. Predicted to be involved in membrane depolarization; monoatomic ion transmembrane transport; and synaptic signaling. Predicted to act upstream of or within monoatomic ion transport. Predicted to be located in postsynaptic membrane. Predicted to be part of acetylcholine-gated channel complex. Predicted to be active in neuron projection; plasma membrane; and synapse. 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).
