- Description
- Predicted to contribute to acetylcholine binding activity and acetylcholine receptor activity. Predicted to be involved in several processes, including chemical synaptic transmission; regulation of membrane potential; and response to nicotine. Predicted to localize to acetylcholine-gated channel complex; neuron projection; and synapse. Human ortholog(s) of this gene implicated in autosomal dominant nocturnal frontal lobe epilepsy 4. Is expressed in interpeduncular nucleus medulla oblongata; interpeduncular nucleus tegmentum; neurons; and spinal cord. Orthologous to human CHRNA2 (cholinergic receptor nicotinic alpha 2 subunit).
