Automated description from the Alliance of Genome Resources (Release 7.1.0)
Enables acetylcholine-gated monoatomic cation-selective channel activity. Involved in membrane depolarization and response to auditory stimulus. Acts upstream of or within several processes, including detection of mechanical stimulus involved in sensory perception of sound; excitatory postsynaptic potential; and inner ear morphogenesis. Predicted to be part of acetylcholine-gated channel complex. Predicted to be active in cholinergic synapse; neuron projection; and postsynaptic specialization membrane. Is expressed in brain. Human ortholog(s) of this gene implicated in lung small cell carcinoma. Orthologous to human CHRNA9 (cholinergic receptor nicotinic alpha 9 subunit).
