Enables acetylcholine-gated cation-selective channel activity. Acts upstream of or within cholinergic synaptic transmission; detection of mechanical stimulus involved in sensory perception of sound; and inner ear morphogenesis. Predicted to be located in axon and perikaryon. Predicted to be active in neuron projection and synapse. Predicted to be integral component of plasma membrane. Orthologous to human CHRNA10 (cholinergic receptor nicotinic alpha 10 subunit). [provided by Alliance of Genome Resources, Apr 2022]
