Summary: Enables acetylcholine-gated cation-selective channel activity. Acts upstream of or within cation transport; detection of mechanical stimulus involved in sensory perception of sound; and inner ear morphogenesis. Predicted to be part of acetylcholine-gated channel complex. Predicted to be active in neuron projection and synapse. Predicted to be integral component of plasma membrane. Is expressed in brain. Orthologous to human CHRNA9 (cholinergic receptor nicotinic alpha 9 subunit). [provided by Alliance of Genome Resources, Apr 2022]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
