Summary: This gene encodes a transmembrane protein that is the main subunit of the nucleotide-gated olfactory ion channel, which plays a key role in transducing chemosensory signal resulting from hydrogen sulphide exposure. Signaling pathways mediated by this gene operate in the cilia of type B cells. Knock out of this gene affects development of the olfactory epithelium and olfactory bulb.

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.
