Summary: Olfactory receptors interact with odorant molecules in the nose, to initiate a neuronal response that triggers the perception of a smell. The olfactory receptor proteins are members of a large family of G-protein-coupled receptors (GPCR) arising from single coding-exon genes. Olfactory receptors share a 7-transmembrane domain structure with many neurotransmitter and hormone receptors and are responsible for the recognition and G protein-mediated transduction of odorant signals. The olfactory receptor gene family is the largest in the genome. This olfactory receptor gene appears to represent a strain-specific polymorphic pseudogene in mouse, where some strains, including the C57BL/6 reference genome strain, have a non-functional allele, while other strains have a protein-coding allele.

What's a GeneRIF?

homo- and heterotypic adhesion between cells overexpressing the ORs MOR256-17 or M71, supporting the hypothesis that ORs may contribute to olfactory axon sorting by mediating differential adhesion between axons.
Title: Homotypic and heterotypic adhesion induced by odorant receptors and the β2-adrenergic receptor.
We show, in vivo, that the genetic replacement of the V1rb2 pheromone receptor coding sequence by an unrelated one from the odorant receptor gene M71 maintains gene exclusion, suggesting that a common mechanism is used to regulate their transcription.
Title: A common gene exclusion mechanism used by two chemosensory systems.
co-expression with three subtypes of purinergic receptor (P2Y(1)R, P2Y(2)R, and A(2A)R) resulted in markedly enhanced plasma membrane localization of M71
Title: Specificity of olfactory receptor interactions with other G protein-coupled receptors.

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.
