MGI Phenotype FUNCTION: 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. The nomenclature assigned to the olfactory receptor genes and proteins for this organism is independent of other organisms.

Nature of Mutation
DNA sequencing using the SOLiD technique identified a G to A transition at position 259 of the Olfr523 transcript in the single exon. The mutated nucleotide causes a valine to methionine substitution at amino acid 87 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).
Protein Function and Prediction
The Olfr523 gene encodes a 317 amino acid olfactory that belongs to the G-protein coupled receptor (GPCR) superfamily and contains the characteristic seven transmembrane domains.
The V87M change is predicted to be benign by the PolyPhen program.
