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 an A to T transversion at position 514 of the Olfr794 transcript. The mutated nucleotide causes an isoleucine to phenylalanine substitution at amino acid 172 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).
Protein Function and Prediction

The Olfr794 gene encodes the 320 amino acid olfactory receptor 794. Olfactory receptors are G-protein coupled receptors (GPCRs) and usually contain seven transmembrane domains.

The I172F change is predicted to be probably damaging by the PolyPhen program.
