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 T to A transversion at position 422 of the Olfr181 transcript, in exon 2 of 2 total exons. The mutation causes an isoleucine to lysine change at amino acid 15 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (see trace files for B5639).

Protein Function and Prediction

The 317 amino acid olfactory receptor 181 (Olfr181) is a potential odorant receptor belonging to the seven transmembrane G-protein coupled receptor family (Uniprot Q8VGQ7). Its N and C termini are positioned extracellularly and intracellularly, respectively.

The mutation lies in the extracellular N-terminal segment of the protein, and is predicted to be benign by the PolyPhen-2 program.
