G protein-coupled odorant receptors underlie mechanosensitivity in mammalian olfactory sensory neurons.
Mechanosensitive cells are essential for organisms to sense the external and internal environments, and a variety of molecules have been implicated as mechanical sensors. Here we report that odorant receptors (ORs), a large family of G protein-coupled receptors, underlie the responses to both chemical and mechanical stimuli in mouse olfactory sensory neurons (OSNs). Genetic ablation of key sign...
متن کاملFunctional Evolution of Mammalian Odorant Receptors
The mammalian odorant receptor (OR) repertoire is an attractive model to study evolution, because ORs have been subjected to rapid evolution between species, presumably caused by changes of the olfactory system to adapt to the environment. However, functional assessment of ORs in related species remains largely untested. Here we investigated the functional properties of primate and rodent ORs t...

متن کاملFunctional Expression of Mammalian Odorant Receptors
The olfactory sensory neurons (OSNs) in the olfactory epithelium of the nose detect and discriminate a large number of volatile environmental chemicals. This ability is essential for animals to find prey, food, mates, predators and toxic compounds. In OSNs, odorant receptor (OR) proteins, members of the G-protein coupled receptor (GPCR) superfamily, are concentrated at the membrane of the cilia...
متن کاملRTP Family Members Induce Functional Expression of Mammalian Odorant Receptors
Transport of G protein-coupled receptors (GPCRs) to the cell surface membrane is critical in order for the receptors to recognize their ligands. However, mammalian GPCR odorant receptors (ORs), when heterologously expressed in cells, are poorly expressed on the cell surface. Here we show that the transmembrane proteins RTP1 and RTP2 promote functional cell surface expression of ORs expressed in...
