| Outline of Final Research Achievements |
G protein coupled receptors (GPCRs) are nature’s most versatile chemical sensors. There are over 600 GPCRs in the human genome and they respond to a broad spectrum of chemical entities ranging from photons, protons and calcium ions, to small organic molecules (including odorants and neurotransmitters), to peptides and glycoproteins. However, for 25% of GPCRs, endogenous ligands have not yet been identified. We would like to determine the structure of orphan receptor and search for the endogenous ligands based on these structures. To determine the structure of orphan receptor, we have tried to develop the monoclonal antibody recognizing the conformational epitope of receptor. As a result, several monoclonal antibodies recognizing the sequential epitope of orphan receptors have been screened.
