| Outline of Final Research Achievements |
We have established a novel DNA aptamer screening method utilizing the physiological functions of GPCRs to develop DNA aptamers targeting G protein coupled receptors (GPCRs). As a result of many studies, this method was more sensitive and efficient than Cell SELEX method. As a result of a search using this screening technology, we obtained a DNA aptamer, designated Apt-MOR, which recognized MOR opioid receptor, an analgesic-related GPCR. This DNA aptamer bound specifically to MOR with high affinity and functioned as an agonist for MOR. Therefore, this novel screening method and Apt-MOR DNA aptamer can be available tools for developing analgesic drug discovery technology.
