| Outline of Final Research Achievements |
We investigated the molecular basis of photoreception mainly in jumping spiders in order to understand the biological meanings and the diversity of UV reception in visual and non-visual animal photoreception. We conducted spectroscopic and biochemical analyses of visual pigments rhodopsins isolated from several species of jumping spider and other spiders and found the relationship between the spectral sensitivities of spider rhodopsins and the evolution of depth perception mechanism unique to jumping spiders. We also analyzed a non-visual photoreceptor protein peropsin of jumping spider and revealed that peropsin acts as a dark-active, light-inactivated G protein-coupled receptor, which is totally opposite activation manner from known photoreceptor proteins.
