| Research Abstract |
In this study, we found a novel rhodopsin and a novel light-signaling system in eyes of cnidarian, which is one of most primitive animals withdeveloped eyes, suggesting an evolutional linkage between rhodopsins and photoreceptorcell-types. We also comparatively analyzed rhodopsins in pineal organs of lowervertebrates and suggested that vertebrate visual pigments might promote molecularevolution of light-signaling proteins. In addition, our analyses on lizard parietal eyessuggest that two kinds of rhodopsins co-operatively function in a single photoreceptor cell.
