| Research Abstract |
The metabolic pathway of visual chromophore in the insect retina has been investigated with particular focus on the following subjects, (1) identification of the protein that isomerizes all-trans retinoid to 11-cis form by light, and (2) metabolic pathway of the chromophore in the hemimetabolous insect. Researches in this project have elucidated that PDH, previously identified as a retina-specific oxidoreductase, is a strong candidate for a retinoid photoisomerase. In addition, HPLC-analyses of retinoid compositions in the light- and dark-adapted retinas of crickets uncovered their visual cycle and a novel protein involved in the cycle.
