| Research Abstract |
It was reported that mRNA of an opsin, encephalopsin has been identified in brain of mammalian and non-mammalian vertebrates and therefore it is of interest to elucidate whether it actually serves as a light-sensor. In vitro experiments suggested that a member of encephalopsin group could act as a light-sensing G protein-coupled receptor. We successfully prepared transgenic mice that express green fluorescence protein(GFP) under regulation of upstream of encephalopsin gene and found GFP expression in the brain cells. The mice could facilitate to specifically isolate encephalopsin-expressing cells and characterize its photosensitivity.
