| Research Abstract |
The purpose of this study is to develop a fluorescent protein-based red fluorescent Ca^<2+> sensor which can be excited by red light and emit red fluorescence. We generated a prototype red fluorescent Ca^<2+> sensor by replacing the circularly permuted GFP domain of G-CaMP2, which is our original green fluorescent Ca^<2+> sensor, with the circularly permuted RFP, then randomly mutagenized this prototype sensor and screened variants with high performance. As a result, we successfully found the sensor termed R-CaMP, which showed a great red fluorescence change upon Ca^<2+> binding.
