A variety of photoreceptors and the frontiers of optogenetics.
Abstract:
Lives have acquired a variety of photoreceptive proteins which absorb light in the UV to far-red region during the evolution, such as many different types of rhodopsin, blue-light receptors including cryptochrome and phototropin, and red/far-red light photochromic phytochromes. After the long-time studies on the molecular mechanism of their action, they have been applied to various photobiological studies. Recent advancement in the research field is remarkable and brought many fruitful results especially in optogenetics. To introduce some of these results, we organized a symposium named “A variety of photoreceptors and the frontiers of optogenetics” at the 59th annual meeting of the Biological Society of Japan (BSJ) in November 2021. The symposium was co-organized by a research area of the Precursory Research for Embryonic Science and Technology Program (PRESTO) named “Optical Control”, directed by Prof. Shichida (Ritsumeikan University), sponsored by Japan Science and Technology Agency (JST). We invited 4 PRESTO members and 2 other researchers to cover the light absorption region from blue to far-red (Figure 1).
