Bistable Red-Light Receptors Found in Mantis Shrimp Eyes
Start here
The research team analyzed 17 visual pigments in mantis shrimp eyes and found that 2 rhodopsins that absorb red light can be switched on and off by red and blue light. A total of 4 rhodopsins showed bistability, while 2 additional blue-light rhodopsins can be switched by blue and orange light. The study was published in Sci. Adv. (doi: 10.1126/sciadv.aef5666). Once optimized, these receptors could serve as optogenetic molecular switches for studying human G signaling pathways.
