PhyB-PIF3 phytochrome-based optogenetic tool
Multi-Component SwitchPhyB-PIF3 is a phytochrome-based multi-component optogenetic switch implemented in Caenorhabditis elegans for red/near-infrared light control of cell signaling. In the cited study, photoswitching of the PhyB-PIF3 pair was supported by endogenously produced phycocyanobilin supplied by the SynPCB biosynthesis system.
