Usage and Biology
Fusion protein of [1] and [2]. This fusion protein PhyB-VP16 is an interaction partner of [3]. When crRNA and tracrRNA bind to Cas9, the protein is able to bind complementary DNA. When the system is exposed to red light (660 nm), the Phytochrome B receptor binds to the Phytochrome interaction actor (PIF). So it recruits the [4] protein. The PhyB-PIF binding can be abolished by illumination with far-red light (740nm.) This system enables activation of gene expression induced by red light.
