Usage and Biology

Fusion protein of PhyB and VP16. This fusion protein PhyB-VP16 is an interaction partner of dCas9-PIF. 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 dCas9-PIF 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. Have a look at our [http://2013.igem.org/Team:Freiburg/Project/induction#light light project page].
