The fusion protein COP1-VP16 is an interaction partner of dCas9-UVR8. When crRNA and tracrRNA bind to Cas9, the protein is able to bind complementary DNA. If the system is exposed to UVB light (311 nm), the UVR8 receptor changes its configuration and recruits this COP1-VP16 protein. This activates gene expression induced by UVB light.

Biology and Usage

E3-ubiquitin ligase CONSTITUTIVELY PHOTOMORPHOGENIC 1 (COP1) is the interaction partner of ultraviolet B (UVB) light receptor UVR8 [1]. When UVB light is perceived by the UVR8 photoreceptor it monomerizes and therefore changes in its open confuguration. Then it recruits COP1.
