Research has provided new structural insight into UV-B-activated UVR8 bound to COP1. The study of UVR8 photoreceptors has implications for understanding responses to UV-B radiation, with findings suggesting UVR8 may have functions beyond canonical UV-B signaling. The specifics of UVR8's role and regulation, including its interactions and modifications, are being explored in various contexts, including plant species such as arabidopsis and rice.
