UVR8 protein molecule. Computer model showing photoreception of UV-B (ultraviolet-B) light rays (top) by a UVR8 protein. The secondary structure (purple ribbons) of UVR8 is shown at bottom. UVR8 is a UV-B-sensing homodimer protein found in plants and possibly other sources. It is responsible for sensing ultraviolet light in the range 280-315 nanometre and initiating the plant stress response.
