New discovery reveals how two proteins collaborate to detect UV-induced DNA damage

Ultraviolet (UV) rays from sunlight can cause DNA damage that leads to skin aging and cancer. Fortunately, our bodies have a highly efficient repair system capable of swiftly identifying and repairing damaged DNA sites among approximately 3 billion base pairs. Recent research by a team at UNIST has shed new light on how this process operates at the molecular level.
