Structure and mechanism for DNA lesion recognition.
A fundamental question in DNA repair is how a lesion is detected when embedded in millions to billions of normal base pairs. Extensive structural and functional studies reveal atomic details of DNA repair protein and nucleic acid interactions. This review summarizes seemingly diverse structural motifs used in lesion recognition and suggests a general mechanism to recognize DNA lesion by the poor base stacking. After initial recognition of this shared structural feature of lesions, different DNA repair pathways use unique verification mechanisms to ensure correct lesion identification and removal.
