Abstract excerpt
The Cockayne syndrome B protein (CSB) has long been known to be involved in the repair of DNA modifications that block the RNA polymerase in transcribed DNA sequences (transcription-coupled repair). Recent evidence suggests that it also has a more general role in the repair of oxidative DNA base modifications such as 7,8-dihydro-8-oxo-2'-deoxyguanosine (8-oxoG). In mammalian cells, 8-oxoG is a substrate of the...
