title: Mechanisms of transcription-coupled DNA repair.
abstract: Several types of helix-distorting DNA lesions block the passage of elongating RNA polymerase II. Surprisingly, such transcription-blocking lesions are usually repaired considerably faster than non-obstructive lesions in the non-transcribed strand or in the genome overall. In this review, our knowledge of eukaryotic transcription-coupled repair (TCR) will be considered from the point of view of transcription, and current models for the mechanism of TCR will be discussed.
