Arrest of transcription at sites of DNA damage represents a strong signal for apoptosis. To overcome the impasse represented by transcription complexes arrested at sites of damage, cells have evolved a specialized nucleotide excision repair (NER) pathway called transcription-coupled DNA repair (TCR), dedicated to removal of transcription-blocking lesions from the genome. This repair pathway was discovered in Phil Hanawalt's laboratory 20 years ago, but the mechanistic details are still subject of intense research. This article will review the recent literature on the subject with emphasis on how lesions affect the elongation step of transcription and how the initial steps of TCR occur in human cells.
