Photosensitivity syndrome brings to light a new transcription-coupled DNA repair cofactor

Abstract:
Three teams have applied whole-exome and proteome methods to identify a new cofactor of human RNA polymerase II that is required for the recovery of transcription on damaged templates. The identification of this new factor raises questions about the causal relationships between molecular mechanisms of transcription regulation and excision repair and developmental and neurological disease and nonmalignant skin photosensitivity.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
