transcription-coupled nucleotide-excision repair, DNA damage recognition complex
transcription-coupled nucleotide-excision repair, dna damage recognition complex
"A protein complex that is capable of identifying lesions in DNA on the actively transcribed strand of the DNA duplex as well as a small subset of lesions not recognized by the general nucleotide-excision repair pathway. The wide range of substrate specificity suggests that the repair complex recognizes distortions in the DNA helix. It subsequently recruits a nucleotide-excision repair, preincision complex."
