  • involved in transcription-coupled repair (TCR) of oxidative lesions
  • RNA polymerase 2 transcription factor
  • plays a critical role in nucleotide excision repair (NER) and basal transcription
  • with ERCC3, are central genome caretakers involved in nucleotide excision repair (NER), although their respective role within this DNA repair pathway remains difficult to delineate
  • ERCC3 and ERCC2 are part of the TFIIH complex which mediates basal transcription and DNA nucleotide excision repair
