Binding of XP-C:RAD23B complex to the damaged site on the DNA substrate is followed by recruitment of XP-A and the RPA heterotrimer, initiating formation of the incision complex. This includes a serial assembly of the remainder of the NER (nucleotide excision repair) machinery consisting of TFIIH, XPG, SNM1 family proteins etc. The action of DNA helicases in the TFIIH complex partially denatures the DNA template generating a bubble structure and exposing a fragment of ssDNA containing the lesion for endonuclease activity. The subsequent events involving, formation of an active incision complex around the bubble structure by specific NER endonucleases and leading to the excision of ~27 30 bp of damaged ssDNA are not well characterized in chicken.
