The DNA repair synthesis complex, consisting of PCNA, RFC, RPA and polymerase delta (POLD) or epsilon (POLE) complexes, or polymerase kappa (POLK), is formed at the transcription coupled nucleotide excision repair (TC-NER) site, as well as the global genome nucleotide excision repair (GG-NER) site, following the incision of the damaged DNA strand 5' to the lesion by the ERCC1:ERCC4 (ERCC1:XPF) complex. 3' incision by XPG (ERCC5) is not required for the loading of the DNA polymerases and may not be required for the initiation of NER-mediated DNA synthesis (Staresincic et al. 2009). XPG and RPA promote the assembly of the DNA synthesis complex at the NER site (Mocquet et al. 2008).
