Reaction: Repair DNA synthesis of ~27-30 bases long patch by POLD, POLE or POLK in TC-NER
- in pathway: Gap-filling DNA repair synthesis and ligation in TC-NER
In transcription-coupled nucleotide excision repair (TC-NER), as well as in global genome nucleotide excision repair (GG-NER), the DNA synthesis complex (NER post-incision complex) consisting of PCNA, RPA, RFC and polymerase delta (POLD) or epsilon (POLE) complexes performs DNA repair synthesis after the damaged DNA strand is incised 5' to the lesion by the endonuclease complex ERCC1:ERCC4 (ERCC1:XPF) and 3' to the lesion by the endonuclease XPG (ERCC5). Depending on damage-induced PCNA monoubiquitination, DNA polymerase kappa (POLK) may also be involved in gap-filling DNA synthesis during nucleotide excision repair (NER) (Balajee et al. 1998, Staresincic et al. 2009, Ogi et al. 2010, Overmeer et al. 2011).
