Reaction: PARP1 or PARP2 PARylates DDB2 and autoPARylates

- in pathway: DNA Damage Recognition in GG-NER
PARP1 and/or PARP2 homo- or heterodimers recruited to global genomic nucleotide excision repair (GG-NER) site poly(ADP)ribosylate (PARylate) DDB2 and also progressively autoPARylate. PARylation promotes retention of DDB2 at DNA damage sites (Pines et al. 2012, Robu et al. 2013).
