Biochem/physiol Actions

PDD00017273 is a potent and selective inhibitor of Poly(ADP-ribose) glycohydrolase (PARG), which catalyses hydrolysis of the O-glycosidic linkages of ADP-ribose polymers, reversing the effects of poly(ADP-ribose) polymerases (PARPs). PARG has been shown to be involved in the repair of single strand DNA breaks. PDD00017273 is selective for PARG, with EC50 = 26 nM, compared to values of 30 μM for PARP1 and ARH3.
PDD00017273 is cell permeable in nature. It is used for specific killing of cells defective in certain homologous recombination (HR) proteins such as breast cancer gene 1/2 (BRCA1/2).

Upon genotoxic stress, PCNA ubiquitination allows for replication of damaged DNA by recruiting lesion-bypass DNA polymerases. However, PCNA is also ubiquitinated during normal S-phase progression. By employing 293T and RPE1 cells deficient in PCNA ubiquitination, generated through CRISPR/Cas9 gene editing

ARH3/ADPRHL2 and PARG are the primary enzymes reversing ADP-ribosylation in vertebrates, yet their functions in vivo remain unclear. ARH3 is the only hydrolase able to remove serine-linked mono(ADP-ribose) (MAR) but is much less efficient than PARG against poly(ADP-ribose) (PAR) chains in vitro.
