WebDec 20, 2024 · Poly (ADP-ribose) (PAR) polymerase 1 (PARP-1) and poly (ADP-ribosyl)ation (PARylation) are crucial mediators of these processes by affecting DNA/histone epigenetic events. DNA methylation/hydroxymethylation patterns and histone modifications are established by mutual coordination between all epigenetic modifiers. WebIn mammals, protein PARylation is performed by PAR polymerases (PARPs) ( 20 ). During DDR, upon detecting DNA lesions, PARP1 becomes active and promotes the formation of PAR chains on a number of targets including DTX2 ( 21, 22 ). Presumably, this functions as a signal to recruit DTX2 to DNA damage sites where it then ubiquitinates its targets.
