WebJan 29, 2024 · PARylation is a transient and reversible protein post-translational modification that modulates the structural and functional properties of the acceptor proteins during a wide variety of biological processes including DDR, cell stress, transcription, immune response, aging and cell death [ 3, 4, 27 ]. WebAug 19, 2024 · PAR can be covalently attached to acceptor proteins, a widespread posttranslational modification (PTM) known as poly (ADP-ribosyl)ation (PARylation), or mediate the recruitment of DNA repair factors bearing PAR-binding modules to sites of DNA lesions via noncovalent interactions [ 24, 25 ].

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.
