Post-translational modifications of proteins by polymers of ADP-ribose (PAR) or by phosphorylation allow the assembly of DNA repair protein complexes at damaged chromatin and are crucial to ensure genome stability. In response to DNA insults, the synthesis of PAR by the PARP1 and PARP2 proteins is strongly induced. PAR act as a signaling platform for the recruitment of multiples proteins at the sites of DNA damages, including the scaffold protein XRCC1. Research conducted during this PhD have been focused on studying the regulation of PARP1 and PARP2 functions in double-strands break repair (DSBR), and in investigating the role of XRCC1 modifications by phosphorylation in response to DNA damage.Using DNA repair assay allowing us to assess t...
