Title	Temporal and site-specific ADP-ribosylation dynamics upon different genotoxic stresses
Description	The DNA damage response revolves around transmission of information via post-translational modifications, including reversible protein ADP-ribosylation. Here, we applied a mass spectrometry-based Af1521 enrichment technology for the identification and quantification of ADP-ribosylation sites as a function of various DNA damage stimuli and time. In total, we detected 1,681 ADP-ribosylation sites residing on 716 proteins in U2OS cells, and determined their temporal dynamics after exposure to the genotoxins H2O2 and MMS. Intriguingly, we observed a widespread but low-abundant serine ADP-ribosylation response at the earliest time point, with later time points centered on increased modification of the same sites. This suggests that early serine ADP-ribosylation events may serve as a platform for an integrated signal response. While treatment with H2O2 and MMS induced homogenous ADP-ribosylation responses, we observed temporal differences in the ADP-ribosylation site abundancies. Exposure to MMS-induced alkylating stress induced the strongest ADP-ribosylome response after 30 minutes prominently modifying proteins involved in RNA processing, whereas in response to H2O2-induced oxidative stress ADP-ribosylation peaked after 60 minutes, while mainly modifying proteins involved in DNA damage pathways. Collectively, the dynamic ADP-ribosylome presented here provides valuable insight into the temporal cellular regulation of ADP-ribosylation in response to DNA damage.
