ProteomicsSerine ADP-ribosylation in Drosophila provides insights into the evolution of reversible ADP-ribosylation signaling
In the mammalian DNA damage response, ADP-ribosylation signaling is of crucial importance to mark sites of DNA damage as well as recruit and regulate repairs factors. Specifically, the PARP1:HPF1 complex recognizes damaged DNA and catalyzes the formation of serine-linked ADP-ribosylation marks (mono...

ProteomicsTemporal and site-specific ADP-ribosylation dynamics upon different genotoxic stresses
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 fu...

ProteomicsMapping physiological ADP-ribosylation using Activated Ion Electron Transfer Dissociation (AI-ETD)
ADP-ribosylation (ADPr) is a post-translational modification that plays pivotal roles in a wide range of cellular processes. Mass spectrometry (MS)-based analysis of ADPr under physiological conditions, without relying on genetic or chemical perturbation, has been hindered by technical limitations. ...

ProteomicsRegulation of Rad52-dependent replication fork recovery through serine ADP-ribosylation of PolD3
Although Poly(ADP-ribose)-polymerases (PARPs) are key regulators of genome stability, how site-specific ADP-ribosylation regulates DNA repair is unclear. Here, we describe a novel role for PARP1 and PARP2 in regulating Rad52-dependent replication fork repair to maintain cell viability when HR is dys...

ProteomicsChemical genetics and proteome-wide site mapping reveal cysteine MARylation by PARP-7 on immune-relevant protein targets
Poly(ADP-ribose) polymerase 7 (PARP7) has emerged as a critically important member of a large enzyme family that catalyze mono-ADP-ribosylation (MARylation) in mammalian cells. Unlike other PARPs, PARP7 is expressed in many different cell types and is upregulated by diverse stimuli, such as toxins, ...
