Identification of ADP-Ribose Acceptor Sites on In Vitro Modified Proteins by Liquid Chromatography–Tandem Mass Spectrometry
Protein ADP-ribosylation is a covalent, reversible posttranslational modification (PTM) catalyzed by ADP-ribosyltransferases (ARTs). Proteins can be either mono- or poly-ADP-ribosylated under a variety of phys...

Proteome-Wide Identification of In Vivo ADP-Ribose Acceptor Sites by Liquid Chromatography–Tandem Mass Spectrometry
ADP-ribosylation is a posttranslational modification (PTM) that affects a variety of cellular processes. In recent years, mass spectrometry (MS)-based proteomics has become a valuable tool for studying ADP-rib...

Open AccessProteome-wide identification of the endogenous ADP-ribosylome of mammalian cells and tissue
Although protein ADP-ribosylation is involved in diverse biological processes, it has remained a challenge to identify ADP-ribose acceptor sites. Here, we present an experimental workflow for sensitive and unb...
