ADP-ribosylation is essential for cell function, yet there is a dearth of methods for detecting this post-translational modification in cells. Here, we describe a clickable aminooxy alkyne (AO-alkyne) probe that can detect cellular ADP-ribosylation on acidic amino acids following Cu-catalyzed conjugation to an azide-containing reporter. Using AO-alkyne, we show that PARP10 and PARP11 are auto-ADP-ribosylated in cells. We also demonstrate that AO-alkyne can be used to monitor stimulus-induced ADP ...[more]
