The regulatory landscape of the human HPF1- and ARH3-dependent ADP-ribosylome
Abstract
ADP-ribosylation is regulated by HPF1 and ARH3, but the cellular target spectrum of these enzymes is not fully understood. Here, the authors use quantitative proteomics to define the HPF1- and ARH3-dependent ADP-ribosylome, providing evidence that mono-ADP-ribosylation of serine predominates in cells.
