Abstract

ADP-ribosylation is a reversible post-translational modification with wide-ranging biological functions in all kingdoms of life. A variety of enzymes use NAD+ to transfer either single or multiple ADP-ribose (ADPr) moieties onto distinct amino acid substrates, often in response to DNA damage or other stresses. Poly-ADPr-glycohydrolase readily reverses poly-ADP-ribosylation induced by the DNA-damage sensor PARP1 and other enzymes, but it does not remove the most proximal ADPr linked to the target amino acid. Searches for enzymes capable of fully reversing cellular mono-ADP-ribosylation back to the unmodified state have proved elusive, which leaves a gap in the understanding of this modification. Here, we identify a family of macrodomain enzymes present in viruses, yeast and animals that reverse cellular ADP-ribosylation by acting on mono-ADP-ribosylated substrates. Our discoveries establish the complete reversibility of PARP-catalyzed cellular ADP-ribosylation as a regulatory modification.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
