Poly(ADP-ribosylation) of P-TEFb by PARP1 disrupts phase separation to inhibit global transcription upon DNA damage

open access: yesNature Cell Biology, 2022
DNA damage shuts down genome-wide transcription to prevent transcriptional mutagenesis and to initiate repair signalling, but the mechanism to stall elongating RNA polymerase II (Pol II) is not fully understood.

DNA ADP-Ribosylation Stalls Replication and Is Reversed by RecF-Mediated Homologous Recombination and Nucleotide Excision Repair

open access: yesCell Reports, 2020
Summary: ADP-ribosylation of proteins is crucial for fundamental cellular processes. Despite increasing examples of DNA ADP-ribosylation, the impact of this modification on DNA metabolism and cell physiology is unknown. Here, we show that the DarTG toxin-

Biallelic ADPRHL2 mutations in complex neuropathy affect ADP ribosylation and DNA damage response

open access: yesLife Science Alliance, 2021
This work studies known and new ADPRHL2 mutations with different disease mechanisms overall indicating that loss of nuclear ARH3 alone is pathogenic via dysregulated nuclear ADP ribosylation.

ADP-ribosylation of RNA in mammalian cells is mediated by TRPT1 and multiple PARPs

open access: yesNucleic Acids Research, 2022
RNA function relies heavily on posttranscriptional modifications. Recently, it was shown that certain PARPs and TRPT1 can ADP-ribosylate RNA in vitro. Traditionally, intracellular ADP-ribosylation has been considered mainly as a protein posttranslational

Selective monitoring of the protein-free ADP-ribose released by ADP-ribosylation reversal enzymes.

open access: yesPLoS ONE, 2021
ADP-ribosylation is a key post-translational modification that regulates a wide variety of cellular stress responses. The ADP-ribosylation cycle is maintained by writers and erasers.

The SARS-CoV-2 Nsp3 macrodomain reverses PARP9/DTX3L-dependent ADP-ribosylation induced by interferon signaling

open access: yesbioRxiv, 2021
SARS-CoV-2 non-structural protein 3 (Nsp3) contains a macrodomain that is essential for virus replication and is thus an attractive target for drug development.

The interplay of TARG1 and PARG protects against genomic instability

open access: yesCell Reports, 2023
Summary: The timely removal of ADP-ribosylation is crucial for efficient DNA repair. However, much remains to be discovered about ADP-ribosylhydrolases. Here, we characterize the physiological role of TARG1, an ADP-ribosylhydrolase that removes aspartate/

Cis- and trans-resveratrol have opposite effects on histone serine-ADP-ribosylation and tyrosine induced neurodegeneration

open access: yesNature Communications, 2022
Serum tyrosine levels increase during aging, neurocognitive, metabolic, and cardiovascular disorders. However, calorie restriction (CR) and sleep lower serum tyrosine levels.

BIOCHEMICAL AND STRUCTURAL STUDIES OF PATHOGEN EFFECTORS ASSOCIATED WITH UBIQUITIN ADP-RIBOSYLATION

open access: yes, 2023
Ubiquitination and ADP-ribosylation are reversible post-translational modifications involved in various cellular activities. Pathogens like Legionella pneumophila and Chromobacterium violaceum target host ubiquitin system via modifications involving ADP ...

A Study into the ADP-Ribosylome of IFN-γ-Stimulated THP‑1 Human Macrophage-like Cells Identifies ARTD8/PARP14 and ARTD9/PARP9 ADP-Ribosylation

open access: yes, 2019
ADP-ribosylation is a post-translational modification that, until recently, has remained elusive to study at the cellular level. Previously dependent on radioactive tracers to identify ADP-ribosylation targets, several advances in mass spectrometric ...
