The Viral Macrodomain Counters Host Antiviral ADP-Ribosylation [PDF]
Viruses, 2020 Macrodomains, enzymes that remove ADP-ribose from proteins, are encoded by several families of RNA viruses and have recently been shown to counter innate immune responses to virus infection.

Screening assay to monitor mono-ADP-ribosylhydrolase activity of viral macrodomains in cells [PDF]
Communications BiologyMono-ADP-ribosylation, a modification of both proteins and nucleic acids, is implicated in innate immunity. Intracellularly, this modification is catalyzed by PARP enzymes, some induced in response to interferons.

Mutations differentially affecting the coronavirus Mac1 ADP-ribose binding and hydrolysis activities indicate that it promotes multiple stages of the viral replication cycle [PDF]
Journal of VirologyAll coronaviruses (CoVs) encode a conserved macrodomain, termed Mac1, in non-structural protein 3 (nsp3) that binds and hydrolyzes ADP-ribose covalently attached to proteins.

Family-wide analysis of human macrodomains reveals novel activities and identifies PARG as most efficient ADPr-RNA hydrolase [PDF]
Communications BiologyADP-ribosylation is well-known as protein posttranslational modification and was recently also identified as RNA posttranscriptional modification. When macrodomain proteins were identified as protein ADP-ribosylhydrolases, several ADP-ribosylation ...
