ADPr gets a ubiquitin upgrade - Nature Chemical Biology
MARUbylation is a hybrid post-translational protein modification in which mono-ADP-ribosylation acts as a scaffold for sequential mono- and polyubiquitylation. Recent studies illuminate its substrates...

At its core, it’s a technological paper—necessary to overcome some of the many challenges of working with ADPrUb. But beyond the technical details, below are the main highlights:

RNF114 is an E3 ligase that can recognize ADP-ribose (ADPr) and ubiquitin with separate domains. A proteomics approach is developed using these domains to map ADP-ribosyl-ubiquitylation sites

Thrilled to share my first first-author postdoc publication — a team effort with @aklvnbch.bsky.social. We present the first MS-based evidence of ADP-ribosylation–linked ubiquitin (ADPrUb) in cells after DNA damage.
Grateful for all I’ve learned and looking forward to uncovering more about ADPrUb

Really happy that our paper is finally released. We show that PARP1 and histones are targets of ADP-ribosyl-linked ubiquitylation during DNA damage and describe how to detect the dual modification. Great teamwork with @mariapalumbieri.bsky.social & thanks to everyone involved @maticlab.bsky.social !

We’ve uploaded a bioRxiv preprint on new antibodies specific for poly-ADP-ribosylation (PARylation). These modular tools were developed and validated through novel applications of our Serine ADP-ribosylation-based technology. www.biorxiv.org/content/10.1...
