Mono-ADP-ribosylation as a degradation mark? @andriigorelik.bsky.social, Ivan Ahel et al observe increased ADP-ribosylation of aryl hydrocarbon receptor (AHR) & PARP7 upon ubiquitin-proteasome blockage, crosstalk with DTX2 E3, as rapid AHR-transcription off-switch www.embopress.org/doi/full/10....

The interplay between ADP-ribosylation and ubiquitination, mediated by PARP7 and DTX2 proteins, can serve as a rapid AHR transcription “off-switch” through proteasomal degradation. www.embopress.org/doi/full/10....

Akin to bacterial SIR2 antiphage proteins, human SIRal, also known as FAM118b, forms filaments that are essential for its NAD processing activity. Awesome to see structures of these filaments that differ from bacterial ones. Congrats to the authors on this beautiful study.

Very happy to share our collaborative project on FAM118 proteins - noncanonical sirtuins that form filaments and process NAD in human and other vertebrate cells.

Please check our collaborative paper with Marcin Suskiewicz and Sebastien Huet labs on FAM118 proteins – non-canonical sirtuins that form filaments and act as NADases in human and other vertebrate cells. www.nature.com/articles/s41...

Here you can read our full review paper on the interplay between ADP-ribosylation and ubiquitination, with special focus on dual, hybrid modification ADPr-Ub: pubmed.ncbi.nlm.nih.gov/41065402/

This News & Views article provides a nice overview of the recent discoveries that RNF114 recognizes a dual modification ADP-ribose–ubiquitin (ADPr-Ub) and subsequently extends it by adding additional ubiquitin units.: pubmed.ncbi.nlm.nih.gov/41039156/

RNF114 and RNF166 exemplify a new E3 ligases family that recognizes #MARUbylation –hybrid ADP-ribose/ubiquitin modifications– and extends them with K11-linked polyubiquitin @jnpruneda.bsky.social @michaelnadbio.bsky.social and colleagues www.embopress.org/doi/full/10....
