Excited to share our latest study in Nature Communications ✨

We map how cells clear DNA damage–stalled RNA polymerase II using a stepwise TFIIH β†’ ubiquitin/VCP mechanism, keeping transcription and genome stability on track.

Interested in antisense oligonucleotides?
Check our story about downstream-of-gene ASOs (DG-ASOs)!
Together with the Roche Innovation Center we
identified transcription termination windows of protein-coding genes as ASO target regions.

The sequence context of RG/RGG motifs determines condensate formation, transportin-1 binding and chaperoning Intrinsically disordered arginine-glycine-rich (RG/RGG) regions are highly abundant in the eukaryotic proteome. Proteins containing these motifs participate in fundamental cellular processes, including nuclear import, transcriptional regulation, biomolecular condensate formation, and apoptosis. Mutations or dysfunction of RG/RGG proteins have been implicated in neurodegenerative diseases and cancer. Although some RG/RGG proteins have been shown to drive condensate formation, localize to membrane-less organelles, interact with nuclear import receptors, or undergo arginine methylation, these properties are not shared uniformly across the proteome. The considerable diversity in RG/RGG motif length and amino acid composition raises the question of which sequence features determine their functional behaviour. To address this, we conducted a systematic bioinformatics and experimental analysis, combining synthetic and natural peptides with studies on the RNA-binding protein FUS as a model system. Our results reveal that the sequence composition of RG/RGG motifs is a key determinant of their capacity for RNA-mediated condensate formation, stress granule recruitment, and transportin-1–mediated chaperoning and nuclear import. These findings provide new insight into the sequence grammar of disordered RG/RGG regions and how it encodes the multifunctionality of these proteins in cellular regulation. ### Competing Interest Statement The authors have declared no competing interest.

We thought we knew how DNA repair worked. We were wrong.

Want to get the data out of a PDF figure? As in, the actual data – not a rough trace-along-the-lines version?

Energy-landscape model of RF2 activation. Comparison of termination complexes (TC), wild-type ArfA-bound nonstop elongation complexes (nsECs), and loss-of-function ArfA mutant-bound nsECs reveals that wild-type ArfA promotes RF2 docking to nsECs by reshaping the conformational cascade.

Slightly overdue article highlight!

In PNAS, we use smFRET to reveal how polypeptide release factor 2 (RF2) undergoes a cascade of structural changes to catalyze polypeptide release during translation termination and ArfA-mediated ribosome rescue.

These effects can translate in vivo...
