Peptide-RNA photo-crosslinks with tunable RNA chain map protein-RNA interfaces Photo-crosslinking mass spectrometry enables the identification of protein-RNA interactions in living cells, pinpointing interaction interfaces at single-amino acid resolution. However, current isolat...

New preprint: We isolate peptide–RNA photo-crosslinks with tunable RNA chains from living cells for mass spec. This maps over 4,700 crosslinking sites across 744 proteins and offers the first glimpse into the RNA sequences in crosslinks by MS. Read here: doi.org/10.1101/2025...

What makes it even better: All experiments were performed in a dose-resolved manner—so you can dive into dose-response curves in our interactive dashboards! #CurveCurator #BeautifulCurves (3/4)

We explore how inhibition of oncogenic KRAS signaling reshapes protein phosphorylation, ubiquitylation, and protein expression—across multiple time points, using various KRAS inhibitors, as well as upstream and downstream pathway inhibitors, in different KRAS-mutant cell lines. (2/4)

🔎 To uncover the molecular mechanisms driving this synergy, we employed both chemo- and phosphoproteomics (decryptM), which revealed how ATR inhibition disrupts the DNA damage response when combined with gemcitabine. (3/4)

🧫 Using large-scale phenotypic drug screening, we identified promising drug combinations that enhance tumor cell death - and found Gemcitabine and ATR inhibitors to synergize most effectively. (2/4)

We'll DM you

Our tool was built using Vue.js and D3.js and is free for public reuse (github.com/kusterlab/bi..., github.com/wilhelm-lab/...).
Thanks to everyone involved! 🥳 We're looking forward to seeing how it'll be received by the community. (6/6).

If canonical pathway diagrams are not enough for you, just build your own! PTMNavigator's editing mode allows you to design custom pathways, tailored to your data and research question. 🧑‍🔬 (5/6)

What's more, we developed a server that runs various enrichment analyses on your data (github.com/kusterlab/en...) 🤓. The results of this are automatically integrated into PTMNavigator and help you figure out which pathways, proteins and PTM signatures are potentially relevant for your dataset.(4/6)

PTMNavigator projects your data onto interactive pathway diagrams, showing you where the hotspots of PTM regulation are. 🗺️ 📍 This can be used, for example, to contrast how two drugs affect the same pathway at different stages. (3/6)

Putting PTM data into context can be a daunting task, and it's easy to lose sight of the big picture. 👀
To tackle this, Julian Müller and colleagues have developed PTMNavigator, which is available at ProteomicsDB 💻 www.proteomicsdb.org/analytics/ptmNavigator (2/6)
