I hear so much about the growing power of predictive biology, especially in drug discovery and "co-folding". I want to see people put their GPU budget where their mouth is!

*Preprint Alert*: How do we measure resolution when biomolecules won't sit still? 🔬 Estimating it for a static cryo-EM reconstruction is standard. But what about a conformational ensemble? arxiv.org/abs/2606.14449 with the amazing henryhmattingly.bsky.social and @lukeevanshandle.bsky.social #cryoEM

New preprint is out ! Bad news : current all-atom simulations of phosphorylated IDPs are very probably wrong (and yes, this is clickbaity on purpose 😇) Good news : we know what to blame for it, and we even have an idea of how to fix it !

Excited to share our PEG model for disordered proteins in CALVADOS! If you are interested in exploring the effects of a crowder on the global dimensions of an IDP or want to explore the phase separation behaviour of a more weakly PS-prone IDP, have a look at our preprint and give it a try.

Check out @rasmusnorrild.bsky.social's work with Alex Buell and Joe Rogers developing and using Condensate Partitioning by mRNA-Display to probe phase separation of ~100.000 sequences, and @sobuelow.bsky.social's simulations to support and analyse the experiments www.biorxiv.org/content/10.1...
Figure 1a from the paper that outlines the method. Caption: "Peptides from the N-terminal IDR of DDX4 were encoded in a DNA library for mRNA display and transcribed using purified T7 RNA polymerase. The resulting mRNA contains a ribosomal binding site (RBS), a coding sequence (CDS) for peptide of interest, and a HA-tag for purification via the translated peptide. The synthetic mRNA (pink) is ligated to a puromycin-containing PEG-linker (black) containing a DNA sequence (blue) that forms a hetero duplex with the mRNA to facilitate single stranded RNA ligation. The resulting mRNA display molecule is purified using the HA-tag and added to an excess of DDX4N1 to measure partitioning of all library members through RNA/DNA sequencing. "

In our new paper we characterize the effects of indel variants on protein folding and stability using a new yeast-based protein folding sensor. The work was led by Sven Larsen-Ledet and supported by the @novo-nordisk.bsky.social. Link to paper: www.cell.com/structure/fu...

Systematic characterization of indel variants using a yeast-based protein folding sensor
Larsen-Ledet et al. developed a yeast-based protein folding sensor to determine the effects of indel variants in DHFR. Using a saturated indel library, it was found that most indels are not tolerated. Several are temperature sensitive and folding is rescued by methotrexate. Rosetta and AlphaFold2 predictions correlate with the observed effects.

Meet the CALVADOS RNA model Ikki Yasuda, Sören von Bülow & Giulio Tesei have parameterized a simple model for disordered RNA. Despite it's simplicity (no sequence, no base pairing) we find that it captures several phenomena that depend on the charge, stickiness and polymer properties of RNA 🧬🧶🧪
