Scatter plot of LDDT as a function of sequence identity for high coverage homology models. The horizontal red line at 40% sequence identity highlights the presence high quality models in the low sequence identity region.

Filtering out homologous structures from the PDB at 40% sequence identity is not enough to create a robust test set. Significant leakage persists at this level, and comparative modeling can still produce high quality models.

Scaling down protein language modeling with MSA Pairformer Recent efforts in protein language modeling have focused on scaling single-sequence models and their training data, requiring vast compute resources that limit accessibility. Although models that use ...

TLDR: We introduce MSA Pairformer, a 111M parameter protein language model that challenges the scaling paradigm in self-supervised protein language modeling🧡

Rational engineering of allosteric protein switches by in silico prediction of domain insertion sites - Nature Methods ProDomino is a machine leaning-based method, trained on a semisynthetic domain insertion dataset, to guide the engineering of protein domain recombination.

Our work on rationally engineering allosteric protein switches is now out in Nature Methods: www.nature.com/articles/s41... Thanks a lot to @grunewald.bsky.social and @noahholzleitner.bsky.social for the comprehensive news and views: www.nature.com/articles/s41...

Can an AI model predict perfectly and still have a terrible world model?

What would that even mean?

Our new ICML paper (poster tomorrow!) formalizes these questions.

One result tells the story: A transformer trained on 10M solar systems nails planetary orbits. But it botches gravitational laws 🧡

We will be hosting a mirror site of the CASP data and workflows at @sib.swiss. Operating a redundant site with independent funding is a good idea for important scientific infrastructure, independent from the current funding situation in the US.

I had the honor of receiving both the Otto Hahn Medal and Award of the May Planck Society. I am looking forward to transforming this chance into an own research group pushing the boundaries of interdisciplinary phage research!

πŸ§ͺ New preprint: "Generative Modeling of Full-Atom Protein Conformations using Latent Diffusion on Graph Embeddings"

We generate complete, all-atom protein conformational ensembles, capturing both backbone and side-chain dynamics of, e.g., the Dopamine D2 receptor.

Protein design and optimization for synthetic cells Nature Reviews Bioengineering, Published online: 19 May 2025; doi:10.1038/s44222-025-00318-1Bottom-up synthetic biology might greatly benefit from custom-made proteins as components of new biological systems. This Review discusses various protein optimization and design approaches, and explores how these can contribute to the generation of controllable synthetic cells.

Inverse folding NNs are better at predicting changes to a mutated protein's equilibrium dynamics, relative to WT, than protein folding NNs (BioEmu & AF-Cluster). This was shown on an enzyme that is more enzymatically promiscuous in the open state.

TFW you realize that you built a *bunch* of models using sklearn's RandomForestRegressor using default params, which, of course, means that you didn't actually build random forests. 🀦

Ah well, they don't take that long to build and the real random forests build even faster.
