Protein dynamics was the first research to enchant me >10yrs ago, but I left in PhD bc I couldn't find big experimental data to evaluate models.

Today w @ginaelnesr.bsky.social, I'm thrilled to share the big dynamics data I've been dreaming of, and the mdl we trained w them: Dyna-1.

πŸ”₯ ProtComposer (ICLR'25 Oral) is a Swiss Army knife:

(i) Manually create new protein structure layouts? βœ…
(ii) Generation with favorable designability/diversity/novelty trade-offs? βœ…
(iii) Spatially edit given proteins? βœ…

Very original work by the amazing @hannes-stark.bsky.social and Bowen Jing!πŸ”₯

Here are images of the rest of the figures because why not.
(we also have classifier free guidance between the conditional and the unconditional model to trade off ellipsoid adherence or to recover the original model)

Our ellipsoid generation model is a simple statistical model => not overfit on the data => produces novel and diverse ellispoid layouts => ProtComposer produces novel and diverse proteins => nice pareto frontiers of designability vs. diverisity/novelty/helicity

The model just receives the ellipsoids as additional input information.

During training, the ellipsoids are extracted from the training structure (image).

During inference, the ellipsoids can be hand-specified, or come from data, or from our ellipsoid generative model.

We start with a protein structure generative model (MultiFlow) and finetune it to adhere to 3D ellipsoid layouts. The architecture is modified to process additional ellipsoid tokens and with an attention mechanism for 3D covariance matrices (that is how we represent the ellipsoids).

New paper (and #ICLR2025 Oral :)):
ProtComposer: Compositional Protein Structure Generation with 3D Ellipsoids arxiv.org/abs/2503.05025

Condition on your 3D layout (of ellipsoids) to generate proteins like this or to get better designability/diversity/novelty tradeoffs.
