Predicting conformational changes induced by biomolecular interactions

Biomolecular interactions trigger structural changes of protein complexes essential for cellular signaling, regulation, and drug action [1–4]. Modern co-folding models can now generate detailed structures of multi-component complexes directly from sequence [5–9]. However, recent evaluations reveal that they frequently...

Blending experimental electron density information to protein-ligand interaction

Machine learning models for protein-ligand interactions commonly rely on atomic coordinates, which are constructed by fitting molecular models to experimental electron-density maps. However, most models represent each complex as a single fitted structure, which can omit information about conformational heterogeneity, p...

scTrilemma: Balancing Identity, Invariance, and Fidelity in Single-Cell Representation Learning

Single-cell RNA-seq representation learning is fundamentally label-free: cell identities, states, and contexts are not fixed training targets, so what constitutes signal or nuisance is analysis-dependent. A single representation must therefore preserve biological identity and state, remain robust to nuisance context, a...
