Structure-Guided Adaptive Propagation for Protein-Protein Interaction Site Prediction

Researchers introduce SGAP-PPIS, a graph neural network model that uses adaptive propagation guided by protein structure geometry to predict protein-protein interaction sites more accurately. The model dynamically adjusts how information flows between residues based on their local geometric environment, outperforming fixed propagation approaches in distinguishing true interaction sites from similar non-interacting regions.

Learning Implicit Bias in Generative Spaces for Accelerating Protein Dynamics Emulation

Researchers have developed a method to enhance generative AI models that simulate protein dynamics by introducing a history-dependent bias that steers sampling toward undiscovered molecular states. The technique achieves 37× faster coverage of low-energy protein configurations compared to standard approaches, significantly improving the practical utility of AI-accelerated molecular simulation.

From Holo Pockets to Electron Density: GPT-style Drug Design with Density

Researchers introduce EDMolGPT, a generative AI model that uses electron density data from protein binding pockets to design novel drug molecules. The approach improves upon existing methods by incorporating physically grounded density information rather than empty pocket structures, enabling more accurate molecular generation with realistic 3D conformations.

Cryo-SWAN: the Multi-Scale Wavelet-decomposition-inspired Autoencoder Network for molecular density representation of molecular volumes

Researchers developed Cryo-SWAN, a new AI autoencoder network that uses wavelet decomposition to better represent 3D molecular structures from cryo-electron microscopy data. The model outperforms existing 3D autoencoders on multiple datasets and can integrate with diffusion models for molecular shape generation and denoising.

Protein Structure Tokenization via Geometric Byte Pair Encoding

Researchers have developed GeoBPE, a new protein structure tokenization method that converts protein backbone structures into discrete geometric tokens, achieving over 10x compression and data efficiency improvements. The approach uses geometry-grounded byte-pair encoding to create hierarchical vocabularies of protein structural primitives that align with functional families and enable better multimodal protein modeling.

Representing local protein environments with atomistic foundation models

Researchers developed a novel method to represent local protein environments using atomistic foundation models (AFMs), creating embeddings that capture both structural and chemical features. The approach enables construction of data-driven priors for biomolecular environments and achieves state-of-the-art accuracy in physics-informed chemical shift prediction for NMR spectroscopy.
