Use ParaSurf

Official Neurosnap webserver for accessing ParaSurf online.

Overview

ParaSurf is a deep learning framework that predicts paratope binding sites by analyzing molecular surfaces of antibodies/nanobodies to identify antigen-binding regions across the entire Fab/Fv domain. Combining geometric shape, chemical properties, and electrostatic force fields, ParaSurf employs a hybrid 3D ResNet-Transformer architecture to capture both local and global structural contexts. ParaSurf addresses class imbalance and generalizes to framework residues, enabling antigen-agnostic predictions for therapeutic antibody design and immune interaction studies.

Features

  • Predicts antibody-binding sites across the entire Fab region, including CDR loops and framework residues, using balanced sampling to mitigate class imbalance.
  • Integrates geometric, chemical, and electrostatic surface features (AMBER/CHARMM force fields) for comprehensive interaction modeling.
  • Employs a hybrid 3D ResNet-Transformer architecture to capture multi-scale spatial patterns from local atomic environments to global structural contexts.
  • Operates antigen-agnostically without requiring partner protein data, and provides open-source code for reproducibility and therapeutic development.
  • Achieves state-of-the-art performance on PECAN, Paragraph-expanded, and MIPE benchmarks (AUC-ROC score of 0.973 and AUC-PR score of 0.823).
