Snowflake: A deep learning-based human leukocyte antigen matching algorithm considering allele-specific surface accessibility

By: Matthias Niemann, Benedict M. Matern, Eric Spierings

Published: in Frontiers in Immunology 2022.

Highlights:

  • Integrated deep learning protein surface prediction considering 676 HLA Class-I experimental structures and 37 Alphafold-predicted structures
  • Residues’ solvent-accessibility but not geometric position is protein-specific
  • Eplets in the HLA Epitope Registry show patterns of solvent-accessibility with
  • Consistently accessible residues
  • Only subsets of an epitope’s residues being consistently accessible
  • Varying surface accessibility of residues of epitopes
  • Calculation of donor-allele-specific solvent-accessible amino acid mismatches was implemented in the PIRCHE web service
