Multiscale guidance of AlphaFold3 with heterogeneous cryo-EM data

  • Protein structure prediction models can now generate accurate 3D structural hypotheses from sequence alone.
  • Cryo-electron microscopy (cryo-EM) has become a powerful tool for imaging near-native structural heterogeneity.
  • A new method, CryoBoltz, combines cryo-EM density maps with sequence and biophysical priors to guide protein structure prediction models, allowing accurate prediction of dynamic biomolecular complexes.
  • CryoBoltz demonstrates the ability to build atomic models into heterogeneous cryo-EM maps for various biomolecular systems like transporters and antibodies.
