Intrinsically disordered regions (IDRs) are common in many proteins and functionally important in different contexts. IDRs are also important in driving liquid-liquid phase separation.

Characterizing the conformational sampling of IDRs is challenging both experimentally and computationally.

To  produce realistic ensembles of IDRs, we have focused on:

  • Improvement of atomistic force fields
  • Residue-level coarse-grained modeling
  • Generative modeling via machine learning

Scientific questions related to IDRs that we are interested in:

  • Residual internal structure
  • Scale-dependence of internal dynamics
  • Driving forces of condensation 

Software and modeling resources:

  • COCOMO: residue-based coarse-grained model of IDPs
  • idpgan: first generation generative modeling of IDPs trained on COCOMO or ABSINTH
  • idpsam: second generation generative modeling of IDPs trained on ABSINTH
