EGFR and ErbB family
The Rizzo Group co-develops the DOCK program  and contributed to the latest to releases:
The release v6.4, greatly improved the sampling behavior with the inclusion of internal energy during growth and minimization. See release notes
The release v6.5 includes a new scoring function termed Footprint similarity score. See release notes
Docking Testset Development
| To facilitate the improvements to the DOCK codebase and docking protocols, our group has developed a docking testset for pose reproduction.

Docking Scoring Functions
Docking has two tasks: sampling and scoring. To Address scoring . . .
Receptor flexibility is important for docking to address this . . . MultiGrid Docking
Leveraging information from existing inhibitors is a useful paradigm for the discovery of new drugs. One scoring function developed in our group and emplemented in DOCK 6.5, footprint similarity (FPS) score, uses an energetic profile or footprint of, for example, a known drug to identify a ligand which make similar interactions and is thus likely to bind. Other ideas for computationally generated references include molecular dynamics weighted ensombles, transition states and more. We are expending this work on several levels including abstracting this scoring method to a grid-based method. See the following paper for more information on this topic.
