Cancer

EGFR and ErbB family

Epidermal Growth Factor Receptor (EGFR) is a drug target for treating several types of Cancers, Including Lung and breast cansers. We are instested in targeting the Tyrosine kinase domain.

Method development

DOCK development

The Rizzo Group is a codeveloper of 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.
