New version of TRAPP released
Researchers from the Molecular and Cellular Modeling (MCM) group at HITS released a new version of the TRAnsient Pockets in Proteins (TRAPP) webserver, available at https://trapp.h-its.org/.
The main new feature in TRAPP version 4 is the use of machine learning and molecular simulation to predict druggability, i.e. the ability to bind to a drug-like compound, of the protein binding site studied. In such a way, TRAPP facilitates the discovery of cryptic binding pockets that may not be apparent in the experimentally determined structure of a protein but that can be revealed when the protein motions are simulated.
The druggability score can help the user to easily identify the most druggable conformation of a given binding pocket from a set of conformations obtained from experiments or a molecular dynamics simulation. This predicted druggable conformation can then be used for drug design. TRAPP also includes visualization tools that enable the user to identify the factors affecting the predicted druggability of protein binding pockets.

About HITS
HITS, the Heidelberg Institute for Theoretical Studies, was established in 2010 by physicist and SAP co-founder Klaus Tschira (1940-2015) and the Klaus Tschira Foundation as a private, non-profit research institute. HITS conducts basic research in the natural, mathematical, and computer sciences. Major research directions include complex simulations across scales, making sense of data, and enabling science via computational research. Application areas range from molecular biology to astrophysics. An essential characteristic of the Institute is interdisciplinarity, implemented in numerous cross-group and cross-disciplinary projects. The base funding of HITS is provided by the Klaus Tschira Foundation.
