Welcome to ProteinLens

ProteinLens constructs a fully atomistic, energy-weighted graph representation of a biomolecular structure and explores the long-range communication or connectivity between any specific sites in the system. For example, it can be used to:

  • identify potential allosteric sites
  • explore allosteric pathways
  • identify residues that play a key role in signalling and/or cooperativity

The Background page provides insights into the theory behind ProteinLens, along with some recent examples of our work using the here presented approaches. This web-based application allows the construction and download of the graph corresponding to the structure of your choice, the interactive visualisation of residues relevant for communication within or across proteins and the download of complete results files. Visit the Tutorial page for a walk-through of the web interface, and the FAQ page if you get stuck!
