Molecular Modelling Of Ion Channels

We use computational methods (including homology modelling, molecular dynamics simulations, docking investigations etc.) to explore the relationship between structure, function and dynamics of ion channels. We currently focus on several distinct ion channel families including K+, Ca2+ and Nav channels.
The three-dimensional architecture of several of these channels has been revealed by X-ray crystallography allowing detailed insights into the structure of these channels. Although there is an increasing amount of structural information available, many questions concerning the dynamics associated with gating, selectivity and ligand binding remain unknown.
Computer simulations allow us to simulate the motions of these proteins and to explore the relationship between (static) structure and dynamic function.
