Analysis, prediction and visualization of molecular complexes Structural dynamics of G protein coupled receptors (GPCRs) Alzheimer's Disease

Our goal is to improve the understanding of proteins and their functions. Therefore we use knowledge based predictions of secondary and tertiary structure interactions of helical membrane proteins.
Furthermore, do we increase the explanatory power of protein models by fragment based modelling of proteins and protein complexes using Cryo-Electron Microscopy (EM) data as constraints.
In order to share our findings with the research community we are developing web applications for analysis, prediction and visualization of proteins and their complexes.

We work on the elucidation of the conformational space of GPCRs and its modulation by extracellular ligands and intracellular effector proteins by means of classical and umbrella sampling molecular dynamics simulations to address the issues of signaling specificity and biased signaling.
For this reason we are computational modelling receptor G protein or arrestin interactions to elucidate the mechanism of signal transduction.
