Quantitative super-resolution microscopy unravels nanoscale patterns of membrane receptor networks

Principle Investigator: Prof. Dr. Mike Heilemann

Research Areas: Structural cell biology

Summary

We investigate the structure-function relationships of membrane-associated protein assemblies in the natural environment of a cell. We decipher the composition of multiprotein membrane receptor complexes which build active signaling platforms and characterize protein-protein interactions that regulate information transmission. To this end, we employ super-resolution optical microscopy methods to visualize the structural organization and to quantify the composition of multiprotein assemblies at the plasma membrane of cells. We will capture the assembly dynamics in living cells.
