Scientific Report on TUM-IAS Fellowship
The TUM-IAS Focus Group Structural Membrane Biochemistry works on the development of tools for the high-resolution structure determination of membrane proteins in a native lipid bilayer environment by nuclear magnetic resonance (NMR) spectroscopy and other structural methods. Since membrane proteins are very difficult to study with structural methods, advanced strategies are required. full report

Research Interests
Prof. Hagn's research is focused on nuclear magnetic resonance (NMR) spectroscopy of membrane proteins. This protein class is essential for signal transduction and the transfer of proteins and small molecules across the biological membrane barrier. The key to understanding these processes is to study these systems in a native environment provided by a phospholipid bilayer. Biologically relevant systems of interest are mitochondrial membrane proteins, G-protein coupled receptors (GPCRs) and their associated G-proteins, which are involved in metabolic diseases, neurological disorders and cancer.
