Structure and Function of Membrane Proteins
Membrane proteins are mediators of essential processes in the cell such as solute transport, electrical excitability and signaling. Atomistic insight into the architecture of membrane proteins, their conformational breadth and precise functioning is essential in fundamental research. Since membrane proteins are major targets of small molecule drugs these insights are also necessary for the treatment of life-threatening diseases. In the Brunner lab we study the structure and function of membrane proteins, with a particular emphasis on lipid biology and ion channels in membrane transport.
Lipid transporters and membrane asymmetry
Our knowledge on the composition and architecture of biological membranes has grown substantially in the past decades. However, we are just beginning to functionally and structurally characterize the molecular identities that underlie the complex organization of bilayers.
One important feature of biomembranes is the asymmetric distribution of specific lipids between the two leaflets of the bilayer. This distribution is also subject to dynamic changes and serves important functions. For instance, exposure of phosphatidylserine to the extracellular leaflet– normally confined to the intracellular leaflet of the plasma membrane in the resting state – is a crucial event in processes as diverse as apoptosis, blood clotting, bone mineralization, myoblast fusion and in cell to cell spreading of viruses (apoptotic mimicry).

We are always on the lookout for highly motivated colleagues to join our team. If you are interested, please contact us.
The Janine Brunner Lab can only thrive thanks to the dedication and commitment of its people, no matter what their function or seniority.
To stay up to date in rapidly developing fields, scientists regularly interact with (international) colleagues. Conferences and other (scientific) events are an excellent way to facilitate such a continent-spanning knowledge exchange.
