A big big good bye and a farewell to Christian Bippes. After having been for more than 8 years with the lab Christian decided to join Nanosurf, an AFM company close to Basel. After having beeing inspired by Christians art of cooking every labmember gave her/his best to prepare a speciality of the home country. It was a long evening we enjoyed Swiss, Italian, German, Spanish, Indian, Scottish, US, Argentinian, Chinese, Finnish, Armenian and Russian food. It was fantastic and Christian is welcome to join and leave the lab as often as he can ;-)) Best wishes from us all to Christian - it was wonderful having you as colleague!

Cells express and regulate membrane proteins to control whether or not, how strong and how long they adhere to the surfaces they encounter. Such cell adhesion molecules (CAMs) are membrane receptors that do not only form adhesive interactions, but also activate signal transduction pathways and regulate cellular processes. In regulatory processes termed ‘crosstalk’, CAMs regulate the activity of other CAMs. This allows the cell to actively adapt its adhesion properties to the environment. In a first attempt we develop a single-cell force spectroscopy (SCFS) based approach to initially characterize one such crosstalk pathway. This PhD project attempts to further develop and apply SCFS to characterize in depth how CAMs are regulated by crosstalk. In addition to the regulation of CAMs, the SCFS assays will allow us to determine how extracellular signals such as ligand-binding to membrane receptors regulate other receptors that control the adhesive properties of cells.
High-resolution microscopy (≈1nm) tools that allow the structural characterization of native membrane protein assemblies are rare. However, multifunctional high-resolution microscopic and spectroscopic approaches that allow to structurally observe the cell membrane and to simultaneously quantify their specific and unspecific interactions do not exist. In this PhD project we intend to develop and establish multifunctional high-resolution tools that allow to image single native membrane proteins of complex assemblies at subnanometer resolution and to quantify the interactions that guide the membrane protein assembly and function. We want to structurally map the interactions of membrane proteins with their environment and map the interactions inside membrane proteins that switch their functional state. Therefore we establish a new nanoscopic tool that images biological membranes at a resolution ≤ 1nm and simultaneously maps the interactions of the hosted membrane proteins in three dimensions. With this new multifunctional tool future researchers will be able to provide structural and quantitative insights into basic biological processes of the cell membrane.
We search for highly motivated candidates to work in an inspiring multidisciplinary field that combined engineering, biophysics, cell biology and molecular biology. The candidates should have a strong background in physics, biophysics and molecular biology. They will be coached by a vibrating consortium of international experts such as needed to perform an excellent PhD project.

The Biophysics group (Prof. D. J. Müller) at the D-BSSE, ETH Zürich, offers a position for a master thesis in the field of single-molecule biophysics and nanoscience.
The proposed project is based on our previous research on vertebrate cell-cell communication channels - connexins. This family of membrane proteins forms so-called gap junction communication channels. These channels are highly conserved and involved in many vital processes, such as action potential propagation in heart muscle and ion homeostasis. Connexin-based communication channels are regulated by various stimuli, such as pH or Ca2+. Recently, we could visualize gating of Connexin 26 (Cx26) by high-resolution atomic force microscopy (AFM) and showed that Cx26 hemichannels can undergo significant conformational changes at the extracellular surface.
During the last decade we established single-molecule force spectroscopy on membrane proteins. This approach allows deciphering intra- and intermolecular interactions of membrane proteins. By applying a mechanical stretching force unfolding of membrane proteins is induced. The force-distance relationship of the unfolding process quantifies and locates the interactions of the membrane protein. These interactions provide fundamental insight into how interactions switch the conformational and function of communication channels.
The aim of the offered master thesis project is to investigate the inter- and intramolecular interaction that switch human Cx26 communication channels from the open to the closed state. The experiments will be done with state-of-the-art single-molecule force spectroscopy.
