KING NEWS ***BREAKING

19.5.2017: Harry wins poster price at the 13th Yeast Lipid Conference in Paris. The conference lipid scientists from around the globe. Harry is a fellow of the Austrian Science Fund FWF and is working on the specificity of protein-lipid and protein-membrane interactions. Great stuff, Harry!

10.5.2017: Check out our new lab in Homburg. A photo of our new lab space can be seen in the Campus journal by the University of Saarland here.

15.4.2017: Robert is featured by the Journal of Cell Science as 'Cell Scientists to Watch'. Read about his motivation, path, and hobbies in the current issue of the journal here

1.4.2017: Our proposal "Design principles of living membranes" for the funding scheme "Life?" by the VW foundation has been rewarded with a research grant! It is a joint project with our dear friends Ilya Levental (UTH Houston, Texas, USA), James Sáenz (TU Dresden, GER) and Maya Schuldiner (Weizmann Institute, Tel Aviv, ISR). Fantastico! Go team, go!

Does a cell have machineries to specifically degrade or sequester aberrant membranes?

In the past decades elaborate networks of chaperones were identified to guarantee proper protein folding. Cells counteract the accumulation of misfolded proteins using various strategies that either rebuilt or remove protein aggregates. But how does a cell handle aberrant membrane structures such as ER-whorls, hexagonal phases, or tightly packed membrane stacks?

Upon membrane stress the nuclear envelope forms membrane extrusions and whorl-like structures (white arrows). Electron micrographs of yeast cells after high-pressure freezing were kindly provided by Daniela Vorkel.
