October 12, 2017

Today in the magazine Science, two very important papers appeared by Robert Tampé and by David Margulies  that solve a problem that many (including us) have thought about and worked on for a long time: the crystal structure of a class I molecule with a peptide editing chaperone. Thank you to both groups for illuminating this, I am very impressed and happy. The Margulies group have used our technique of dipeptide-induced class I refolding  to obtain their partially empty class I molecule.

November 3, 2016

We remember Stefan Jentsch who passed away last week. Stefan was a director at the Max Planck Institute for Biochemistry in T√ľbingen. After his postdoc with Alexander Varshavsky,¬†¬†he isolated the first ubiquitin conjugating enzymes from yeast and made very important contributions to the understanding of the big role that the ubiquitin system plays in protein degradation and in the supervision of the integrity of the genome.¬†Stefan¬†was the supervisor of Sebastian’s diplom (MSc) thesis at the Max Planck Institute in T√ľbingen.

As a student, I loved¬†Stefan’s anarchic and irreverent spirit, in science and life. In T√ľbingen, someone had hung up a poster in the hallway, showing a beautiful mountain lake in Switzerland. One day, I watched Stefan cut out from Post-It notes the parts of a giant sea snake monster and attach it to a corner of the lake, so people would see it at the second glimpse. At the time, it was shocking to me that a Professor would do such things. Stefan – you continue to inspire me to this day :-). Thank you.

October 12, 2016

I would like to congratulate our lab alumna Patrycja Kozik (BCCB class of 2004) on taking up her position as a Research Group Leader at the MRC Laboratory of Molecular Biology in Cambridge. She will work on antigen presentation through MHC class I in dendritic cells.
