Function, Evolution, Structure of Co-chaperones Having a J-domain 

International workshop of the Cell Stress Society International (CSSI)

4-7 April 2018, Gdansk, Poland




Harm Kampinga (University Medical Center Groningen, The Netherlands) 

Elizabeth Craig (University of Wisconsin-Madison, USA)

About workshop:

The workshop is focusing on the functional/structural diversity of J-domain proteins across cellular compartments and organisms. The workshop will not only provide a unique opportunity to gather together those with a central interest in J-protein function, but also will create a platform for discussing a new J-protein classification scheme.

The workshop is kindly supported by the Cell Stress Society International (ISSI), the Intercollegiate Faculty of Biotechnology University of Gdansk and Medical University of Gdansk, the University Medical Center Groningen.

The limited space at the workshop is full.
