GRK2243 Symposium

Understanding Ubiquitylation:

From Molecular Mechanisms to Disease

9-11 May 2022 I Würzburg, Germany 

The Meeting

The Meeting

The post-translational modification of proteins with ubiquitin ("ubiquitylation") has taken center stage in eukaryotic cell biology. Ubiquitylation mediates the degradation of regulatory and damaged proteins, protein aggregates and even entire organelles. Moreover, it controls a wide variety of non-proteolytic processes, e.g. during DNA damage repair, receptor signaling and endocytosis.


Given the multi-faceted cellular functions of protein ubiquitylation, it is not surprising that abnormalities of the ubiquitin system lead to many human diseases including cancer, neurodegenerative disorders and infectious diseases. Moreover, the ubiquitin system has emerged as a promising target for therapeutic intervention, and drugs interfering with ubiquitin-mediated proteolysis are successfully used for the treatment of certain cancers. 


This Symposium aims to showcase the most recent, exciting progress towards understanding molecular mechanisms, cellular functions and pathogenic aberrations of the ubiquitin system as well as developing novel therapeutic strategies targeting it. The meeting will feature cutting-edge research presentations by international leaders in the field, additional short talks selected from submitted abstracts, and a large poster session along with poster teasers. There will be ample opportunity for scientific interactions between all participants to stimulate further progress in ubiquitin research.


The Symposium is organized by the Research Training Group GRK2243, a ubiquitin-themed graduate program, which has been funded by the German Research Foundation DFG since April 2017. The GRK2243 offers cutting-edge research projects and a structured, interdisciplinary training program for more than 30 PhD students and postdocs at the University of Würzburg.
