As the University of Zurich resumes on-site operations with applicable safety concepts in place also our lab resumes experimental work, albeit with reduced capacity and with safety precautions.
In our recent publication in Cell Reports we reveal that the ubiquitin E3 ligase TRIP12, through its PAR-binding WWE domain, targets PARP1 for proteasomal degradation, affecting PARP functions and PARPi efficiency.
We have openings for a postdoctoral researcher and MSc/PhD students to join our lab. If you are interested in cancer biology and genome integrity maintenance and have a liking for quantitative cell biology, please take a look.

We show that the ubiquitin E3 ligase TRIP12, through its PAR-binding WWE domain, targets PARP1 for proteasomal degradation, affecting PARP functions and PARP inhibitor efficiency. Great work with important implications worth following up. Congratulations to Marco Gatti and big thanks to our collaborators Qingyao Huang and Michael Baudis for their help. Published in Cell Reports.

The DNA damage response factor and chromatin binder 53BP1 generates repair compartments around DNA breaks. In a paper published in EMBO Journal (2019)38:e101379 we show that these nuclear compartments show liquid-like properties, exhibit induced self‐assembly based on 53BP1’s oligomerization potential, and undergo fusion and fission events with potential implications for break clustering and chromosomal translocations. 53BP1 condensates are sensitive to disruption of weak interactions, and can co-assemble and contribute to the activation of tumor suppressor protein p53.

Replication stress is a hallmark of many cancers. In an article published in the February 2019 issue of Molecular Cell (Volume 73, Issue 4, p641-858) we identify the pre-mRNA cleavage factor WDR33 as regulator of replication stress resilience and demonstrate that, when WDR33 function is impaired, unreleased nascent transcripts and genomic loci re-localize toward the nuclear periphery, where they cause replication stress and DNA damage.

Our paper on PARP inhibitor toxicity is published in Nature Communications! Have a look how high-content imaging reveals the earliest cellular responses to PARP inhibition and unravels the sequence of events from PARP trapping to DNA damage, cell cycle arrest and cell death. Here you can access the complete article and browse through the Editors’ Highlights, or read the UZH/EurekAlert public releases.
