Jörg Mansfeld – Proteolysis in Cell Cycle and Cell Fate Decisions

2004-2008: PhD in Biology, Institute of Biochemistry, ETH-Zurich, Zurich, Switzerland.

2008-2012: Postdoctoral fellow at the Gurdon Institute/Cancer Research UK, Cambridge University, Cambridge, UK.

The coordination of proliferation with quiescence and differentiation is fundamental for multicellular life and development. The decision on whether cells keep dividing, or whether they temporally or permanently exit from the cell cycle is tightly controlled by ubiquitin-mediated proteolysis. Ubiquitin-mediated proteolysis requires the sequential interplay of three enzymes E1, E2, and ubiquitin E3 ligases. E3 ligases recognise and covalently modify crucial substrates such cell cycle regulators with chains of ubiquitin molecules and thereby target them for degradation by the 26S proteasome. Emerging evidence indicates that mutations in components of the ubiquitin proteasome system are a hallmark of multiple cancers and in addition interfere with faithful development and differentiation.

Our lab combines cell biological and biochemical approaches to reveal how the ubiquitin system controls cell cycle progression and the exit into quiescence and differentiation using human cells a model. For more information on our research please visit our lab page.

Open Positions

We are always looking for excellent and enthusiastic people. Please send your CV and why you want to join the lab.

We currently seek a highly motivated Postdoc with experience in redox biology and ideally an affinity for programming (i.e. via MATLAB, Mathematica or Python for single cell analyses).

Prospective PhD students are encouraged to apply through the International Max Planck Research School for Cell, Developmental and Systems Biology in cooperation with the Dresden International Graduate School for Biomedicine and Bioengineering. Informal inquiries are welcome.

We are currently looking for enthusiastic people with a background in bioinformatics especially in Python and R but do not mind to get their hands wet, for two projects that heavily rely on live cell imaging and single cell analyses.


CellTracking is a software to simplify fluorescence quantification in single cells during time-lapse microscopy. The standard procedure (definition of cell limits -segmentation-/tracking/cell cycle phases tagging/fluorescence export/alignment of multiple tracks) is partially automated. CellTracking is multiplatform, free, open source and can be downloaded here.CellTracking
