Welcome to the Collaborative Research Centre "Molecular Mechanisms on Cell State Transitions" (CRC 1430). The CRC 1430 brings together scientist of the Center of Medical Biotechnology at the University of Duisburg-Essen, the Max Planck Institute of Molecular Physiology and the Universities of Dortmund, Münster, Cologne and Frankfurt.


The DFG-funded CRC 1430 "Molecular Mechanisms of Cell State Transitions" explores fundamental molecular mechanisms that underlie the regulation of cell proliferation. Cell proliferation needs to be tightly controlled to ensure organismal development and tissue regeneration, while preventing neoplastic disorders. A key hallmark of this control is the establishment of distinct, biochemically or epigenetically defined cell states and the regulated transitions between these states.

These transitions govern cell cycle progression and underlie cancer cell plasticity and cancer therapy resistance. The research focus is on understanding the switch-like molecular trigger mechanisms of state transitions and develop means to modulate them, ultimately to identify novel therapeutic strategies. Specifically, to overcome current limitations, the CRC 1430 will develop and apply direct methodologies such as advanced biochemical reconstitution and novel approaches of acute chemical or optical perturbation to decipher how the key triggers sense, integrate and transmit signals to regulatory circuits that define cell states.

Aug 21, 2022 Novel Web Tool PPI-Affinity

A new paper is out, published in the Journal of Proteome Research with a cover image featured in the current issue. It introduces PPI-Affinity, a web tool developed by scientists of the groups of Elsa Sánchez García and Michael Ehrmann.  The web server scores protein–protein and protein–peptide complexes based on their predicted binding affinity and also optimizes the affinity of a complex by mutating and screening selected residues. PPI-Affinity can be employed at early steps of drug design processes and thus support the design of new  therapeutics significantly.

PPI-Affinity is freely accessible at https://protdcal.zmb.uni-due.de/PPIAffinity.
