Our laboratory studies the sequence-function relationship of transcription factor (TF) mediated cell fate conversions. We use structural modelling and quantitative biochemical assays to analyse the formation of TF complexes on regulatory DNA in combination with deep sequencing techniques.  By contrasting the dynamic binding and gene regulation of paralogous TFs and engineered factors we learn about ‘enhancer codes’ directing pluripotency reprogramming and identify functionally critical structural elements. Lessons learned from these studies allowed us to identify artificially evolved transcription factors that substantially outperform their wild-type counterparts. Our present aims are to decode the functional basis for the enhanced function for artificially evolved transcription factors and to develop novel methods for the directed factor evolution in mammalian cells. Our vision is that any biomolecule-driven cell fate conversion can be enhanced with synthetic factors that will enable the application of reprogramming technologies in regenerative biomedicine.
