Katrin Paeschke's research focuses on specific DNA and RNA structures named G-quadruplexes (G4s). These structures form within all living cells including virus where they support cellular functions. The Paeschke group aims to characterise how DNA and RNA G-quadruplex structures are recognised and regulated by proteins.We utilise a combination of molecular, biochemical and global experimental approaches (ChIP-seq, ATAC-seq, Cut & Tag, RNA-seq, PAR-CLIP) to better understand the molecular network and contribution of G4s for genome stability and cellular functions in living cells. We also aim to characterise how G4-protein interactions (both on DNA and RNA levels) contribute to the immune response activation and how these structures can modulate the immune response.
