DNA replication is an essential and one of the most complex processes in the cell. Not only exogenous DNA damage but also intrinsic DNA structures including G-quadruplexes (G4) and R-loops, their stabilization or unscheduled formation represent major replication obstacles with possible detrimental effects on genome integrity. Not surprisingly, those processes are pharmacologically targeted in anticancer therapy, despite the fact that only little is known about the underlying molecular mechanisms. It becomes apparent that maintenance of processive DNA replication requires sophisticated protein networks beyond the core replisome. Whether there is a direct crosstalk between G4 and R-loops, what proteins are involved in their homeostasis and what are the factors diversifying between their beneficial and pathological roles, is not well understood. The goals of our research are to identify proteins associated with G4 and R-loop structures and understand their roles in G4/R-loop formation and resolution as well as relationship to replication fork progression and associated repair.
