Genome Integrity

The Department of Genome Integrity, headed by Drs Bertrand LLorente and Pierre-Henri Gaillard, investigates the fundamental mechanisms that maintain genome stability through DNA replication, repair and recombination, and how their disruption contributes to cancer development.

With a solid foundation in basic research, the department also builds translational programmes to advance oncology. Its six research teams combine a variety of biological models and scientific approaches to support a continuum from basic discoveries to potential clinical applications.

The department is also strongly committed to training the next generation of scientists in state-of-the-art techniques with an overarching mission to deepen our understanding of genome maintenance mechanisms and their implications for cancer biology and treatment.

CDK1 phosphorylation switches SLX4 SAP from DNA binding to MUS81 binding
Scaglione and Gaillard show that the SLX4 SAP domain selectively binds four-way branched DNA structures. Their findings identify CDK1 phosphorylation as a molecular switch that inhibits DNA binding while promoting MUS81 interaction, thereby temporally controlling distinct SAP functions.
