The SUMO pathway mainly functions to repress innate immunity in myeloid cells. Inactivating sumoylation triggers a strong, noncanonical, type I interferon (IFN1) response, amplified and coupled with inflammation upon stimulation. These findings transposed to pre-clinical models with the demonstratio...

Meiosis, a reductional cell division, relies on precise initiation, maturation and resolution of crossovers (COs)-connections between homologs chromosomes-to ensure their accurate segregation during metaphase I. This process is finely regulated in eukaryotes by the interplay of RING-E3 ligases such ...

By covalently linking Watson and Crick strands, DNA interstrand crosslinks (ICLs) are highly toxic lesions that block DNA replication and threaten genome integrity. The Fanconi anemia (FA) pathway orchestrates ICL repair during DNA replication, with ubiquitylated FANCI-FANCD2 (ID2) marking the activ...

DNA-protein crosslinks (DPCs) obstruct essential DNA transactions, posing a serious threat to genome stability and functionality. DPCs are proteolytically processed in a ubiquitin- and DNA replication-dependent manner by SPRTN or the proteasome but can also be resolved via targeted SUMOylation. Howe...

Lesions on DNA can uncouple DNA synthesis from helicase unwinding, generating stretches of unreplicated single stranded DNA (ssDNA) behind the replication fork. These ssDNA gaps need to be filled in to complete DNA duplication and thereby avoid the generation of DNA double-stranded breaks (DSBs), a ...
