Research laboratory DNA double-strand breaks (DSB) are among the most lethal forms of DNA damage.

DSBs are induced by a large number of endogenous and exogenous agents, as genotoxic chemicals and ionizing radiation, or due to replication of damaged DNA as well as collapse of a replication fork. DSB can either be properly repaired, restoring genomic integrity, or miss-repaired resulting in cell death, genomic instability, and cancer. Our group focuses on mechanisms of DSB repair using multi-disciplinary approach (biochemical, structural, computational, genetic, and single-molecule).

Off-pore Nup98 condensates mobilize heterochromatic breaks and exclude Rad51 09/06/2025

Happy to see our newest collaborative manuscript published in Mol Cell! We hope this work will substantiate the role of biomolecular condensates in the regulation of DNA repair and chromatin organization.

Off-pore Nup98 condensates mobilize heterochromatic breaks and exclude Rad51 Merigliano et al. identified a non-canonical, “off-pore” role for nucleoporins in genome stability and in the spatial regulation of homologous recombination in multicellular eukaryotes. Nup98 condensates form at DNA breaks within pericentromeric heterochromatin to prevent aberrant recombination ...

We are grateful to have received a 3-year research grant from the Czech Science Foundation, in collaboration with Karel Kubíček, to study the structure and biological role of the RAD51 protein. 🤩
