Replicative gaps in DNA damage tolerance, genome instability, and cancer therapy

Replicative single-stranded DNA gaps arise when DNA synthesis proceeds past lesions or difficult-to-replicate regions. This review delineates the pathways that generate, stabilize, and process these i...

Over five years of work has gone into our new preprint! The #cryoEM structure of a human RAD51 filament caught at the point of strand exchange 🧬 www.biorxiv.org/content/10.1...

Structural mechanism of strand exchange by the RAD51 filament.

Homologous Recombination (HR) preserves genomic stability by repairing double-strand DNA breaks and ensuring efficient DNA replication. Central to HR is the strand-exchange reaction taking place within the three-stranded synapsis wherein a RAD51 nucleoprotein filament binds to a donor DNA. Here we present the cryoEM structure of a displacement loop of human RAD51 that captures the synaptic state when the filament has become tightly bound to the donor DNA. The structure elucidates the mechanism of strand exchange by RAD51, including the filament engagement with the donor DNA, the strand invasion and pairing with the complementary sequence of the donor DNA, the capture of the non-complementary strand and the polarity of the strand-exchange reaction. Our findings provide fundamental mechanistic insights into the biochemical reaction of eukaryotic HR. ### Competing Interest Statement The authors have declared no competing interest.

Thrilled to share our lab's first preprint, led by an exceptional PhD student Gita Chhetri and with the support of wonderful collaborators, we find that replisome function is rate-limited by strand-specific PCNA dynamics. Hope you will enjoy reading. www.biorxiv.org/content/10.1... Brief teaser:

PAF15-PCNA assembly exhaustion governs lagging strand replication and replisome integrity
