Really cool new cryoEM structure of RAD51 caught in the act of recombination initiation at a D-loop. elifesciences.org/reviewed-pre...

πŸ’₯πŸ›ŸWow cyclic peptides are cool! So excited to share a new publication on "Potent Cyclic Peptide Inhibitors Disrupt the FANCM–RMI Interaction". Work led by @yuhenglau.bsky.social to which we contributed structures and ideas. The top hits mimic native MM2...but in reverse! pubs.acs.org/doi/10.1021/...

BRCA2 C-terminal clamp restructures RAD51 dimers to bind B-DNA for replication fork stability: Molecular Cell www.cell.com/molecular-ce...

Andrew Deans @genomestability.bsky.social and collaborators show that #FANCM helicase has evolved from an ancient repair motor into a specialized sensor coupling DNA-damage recognition to Fanconi Anemia pathway activation www.embopress.org/doi/full/10....

🧬 New from crystal structures from our lab in EMBO Journal! We reveal how the FANCM enzyme, an emerging therapeutic target it cancer, has evolved to specifically recognise branched DNA and activate the Fanconi anaemia pathway of DNA repair. doi.org/10.1038/s443... πŸ§΅πŸ‘‡

CST complex blocks end resection by BLM-DNA2 or EXO1, therefore promoting non-homologous endjoining and inhibiting repair templated DNA repair. www.science.org/doi/10.1126/...

Due to great enthusiasm, we are extending the early bird registration deadline, at a reduced rate, until 25 May. After this date, the rate will increase by 1500NOK (approx. 135USD). We look forward to seeing you in Trondheim! www.endodnadamage.com

NHMRC has decided to replace the standard scale of 1-7 with something a bit more nuanced for the next round of Investigator grants. Score descriptors to be released soon.

I'm super excited to announce that registrations are now open for the 19th Australian Cell Cycle, DNA Repair and Telomere Workshop. Awesome international speaker line-up, with plenty of locals being invited! Book now to secure your earlybird rate. www.australiancellcycle.org

Some seriously nice biochemistry and cryo-EM of FAN1-PCNA-flapDNA complexes! www.nature.com/articles/s41...

Excited to share our latest from my postdoc at @mskcancercenter.bsky.social in the Sfeir Lab, in collaboration with the Simon Powell Lab! We uncovered a novel genome repair mechanism in human cells: RNA-templated DNA double-strand break repair (RT-DSBR). (1/5)

What governs where DNA replication begins in human cells? Here, we show that origins of replication in human DNA are epigenetically specified and that crucially, this epigenetic mark is required for both DNA replication and cell proliferation! @narjournal.bsky.social academic.oup.com/nar/article/...

Excited to see this out in @science.org today!! www.science.org/doi/10.1126/...

🚨 new preprint from the lab. Combining modeling, new Hi-C data in yeast and data analysis, our study offers new insights into the spatial and dynamic organization of chromatin during replication in eukaryotes. Check the tweetorial below ⬇️ www.biorxiv.org/content/10.1...

🧬 New research discovers sequential phosphorylation of MRE11 by ATM and ATR prevents extensive DNA degradation at stalled replication forks www.pnas.org/doi/abs/10.1...

FANCX=FAAP100, new Fanconi Anemia gene Two new papers identify 3 families with FAAP100 homozygous mutations leading to severe developmental and hematologic abnormalities leading to death in utero or in early life. www.jci.org/articles/vie... www.jci.org/articles/vie...

Super cool new preprint: FANCD2:FANCI is a sensor of open chromatin, independent of DNA damage, but further increased at double strand breaks. www.biorxiv.org/content/10.1...

Today, we report that APOBEC3B targets unprotected single-stranded DNA at replication forks upon ATR inhibition, triggering a reaction cascade involving UNG2 and APE1 that leads to fork collapse and hyperactivation of PARP1, causing replication catastrophe. www.science.org/doi/10.1126/...

So excited to share our new paper out today in @nature.com. We repurposed R2 retrotransposons to create STITCHR, a tool that can make virtually any kind of edit in mammalian genomes including the scarless multi-kilobase scale insertions 🧡 www.nature.com/articles/s41...

Join us at the unique conference in the field on DNA and RNA - the 8th EU-US Conference on Endogenous Damage and Repair in Norway, Trondheim, 5th-8th October! www.endodnadamage.com Secure your spot, only 26 days til the early-bird deadline! Several spaces for oral presentations available. Pls share

I ❀️ this new paper on RAD52 at replication forks, just published @nature.com. Cryo-EM reveals a unique double-ring structure that blocks reversal of replication forks. www.nature.com/articles/s41...

Striking new study from @archaeon-alex.bsky.social's lab just out in @science.org on multicellular development induced by compression in Archaea: www.science.org/doi/10.1126/...

I heard that some scientists have secret stashes of DE81 paper, since it is no longer made by GE for DNA binding experiments. Well, your days of hoarding are over! You can now buy DE81 (and P81) from a new Australian manufacturer for a very reasonable price! www.svi.edu.au/research/pla...

Check out our review on DNA end resection! With Raphael Ceccaldi, www.nature.com/articles/s41...

πŸš€ New Paper Alert! Our latest @natrevmcb.bsky.social explores how nuclear and genome organization drive DNA double-strand break repair! 🧬 πŸ“– Free access: rdcu.be/edViW Please πŸ”„ ❀️

Happy to share our new collaboration paper in Cell Reports. We show that translation synthesis in cancer cells occurs predominantly behind the replication fork, to fill ssDNA gaps, rather than to restart stalled replication forks β€œon the fly”. www.sciencedirect.com/science/arti...

We are delighted to share our latest work, characterising the role of BRCA2 and its binding partner PALB2 at centromeres, just out in the latest issue of Cell Reports. ⬇️ www.cell.com/cell-reports...

Transcription termination sites, particularly at 5'-CCTTTTTT transcription-terminator-like sequences, are hotspots for DNA damage, independent of R-loops or replication conflicts. This represents a fourth mechanism of transcription-associated genomic instability. www.nature.com/articles/s41...

Beautiful work showing how DSBs trigger de novo cohesin loops, positioned perfectly at break sites. RAD51 spreads ~Mb within TAD limits & loop extrusion actively drives homology search - distant HR repair drops when you kill cohesin loading by NIPBL! #DNArepair www.biorxiv.org/content/10.1...

New #preprint from the lab! Do you want to see the invisible? So did we! When DNA genomes get broken, cells somehow find related sequences to fix the break. But how do they find it? We developed a way to look at sequence *search*, not just sequence usage. doi.org/10.1101/2025...

Excited to present Social DNAing tomorrow. I’ll talk about our work led by @szmyd-radoslaw.bsky.social in collaboration with @radoncdocgee.bsky.social. 12 pm Eastern USA Thanks Shan Zha for the invite. www.cancer.columbia.edu/research/pro...
