Our first foray into replication fork processing is now available! 🐸🧍🧬🧪 Key points:
- Uncoupling causes degradation and reversal
- Degradation occurs before and after reversal
- Replisomes are retained throughout
See model for how we think this works🙏

Happy to share our study about the role of Top2 complexes in different chromatin contexts!
We find that Top2 catalytic inhibition leads exclusively to instability of the repetitive genome which depends on Top2a. For more details of how, please read:

Our latest termination paper is online! 🐸🧬➡️⬅️🧬Key points:
- RTEL1-MCM10 is a 'backup' mechanism for when TOP2 is compromised
- MCM10 promotes RTEL1 binding/function
- RTEL1-MCM10 don't regulate topology but do act as a general stalled fork response

Researchers from the @Topo_Lab were instrumental in the development of the first new antibiotic treatment for uncomplicated urinary tract infections in more than 20 years.
Their collaborators @GSK will soon be filing for FDA approval.

Check out our latest story in @MolecularCell. Our team pairs the dTAG system with deep genomic analysis to determine the spatiotemporal role of SMARCA5 in the maintenance of chromatin structure and function.

📢 Hot off the press 📢
🧬 Ever wonder why some DNA sequences are difficult to replicate?
Using reconstituted replisomes we revealed that structure-forming repeats induce robust replication stalling and uncovered structure-specific recovery mechanisms:

Excited to share our latest paper, just published in EMBO J: embopress.org/doi/abs/10.152…
We found that topoisomerase II poisons exert different and unexpected effects on DNA replication. Congrats @sabrinadoessci1! Thanks also to our collaborators @Topo_Lab and @davidkcortez

Really excited to share the methods chapter we wrote for DNA Damage Responses as a part of Methods in Molecular Biology series. Here we describe really fun assays to monitor DNA replication termination using 🐸🥚 extracts! #gelsnotcells @Dewar_Lab link.springer.com/protocol/1…

Thrilled to announce another preprint from our lab! @LillianVCampos found that RTEL1 and MCM10 help replication forks overcome topological stress during termination. Thanks also to @BFEichman @DarrenHeintzman @TKavlashvili
