In a new paper, Rashid & Roy characterize a novel RNA-binding helicase, HZL-1. The protein regulates reproductive developmental quiescence in C. elegans through inhibition of key mRNAs, and sits on the axis between conserved AMPK & TOR metabolic signaling pathways. journals.plos.org/plosbiology/...

Thrilled to share our latest work - now available in full in Nature Communications - led in my lab by @vcherdy.bsky.social, with key collaborative contributions from @nitikataneja.bsky.social . rdcu.be/eVrxX

McGill is recruiting top-tier researchers working abroad through the federally funded Canada Impact+ Research Chairs program, addressing global and national challenges. The first round is due in early 2026. Learn more and submit your candidacy: https://mcgill.ca/x/5Zh

Ever wondered how TIMELESS/TIPIN can sit at the leading edge of the replication fork regulating its speed, but also bind polymerases and ssDNA/RPA in replication stress? We have an idea how it might work! Check out our new preprint, any feedback is highly appreciated! www.biorxiv.org/content/10.6...

replicationists & recombinatics take note 👇 cells deal with transcription-replication collisions (TRCs) much more professionally and efficiently than the best bridge engineers. OK, they've had more time to practice... thx, zeynep for pointing this out 🙏 #MicroSky

academic.oup.com/nar/article/... Collaboration with Y. Yamaichi. Killing donor bacteria in conjugation mixes using water enables transcriptomic profiling of early plasmid genes ! Superb tool for studying zygotic induction of these early genes, which include anti-SOS and anti-RM factors. #microsky

Our @costerlab.bsky.social review is out! It’s a great read on the impact of DNA secondary structures on eukaryotic replication fork progression - a totally unbiased opinion, of course! www.sciencedirect.com/science/arti... @adityasethi.bsky.social @billiedelpino.bsky.social

The bacterial #SOSresponse unfolds in a defined temporal order, but how does this arise? @adityakamat.bsky.social @anjbadri.bsky.social &co show that intrinsic #promoter strength, modulated by #SigmaFactor usage, governs timing of SOS gene activation in Caulobacter @plosbiology.org 🧪 plos.io/4oAKf0Q

Thrilled to share that my postdoc research is published today in @science.org! We found that DNA repair uses cohesin complexes to build new chromatin loops that guide the homology search and boost accurate repair! 1/n www.science.org/doi/10.1126/...

Our preprint is now published in PNAS! This came together thanks to a great collaboration with Antoine Hocher and a strong team effort from the Le Lab. Thank you to the reviewers and to everyone who helped improve it. I hope ParB aficionados will enjoy it. www.pnas.org/doi/10.1073/...

Cool work from Heath Murray's lab where they use Cas9 nickase to study how ssDNA breaks are repaired in Bacillus subtilis #MicroSky www.nature.com/articles/s41...

Congrats to Viri, who successfully defended her PhD thesis yesterday. Well done Dr. Lopez Jauregui! 🎉🎉💯

We are recruiting a postdoctoral fellow to study mechanisms of DNA replication stress using single-molecule imaging tools. If you are excited about microscopy, replisome dynamics, and genome stability, we’d love to hear from you. Application deadline: 24 December www.crick.ac.uk/careers-stud...

Happy to share our most recent work www.pnas.org/doi/10.1073/.... Here we describe how efficient DNA replication in E. coli is dependent on an interaction between SSB-ssDNA and the DNA polymerase (Pol III). Thanks to all the co-authors for their hard work!

📢 Excited to share that our study has just been published in Nature Communications! We uncover how CRL4-DCAF12 regulates the cellular levels of MCMBP, a chaperone essential for assembling nascent MCM2-7 complexes, to ensure accurate and error-free genome duplication.

A new, nerdy paper. We figured out (some) of the rules underlying cell-permeability of probes and designed ligands that light up, grab, and move proteins around. Awesome @hhmijanelia.bsky.social x @uwmadison.bsky.social x @stjuderesearch.bsky.social collaboration! www.pnas.org/doi/10.1073/...

Glad to share our paper out today @NatureEcoEvo: “Serial innovations by Asgard archaea shaped the DNA replication machinery of the early eukaryotic ancestor”. www.nature.com/articles/s41... #microsky #archaeasky

Hello! The Jacobs-Wagner lab is finally on Bluesky. We’re excited to celebrate science (and scientists!), share our research, and interact with the community. We look forward to connecting with friends and colleagues across the world.

This was a fun collaboration between Ophélie & the @seegerlab.bsky.social using sybody libraries to target the SMC complex in living bacteria. With a suprising finding: the 14 isolated sybodies bind to the middle of the SMC coiled coil rather than the more conserved ATPase heads.

Now in @mdpiopenaccess.bsky.social Bacillus subtilis DinG/XPD-like paralogues, DinG and YpvA, have been implicated in overcoming replication stress. DinG possesses a DEDD exonuclease and DNA helicase domains, whereas YpvA lacks the DEDD exonuclease domain www.mdpi.com/1422-0067/26...

Excited to share another study from my lab @fordhamchem now out @narjournal.bsky.social‬: doi.org/10.1093/nar/.... Most bacterial DNA polymerases must interact with the sliding clamp DnaN for their function, but we show that it’s more complicated in B. subtilis DNA replication. (1/4)
