A great work mainly accomplished by Dr. Mathilde Courtes during her Ph.D. thesis, to who we wish the best for her postdoctoral journey with @nitikataneja.bsky.social

- Checkpoint signaling slows down replication in response to Top1 poisoning by camptothecin. - Checkpoint signaling is actively dampened by Slx4 and Fun30 to permit Exo1-dependent resection of replication forks. - Checkpoint dampening is critical to promote replication fork protection and preserve genome stability.

Today we are very pleased to share our latest article available now online @narjournal.bsky.social about the role of Slx4 scaffold and Fun30 (SMARCAD1 homolog) in DNA damage response regulation and replication fork protection against Top1-DNA crosslinks. academic.oup.com/nar/article/...

Most human DNA replication initiation is dispersed throughout the genome with only a minority within previously identified initiation zones - Genome Biology Background The identification of sites of DNA replication initiation in mammalian cells has been challenging. Here, we present unbiased detection of replication initiation events in human cells using ...

PLAMseq enables the proteo-genomic characterization of chromatin-associated proteins and protein interactions in a single experimental workflow. Chromatin Immunoprecipitation (ChIP) and Co-Immunoprecipitation (CoIP) assays are the most common approaches to characterize the genomic localization and protein interactors, respectively, for a prote...

New preprint from the Lab at @cabimer.bsky.social. We present PLAMseq, using TurboID to do like ChIPseq and proximity proteomics in the same protocol with extra powers like mapping protein interactions in the genome.

An ATM-PPM1D Circuit Controls the Processing and Restart of DNA Replication Forks In response to DNA replication stress, DNA damage signaling kinases inhibit origin firing and promote the remodeling and stabilization of replication forks, leading to a systemic reduction in DNA synt...

New preprint from the lab:

ATM controls fork processing and restart, and the PPM1D phosphatase is needed to properly balance this action of ATM.

G-quadruplex–stalled eukaryotic replisome structure reveals helical inchworm DNA translocation DNA G-quadruplexes (G4s) are non–B-form DNA secondary structures that threaten genome stability by impeding DNA replication. To elucidate how G4s induce replication fork arrest, we characterized fork ...

How do replisomes walk on DNA?

Neutral Lipids restrict DNA mobility!!
1. This has important implications for DNA repair in vivo,
2. also in vitro when you measure DNA breaks using the comet assay, beware!
3. And, we provide a fast new protocol overcoming this issue 😍

Profiling Tel1 Signaling Reveals a Non-Canonical Motif Targeting DNA Repair and Telomere Control Machineries The stability of the genome relies on Phosphatidyl Inositol 3-Kinase-related Kinases (PIKKs) that sense DNA damage and trigger elaborate downstream si…

In this new paper we find that Tel1 kinase (yeast ATM) targets D/E-S/T motifs… more prevalent than S/T-Q!

Mec1 (yeast ATR) can’t target D/E-S/T, so we think D/E-S/T targeting allows Tel1 functional specialization.

A mutation in Tel1 makes it only target S/T-Q… and cells become CPT sensitive.

PNKP safeguards stalled replication forks from nuclease-dependent degradation during replication stress Mashayekhi et al. demonstrate that polynucleotide kinase-phosphatase (PNKP) protects stalled replication forks from excessive degradation by preventing the accumulation of DNA ends with incompatible termini. Loss of PNKP leads to nascent DNA degradation via EXO1 exonuclease activity, independently of the BRCA2 pathway.

HU traps Top1 on stalled replication forks! Important to consider when inducing replication stress with HU. In addiction to HU-induced oxidative stress!
