H2BK120ub and its reader RNF169 sequentially regulate replication fork remodeling and stability [PDF]
Ubiquitination of the C-terminus of histone H2B (H2BK120ub) is a key histone modification with functions in a wide array of DNA-related processes, best characterized in gene transcription and repair.

A new role for Rrm3 in repair of replication-born DNA breakage by sister chromatid recombination. [PDF]
Replication forks stall at different DNA obstacles such as those originated by transcription. Fork stalling can lead to DNA double-strand breaks (DSBs) that will be preferentially repaired by homologous recombination when the sister chromatid is ...

Automated mapping of DNA replication fork progression in human cells with ForkML [PDF]
Current approaches to mapping fork progression in the human genome suffer from drastically low throughput. Here, we introduce ForkML, a nanopore sequencing-based method automatically positioning thousands of individual fork velocities by tracking BrdU ...

An additional replication origin causes cell cycle specific DNA replication fork speed [PDF]
Replication fork speed (RFS) in Escherichia coli has long been considered constant throughout the replication and cell cycles. In wild-type cells, the circular chromosome is duplicated bidirectionally from oriC, yielding two replication forks that ...

The linker histone H1–BRCA1 axis is a crucial mediator of replication fork stability
The replication-dependent histones H1 interact with BRCA1 upon replication stress. Cells deficient for H1 fail to recruit BRCA1 to stalled replication forks and undergo fork resection and collapse.

Gene duplication and deletion caused by over-replication at a fork barrier
Replication fork stalling can provoke fork reversal to form a four-way DNA junction. This remodelling of the replication fork can facilitate repair, aid bypass of DNA lesions, and enable replication restart, but may also pose a risk of over-replication ...

Chl1 helicase controls replication fork progression by regulating dNTP pools
Chl1 helicase affects RPA-dependent checkpoint activation after replication fork arrest by ensuring proper dNTP levels, thereby controlling replication fork progression under stress conditions.

ruvA Mutants that resolve Holliday junctions but do not reverse replication forks [PDF]
RuvAB and RuvABC complexes catalyze branch migration and resolution of Holliday junctions (HJs) respectively. In addition to their action in the last steps of homologous recombination, they process HJs made by replication fork reversal, a reaction which ...

Restarted replication forks are error-prone and cause CAG repeat expansions and contractions.
Disease-associated trinucleotide repeats form secondary DNA structures that interfere with replication and repair. Replication has been implicated as a mechanism that can cause repeat expansions and contractions.

Telomere Replication: Solving Multiple End Replication Problems
Eukaryotic genomes are highly complex and divided into linear chromosomes that require end protection from unwarranted fusions, recombination, and degradation in order to maintain genomic stability.
