A requirement for STAG2 in replication fork progression creates a targetable synthetic lethality in cohesin-mutant cancers. [PDF]
, 2019 Cohesin is a multiprotein ring that is responsible for cohesion of sister chromatids and formation of DNA loops to regulate gene expression. Genomic analyses have identified that the cohesin subunit STAG2 is frequently inactivated by mutations in cancer.

Sister Chromatid Cohesion Remodeling and Meiotic Recombination [PDF]
Cell Cycle, 2006 Proper control of cohesion along the chromosome arms is essential for segregation of homologous chromosomes in meiosis. In a recent study we reported that Tid1p, a protein previously implicated in recombination, is required for resolution of Mcd1p-dependent cohesion in meiosis. Here we demonstrate that Pds5p and Dmc1p promote this cohesion.

In Favor of Establishment: Regulation of Chromatid Cohesion in Plants
Frontiers in Plant Science, 2017 In eukaryotic organisms, the correct regulation of sister chromatid cohesion, whereby sister chromatids are paired and held together, is essential for accurate segregation of the sister chromatids and homologous chromosomes into daughter cells during ...

Smc5/6: a link between DNA repair and unidirectional replication? [PDF]
, 2008 Of the three structural maintenance of chromosome (SMC) complexes, two directly regulate chromosome dynamics. The third, Smc5/6, functions mainly in homologous recombination and in completing DNA replication.

Cohesin causes replicative DNA damage by trapping DNA topological stress [PDF]
, 2020 DNA topological stress inhibits DNA replication fork (RF) progression and contributes to DNA replication stress. In Saccharomyces cerevisiae, we demonstrate that centromeric DNA and the rDNA array are especially vulnerable to DNA topological stress ...

Evidence that MEK1 positively promotes interhomologue double-strand break repair [PDF]
, 2010 During meiosis there is an imperative to create sufficient crossovers for homologue segregation. This can be achieved during repair of programmed DNA double-strand breaks (DSBs), which are biased towards using a homologue rather than sister chromatid as ...

High density of REC8 constrains sister chromatid axes and prevents illegitimate synaptonemal complex formation [PDF]
, 2016 During meiosis, cohesin complexes mediate sister chromatid cohesion (SCC), synaptonemal complex (SC) assembly and synapsis. Here, using super-resolution microscopy, we imaged sister chromatid axes in mouse meiocytes that have normal ...

Modifying sister chromatid cohesion for meiosis [PDF]
Journal of Cell Science, 2004 Meiosis produces haploid gametes from diploid cells in two stages that in many ways resemble mitosis. However, the regulatory mechanisms governing kinetochore orientation and cohesion at the first meiotic division are different from those at mitosis: sister kinetochores are pulled forwards from the same spindle pole at metaphase, and centromeric ...

A Live-Cell Imaging Approach for Measuring DNA Replication Rates
Cell Reports, 2018 Summary: We describe a simple and direct approach to measure the progression of single DNA replication forks in living cells by monitoring two fluorescently labeled loci downstream of an origin of replication.
