Cohesin architecture and clustering in vivo [PDF]

open access: yeseLife, 2021
Cohesin helps mediate sister chromatid cohesion, chromosome condensation, DNA repair, and transcription regulation. We exploited proximity-dependent labeling to define the in vivo interactions of cohesin domains with DNA or with other cohesin domains ...

Context-dependent regulation of IgH V(D)J recombination by cohesin-STAG1 and cohesin-STAG2 [PDF]

open access: yesNature Communications
Cohesin-mediated loop extrusion is central to IgH V(D)J recombination in early developing B cells, driving D-to-JH rearrangements and VH-to-DJH rearrangements, with the latter step regulated by the cohesin release factor WAPL.

Interplay between cohesin and TORC1 links chromosome segregation and gene expression to environmental changes [PDF]

open access: yeseLife
Cohesin is a DNA tethering complex essential for chromosome structure and function. In fission yeast, defects in the cohesin loader Mis4 result in chromosome segregation defects and dysregulated expression of genes near chromosome ends.

Genome-wide control of RNA polymerase II activity by cohesin. [PDF]

open access: yesPLoS Genetics, 2013
Cohesin is a well-known mediator of sister chromatid cohesion, but it also influences gene expression and development. These non-canonical roles of cohesin are not well understood, but are vital: gene expression and development are altered by modest ...

Chromosomal localization of cohesin is differentially regulated by WIZ, WAPL, and G9a

open access: yesBMC Genomics, 2022
Background The cohesin complex is essential for proper chromosome structure and gene expression. Defects in cohesin subunits and regulators cause changes in cohesin complex dynamics and thereby alter three-dimensional genome organization.

Contribution of variant subunits and associated factors to genome-wide distribution and dynamics of cohesin

open access: yesEpigenetics & Chromatin, 2022
Background The cohesin complex organizes the genome-forming dynamic chromatin loops that impact on all DNA-mediated processes. There are two different cohesin complexes in vertebrate somatic cells, carrying the STAG1 or STAG2 subunit, and two versions of

The CDK Pef1 and protein phosphatase 4 oppose each other for regulating cohesin binding to fission yeast chromosomes

open access: yeseLife, 2020
Cohesin has essential roles in chromosome structure, segregation and repair. Cohesin binding to chromosomes is catalyzed by the cohesin loader, Mis4 in fission yeast. How cells fine tune cohesin deposition is largely unknown.

Comprehensive multiomics analyses reveal pervasive involvement of aberrant cohesin binding in transcriptional and chromosomal disorder of cancer cells

open access: yesiScience, 2023
Summary: Chromatin organization, whose malfunction causes various diseases including cancer, is fundamentally controlled by cohesin. While cancer cells have been found with mutated or misexpressed cohesin genes, there is no comprehensive survey about the

Topological in vitro loading of the budding yeast cohesin ring onto DNA

open access: yesLife Science Alliance, 2018
The biochemical reconstitution of topological DNA binding by budding yeast cohesin yields surprises and opens opportunities to exploit experimental approaches developed in this model organism.

Evidence for cohesin sliding along budding yeast chromosomes [PDF]

open access: yesOpen Biology, 2016
The ring-shaped cohesin complex is thought to topologically hold sister chromatids together from their synthesis in S phase until chromosome segregation in mitosis.
