Genetic heterogeneity in Cornelia de Lange syndrome (CdLS) and CdLS-like phenotypes with observed and predicted levels of mosaicism [PDF]

open access: yes, 2014
Cornelia de Lange syndrome (CdLS) is a multisystem disorder with distinctive facial appearance, intellectual disability and growth failure as prominent features.

Molecular basis for SMC rod formation and its dissolution upon DNA binding. [PDF]

open access: yes, 2015
SMC condensin complexes are central modulators of chromosome superstructure in all branches of life. Their SMC subunits form a long intramolecular coiled coil, which connects a constitutive "hinge" dimerization domain with an ATP-regulated "head ...

It’s all in the numbers: Cohesin stoichiometry

open access: yesFrontiers in Molecular Biosciences, 2022
Cohesin, a structural maintenance of chromosome (SMC) complex, organizes chromatin into three-dimensional structures by threading chromatin into loops and stabilizing long-range chromatin interactions. Four subunits in a 1:1:1:1 ratio compose the cohesin

Smc5/6 coordinates formation and resolution of joint molecules with chromosome morphology to ensure meiotic divisions [PDF]

open access: yes, 2013
During meiosis, Structural Maintenance of Chromosome (SMC) complexes underpin two fundamental features of meiosis: homologous recombination and chromosome segregation.

Nuclear Import and Export Signals of Human Cohesins SA1/STAG1 and SA2/STAG2 Expressed in Saccharomyces cerevisiae [PDF]

open access: yes, 2012
Background: Human SA/STAG proteins, homologues of the yeast Irr1/Scc3 cohesin, are the least studied constituents of the sister chromatid cohesion complex crucial for proper chromosome segregation.

Single-Molecule Imaging Reveals a Collapsed Conformational State for DNA-Bound Cohesin

open access: yesCell Reports, 2016
Cohesin is essential for the hierarchical organization of the eukaryotic genome and plays key roles in many aspects of chromosome biology. The conformation of cohesin bound to DNA remains poorly defined, leaving crucial gaps in our understanding of how ...

How does cohesin organize the 3D genome? [PDF]

open access: yes, 2022
Cohesin and CCCTC-binding factor (CTCF) are key regulatory proteins of three-dimensional (3D) genome organization. I will present direct evidence that cohesin extrudes DNA loops that are anchored by CTCF proteins in specific orientations.

Sensitivity of cohesin–chromatin association to high-salt treatment corroborates non-topological mode of loop extrusion

open access: yesEpigenetics & Chromatin, 2021
Cohesin is a key organizer of chromatin folding in eukaryotic cells. The two main activities of this ring-shaped protein complex are the maintenance of sister chromatid cohesion and the establishment of long-range DNA–DNA interactions through the process

Characteristics of Cohesin Mutation in Acute Myeloid Leukemia and Its Clinical Significance

open access: yesFrontiers in Oncology, 2021
The occurrence of gene mutation is a major contributor to the initiation and propagation of acute myeloid leukemia (AML). Accumulating evidence suggests that genes encoding cohesin subunits have a high prevalence of mutations in AML, especially in the t ...

Chromatin insulators and cohesins [PDF]

open access: yesThe EMBO Reports, 2008
Chromatin insulators have evolved to regulate transcription by using regulatory elements that are often distant from each other on the linear genome. This feature is position‐dependent—that is, a functional insulator must be positioned between the enhancer and its target promoter (Wallace & Felsenfeld, 2007).
