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

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

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

Chromatin insulators and cohesins [PDF]
The 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).

Epigenetics & 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
Frontiers 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 ...

The torments of the cohesin ring [PDF]
Nucleus, 2017 Cohesin is a ring-shaped protein complex which comprises the Smc1, Smc3 and Scc1 subunits. It topologically embraces chromosomal DNA to connect sister chromatids and stabilize chromatin loops. It is required for proper chromosomal segregation, DNA repair and transcriptional regulation. We have recently reported that cohesin rings can adopt a "collapsed"

Histone chaperone NAP1 mediates sister chromatid resolution by counteracting protein phosphatase 2A.
PLoS Genetics, 2013 Chromosome duplication and transmission into daughter cells requires the precisely orchestrated binding and release of cohesin. We found that the Drosophila histone chaperone NAP1 is required for cohesin release and sister chromatid resolution during ...

A folded conformation of MukBEF and Cohesin [PDF]
Nature Structural & Molecular Biology, 2018 Abstract Structural maintenance of chromosomes (SMC)-kleisin complexes organize chromosomal DNAs in all domains of life, where they have key roles in chromosome segregation, DNA repair and regulation of gene expression. They function through topological entrapment and active translocation of DNA, but the underlying conformational ...
