Different NIPBL requirements of cohesin-STAG1 and cohesin-STAG2
Abstract Cohesin organizes the genome through the formation of chromatin loops. NIPBL activates cohesin’s ATPase and is essential for loop extrusion, but its requirement for cohesin loading is currently unclear. Here we have examined the effect of reducing NIPBL levels on the behavior of the two cohesin variants carrying STAG1 or STAG2 ...

RAD2lL and REC8, meiosis-specific paralogs of the canonical cohesin subunit RAD21, are essential for proper formation of axial/lateral elements of the synaptonemal complex, synapsis of homologous chromosomes, and crossover recombination in mammalian ...

Cohesins and Cohesin-Regulators in Meiosis [PDF]
Cells have rigorous mechanisms controlling sister chromatid cohesion during cell division to ensure proper distribution of genetic material to daughter cells. Errors in these mechanisms often lead to aneuploidy, frequently implicated in cell death, tumour development and infertility.

The torments of the cohesin ring [PDF]
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"

Cohesin and chromosome segregation [PDF]
Cohesin is a ring-shaped protein complex that organises the genome, enabling its condensation, expression, repair and transmission. Cohesin is best known for its role in chromosome segregation, where it provides the cohesion that is established between the two newly duplicated sister chromatids during S phase.

Cohesin and Human Disease [PDF]
Cornelia de Lange syndrome (CdLS) is a dominant multisystem disorder caused by a disruption of cohesin function. The cohesin ring complex is composed of four protein subunits and more than 25 additional proteins involved in its regulation. The discovery that this complex also has a fundamental role in long-range regulation of transcription in ...

Cohesin Mutations in Cancer [PDF]
Cohesin is a large ring-shaped protein complex, conserved from yeast to human, which participates in most DNA transactions that take place in the nucleus. It mediates sister chromatid cohesion, which is essential for chromosome segregation and homologous recombination (HR)-mediated DNA repair.

Dependency of Heterochromatin Domains on Replication Factors
Chromatin structure regulates both genome expression and dynamics in eukaryotes, where large heterochromatic regions are epigenetically silenced through the methylation of histone H3K9, histone deacetylation, and the assembly of repressive complexes ...

Pds5 promotes cohesin acetylation and stable cohesin–chromosome interaction [PDF]
Pds5 and Wpl1 act as anti-establishment factors preventing sister-chromatid cohesion until counteracted in S-phase by the cohesin acetyl-transferase Eso1. However, Pds5 is also required to maintain sister-chromatid cohesion in G2. Here, we show that Pds5 is essential for cohesin acetylation by Eso1 and ensures the maintenance of cohesion by promoting a
