Sororin is an evolutionary conserved antagonist of WAPL
Cohesin mediates sister chromatid cohesion to enable chromosome segregation and DNA damage repair. To perform these functions, cohesin needs to be protected from WAPL, which otherwise releases cohesin from DNA.

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

Extrusion fountains are restricted by WAPL-dependent cohesin release and CTCF barriers. [PDF]
Interphase chromosomes are mainly shaped by loop extrusion and compartmentalisation mechanisms. However, their temporal component and cause-effect relationships remain largely unknown.

WAPL-Mediated Removal of Cohesin Protects against Segregation Errors and Aneuploidy [PDF]
SummaryThe classical X shape of mitotic human chromosomes is the consequence of two distinct waves of cohesin removal. First, during prophase and prometaphase, the bulk of cohesin is driven from chromosome arms by the cohesin antagonist WAPL.

The DNA loop release factor WAPL suppresses Epstein-Barr virus latent membrane protein expression to maintain the highly restricted latency I program. [PDF]
Epstein-Barr virus (EBV) uses latency programs to colonize the memory B-cell reservoir, and each program is associated with human malignancies. However, knowledge remains incomplete of epigenetic mechanisms that maintain the highly restricted latency I ...

Cross-platform Hi-C meta-analysis identifies functional insulators that actively block enhancer-promoter interactions [PDF]
The function of topologically associating domain (TAD) boundaries as transcriptional insulators remains a fundamental controversy in genome biology. Here, we demonstrate that bona fide Functional Insulators (FINs) should be defined dynamically by their ...

Wapl repression by Pax5 promotes V gene recombination by Igh loop extrusion [PDF]
Nuclear processes, such as V(D)J recombination, are orchestrated by the three-dimensional organization of chromosomes at multiple levels, including compartments1 and topologically associated domains (TADs)2,3 consisting of chromatin loops4.

S-phase PARylation of microprotein RSMC enhances the function of Sororin in sister chromatid cohesion [PDF]
Sororin is essential for establishing sister chromatid cohesion concurrently with DNA replication in metazoans. Although acetylation of the cohesin subunit SMC3 by ESCO1/2 is necessary for Sororin recruitment, it is by itself not sufficient.

Cohesin positions the epigenetic reader Phf2 within the genome [PDF]
Genomic DNA is assembled into chromatin by histones, and extruded into loops by cohesin. These mechanisms control important genomic functions, but whether histones and cohesin cooperate in genome regulation is poorly understood.
