(Submitter supplied) The precise regulation of neural stem cell quiescence and activation is crucial for normal brain development and lifelong neurogenesis. However, the mechanisms that control neural stem cell activation remains poorly understood. In this study, we investigate the role of Rad21 in this process.

(Submitter supplied) Mammalian genomes are organized into compartments, topologically-associating domains (TADs) and loops to facilitate gene regulation and other chromosomal functions. Compartments are formed by nucleosomal interactions, but how TADs and loops are generated is unknown. It has been proposed that cohesin forms these structures by extruding loops until it encounters CTCF, but direct evidence for this hypothesis is missing. more...

(Submitter supplied) Paternal genomes are compacted during spermiogenesis and de-compacted following fertilization. These processes are fundamental for inheritance but incompletely understood. We analyzed these processes in the frog Xenopus laevis, whose sperm can be assembled into functional pronuclei in egg extracts in vitro. In such extracts, cohesin extrudes DNA into loops, but in vivo cohesin only assembles topologically-associating domains (TADs) at the mid-blastula transition (MBT). more...

(Submitter supplied) We have measured absolute copy numbers and dynamics of cohesin, CTCF and their regulators NIPBL, WAPL and sororin by mass spectrometry, fluorescence-correlation spectroscopy and fluorescence recovery after photobleaching in HeLa cells before and after DNA replication. Comparison of these numbers with chromatin immunoprecipitation-sequencing data implies that some genomic cohesin and CTCF enrichment sites are unoccupied in single cells at any one time.

(Submitter supplied) This SuperSeries is composed of the SubSeries listed below, and presents the high throuput sequencing datasets that were generated as part of a larger study that investigates the role of CTCF and cohesin as key drivers of 3D-nuclear organization, anchoring the megabase-scale Topologically Associating Domains (TADs) that segment the genome. This study presents and validates a computational method to predict cohesin-and-CTCF binding sites that form intra-TAD DNA loops. more...

Our findings reveal that CTCF-based subTAD loops maintain key insulating properties of TADs, and support the proposal that subTADs are formed by the same loop extrusion mechanism and contribute to nuclear architecture as intra-TAD scaffolds that further constrain enhancer-promoter interactions. more...

(Submitter supplied) To understand how chromatin domains coordinate gene expression, we dissected select genetic elements organizing topology and transcription around the Prdm14 super enhancer in mouse embryonic stem cells. Taking advantage of allelic polymorphisms, we developed methods to sensitively analyze changes in chromatin topology, gene expression, and protein recruitment. We show that enhancer insulation does not strictly rely on loop formation between its flanking boundaries, that the enhancer activates the Slco5a1 gene beyond its prominent domain boundary, and that it recruits cohesin for loop extrusion. more...

(Submitter supplied) The large antigen receptor (AgR) loci in T and B lymphocytes have many bound CTCF sites, most of which are only occupied in lymphocytes, while only the CTCF sites at the far end of each locus near enhancers or J genes tend to be bound in non-lymphoid cells also. However, despite the generalized lymphocyte restriction of CTCF binding in AgR loci, the Igκ locus is the only locus which also shows significant lineage-specificity (T vs. more...

(Submitter supplied) The human genome folds to create thousands of loops connecting sites that are bound by the insulator protein CTCF and the ring-shaped cohesin complex. It is thought that most of these loops emerge through a process whereby cohesin extrudes chromatin, forming an initially small loop that grows larger and larger until the loop’s expansion is arrested by CTCF. Cohesin rings comprise four proteins: SMC1, SMC3, SCC1, and, in higher eukaryotes, either STAG1 or STAG2. more...

(Submitter supplied) Cohesin complex, a main organizer of mammalian genomes, exists in two versions that differ in the identity of the STAG/SA subunit, which can be SA1 or SA2. Mouse embryonic stem cell (mESC) provide a useful system to address the specific contributions of each variant to genome architecture and gene expression, since 3D organization of super- enhancers and Polycomb domains is essential to achieve transcription of pluripotency factors and repression of lineage specification genes, respectively. more...

(Submitter supplied) The DNA-binding protein CTCF and the cohesin complex function together to shape chromatin architecture in mammalian cells, but the molecular details of this process remain unclear. We demonstrate that a 79 amino acid region within the CTCF N-terminal domain but not the C-terminus is necessary for cohesin positioning at CTCF binding sites and chromatin loop formation. However, the N-terminus of CTCF, when fused to artificial zinc fingers that do not bind to CTCF DNA binding sites was not sufficient to redirect cohesin to different genomic locations, indicating that cohesin positioning by CTCF does not involve direct protein-protein interactions with cohesin subunits. more...
