MetabolomicsDifferent regions of synaptic vesicle membrane regulate VAMP2 conformation for the SNARE assembly
Vesicle associated membrane protein 2 (VAMP2/synaptobrevin2), a core SNARE protein residing on synaptic vesicles (SVs), forms helix bundles with syntaxin-1 and SNAP25 for the SNARE assembly. Prior to the SNARE assembly, the structure of VAMP2 is unclear. Here, by using in-cell NMR spectroscopy, we d...

GenomicsThe inactive X chromosome adopts a unique three-dimensional conformation that is dependent on Xist RNA.
3D-topology of DNA in the cell nucleus provides a level of transcription regulation beyond the sequence of the linear DNA. To study the relationship between transcriptional activity and spatial environment of a gene, we have used allele-specific 4C-technology to produce high-resolution topology maps...

GenomicsOncogene-Mediated Alterations in Chromatin Conformation
Emerging evidence suggests that chromatin adopts a non-random three-dimensional (3D) topology and that the organization of genes into structural hubs and domains affects their transcriptional status. How chromatin conformation changes in diseases such as cancer is poorly understood. Moreover, how on...

TranscriptomicsSpatial genome organization: contrasting views from chromosome conformation capture and fluorescence in situ hybridization
Though important for gene regulation most studies of genome organisation use either fluorescence in situ hybridisation (FISH) or chromosome conformation capture (3C) methods. FISH directly visualises the spatial relationship of sequences, but is usually applied to a few loci at a time. The frequency...

TranscriptomicsA comprehensive Xist interactome reveals cohesin repulsion and an RNA-directed chromosome conformation
The inactive X chromosome (Xi) serves as a model to understand gene silencing on a global scale. Here, we perform identification of direct RNA interacting proteins? (iDRiP) to isolate a comprehensive protein interactome for Xist, an RNA required for Xi silencing. We discover multiple classes of inte...

TranscriptomicsGlobal identification of yeast chromosome interactions using genome conformation capture
The objective of this study was to determine the global chromosomal interaction map for exponentially growing Saccharomyces cerevisiae cells using Genome Conformation Capture. Interactions between chromosomes were identified within a population of yeast cells growing exponentially in a semi-defined ...

TranscriptomicsClassifying leukemia types with chromatin conformation data (5C)
Background: Although genetic or epigenetic alterations have shown to affect the three-dimensional organization of genomes, the utility of chromatin conformation in the classification of human disease has never been addressed. Results: Here, we explore whether chromatin conformation can be used to cl...
