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...

MetabolomicsATAD3A has a scaffolding role regulating mitochondria inner membrane structure and protein assembly

The ATPase Family AAA Domain Containing 3A (ATAD3A), is a mitochondrial inner membrane protein conserved in metazoans. ATAD3A has been associated with several mitochondrial functions, including nucleoid organization, cholesterol metabolism, and mitochondrial translation. To address its primary ro...

MetabolomicsNew plasma preparation approach to enrich metabolome coverage in untargeted metabolomics: plasma protein bound hydrophobic metabolite release with proteinase K
Plasma untargeted metabolomics is a common method for evaluation of the mechanisms underlying human pathologies and identification of novel biomarkers. The plasma proteins provide the environment for transport of hydrophobic metabolites. The current sample preparation protocol relies on the immediat...

MetabolomicsTargeted degradation of the α-ketoglutarate dehydrogenase mediated by a mitochondrial DNAJC protein regulates metabolism

Mitochondrial heat shock proteins and co-chaperones play essential roles in maintaining proteostasis. They are renowned for regulating unfolded proteins, usually without specific target preferences. In this study, we identified T cell activation inhibitor, mitochondria (TCAIM), as a novel DNAJC-t...

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...

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...

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...
