The mitochondrial unfolded protein response in mammalian physiology

Johan Auwerx, Adrienne Joëlle Laurence Mottis, Virginija Jovaisaite

Mitochondria, the main site of cellular energy harvesting, are derived from proteobacteria that evolved within our cells in endosymbiosis. Mitochondria retained vestiges of their proteobacterial genome, the circular mitochondrial DNA, which encodes 13 subu ...

Functional Characterization of the Mouse Olfactory Receptor mOR256-17 in Live Cells

Thamani Dahoun

Olfactory receptors (ORs) constitute the largest family of sensory membrane proteins in mammals. They play a key role within the olfactory system to recognize and discriminate a nearly unlimited number of structurally diverse odorant molecules. The molecul ...

Structure of active dimeric human telomerase

Joachim Lingner

Telomerase contains a large RNA subunit, TER, and a protein catalytic subunit, TERT. Whether telomerase functions as a monomer or dimer has been a matter of debate. Here we report biochemical and labeling data that show that in vivo-assembled human telomer ...

Histone H3 K27 trimethylation inhibits H3 binding and function of SET1-like H3K4 methyltransferase complexes

Beat Fierz, Zhipeng Tang

Trimethylated histone H3 lysine 4 (H3K4) and H3K27 generally mark transcriptionally active and repressive chromatins, respectively. In most cell types, these two modifications are mutually exclusive and this segregation is crucial for the regulation of gen ...

Macromolecular Symmetric Assembly Prediction Using Swarm Intelligence Dynamic Modeling

Matteo Dal Peraro, Matteo Thomas Degiacomi

Proteins often assemble in multimeric complexes to perform a specific biologic function. However, trapping these high-order conformations is difficult experimentally. Therefore, predicting how proteins assemble using in silico techniques can be of great he ...

Transforming terpene feedstock into polyketide architecture

Christoph Heinz

The Cu-catalyzed synthesis of skipped 1,4-dienes from allylic acetates and vinyl-Grignard reagents is key to bidirectional modifications of acyclic terpene acetates. As a result, trisubstituted double bond containing subunits can be readily transferred int ...

Investigation of Integrin Expression in Human Mesenchymal Stem Cells during Chondrogenesis in Different Culture Systems

Amanda Verpoorte

Cartilage tissue engineering aims to develop a material that can be implanted with cells to repair damage in articular cartilage. The extracellular matrix is known to play a key role in regulating stem cell behaviour via cell-matrix interactions and integr ...

Polarity mediates asymmetric trafficking of the G beta heterotrimeric G-protein subunit GPB-1 in C. elegans embryos

Pierre Gönczy, Kalyani Thyagarajan

Asymmetric cell division is an evolutionarily conserved process that gives rise to daughter cells with different fates. In one-cell stage C. elegans embryos, this process is accompanied by asymmetric spindle positioning, which is regulated by anterior-post ...

Gamma-Secretase Dependent Gene Expression

Alexandra Marie-Isabelle Karoline Brigitte Magold

The causes of sporadic Alzheimer's Disease (AD), the most common form of dementia at old age, are still unknown. Familial early onset AD (FAD) is mainly caused by mutations of Presenilins (PS), the active subunits of γ-secretase. Processing of its substrat ...

Atypical DNA recognition mechanism used by the EspR virulence regulator of Mycobacterium tuberculosis

Stewart Cole, Giovanni Dietler, Matteo Dal Peraro, Florence Pojer, Marco Stenta, Livan Bladimir Alonso Sarduy, Benjamin Blasco

The human pathogen Mycobacterium tuberculosis requires the ESX-1 secretion system for full virulence. EspR plays a key role in ESX-1 regulation via direct binding and transcriptional activation of the espACD operon. Here, we describe the crystal structures ...
