Computationally designed GPCR quaternary structures bias signaling pathway activation

Patrick Daniel Barth, Robert Everett Jefferson

Communication across membranes controls critical cellular processes and is achieved by receptors translating extracellular signals into selective cytoplasmic responses. While receptor tertiary structures can be readily characterized, receptor associations ...

The Contorsbody, an antibody format for agonism: design, structure, and function

Henning Paul-Julius Stahlberg

The careful design of the antibody architecture is becoming more and more important, especially when the purpose is agonism. We present the design of a novel antibody format that is able to promote receptor dimerization and induce signal transduction resul ...

Phosphoregulated orthogonal signal transduction in mammalian cells

Leo Scheller, Maysam Mansouri

Orthogonal tools for controlling protein function by post-translational modifications open up new possibilities for protein circuit engineering in synthetic biology. Phosphoregulation is a key mechanism of signal processing in all kingdoms of life, but too ...

Hybrid Transcriptional Regulators for the Screening of Target DNA Motifs in Organohalide-Respiring Bacteria

Christof Holliger, Julien Maillard, Mathilde Stéphanie Willemin, Marie Vingerhoets

The bioremediation of persistent organohalide molecules under anoxic conditions mostly relies on the bacterial process called organohalide respiration (OHR). Organohalide-respiring bacteria (OHRB) are phylogenetically diverse anaerobic bacteria that share ...

Revealing GPCR oligomerization at the single-molecule level through a nanoscopic lens: methods, dynamics and biological function

Aleksandra Radenovic, Paolo Annibale, Marco Scarselli

The introduction of super-resolution fluorescence microscopy has allowed the visualization of single proteins in their biological environment. Recently, these techniques have been applied to determine the organization of class A G-protein-coupled receptors ...

A New Role for Escherichia coli DsbC Protein in Protection against Oxidative Stress

Camille Véronique Bernadette Goemans

We report a new function for Escherichia coli DsbC, a protein best known for disulfide bond isomerization in the periplasm. We found that DsbC regulates the redox state of the single cysteine of the l-arabinose-binding protein AraF. This cysteine, which ca ...

Nodal.Gdf1 Heterodimers with Bound Prodomains Enable Serum-independent Nodal Signaling and Endoderm Differentiation

Daniel Constam, Christophe Fuerer

The TGF beta family member Nodal is central to control pluripotent stem cell fate, but its use as a stem cell differentiation factor is limited by low specific activity. During development, Nodal depends on growth and differentiation factor (Gdf)-1 and on ...

The Crystal Structures of Apo and cAMP-Bound GlxR from Corynebacterium glutamicum Reveal Structural and Dynamic Changes upon cAMP Binding in CRP/FNR Family Transcription Factors

Stewart Cole, Florence Pojer

The cyclic AMP-dependent transcriptional regulator GlxR from Corynebacterium glutamicum is a member of the super-family of CRP/FNR (cyclic AMP receptor protein/fumarate and nitrate reduction regulator) transcriptional regulators that play central roles in ...

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 ...

Magnetization and specific heat of the dimer system CuTe2O5

Helmuth Berger, Zheng Wang

We report on magnetization and specific heat measurements on single-crystalline CuTe2O5. The experimental data are directly compared to theoretical results for two different spin structures, namely an alternating spin-chain and a two-dimensional (2D) coupl ...
