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

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

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 ...

Global kinomic and phospho-proteomic analyses of the human malaria parasite Plasmodium falciparum

Claudia Demarta, Michele Graciotti

The role of protein phosphorylation in the life cycle of malaria parasites is slowly emerging. Here we combine global phospho-proteomic analysis with kinome-wide reverse genetics to assess the importance of protein phosphorylation in Plasmodium falciparum ...

Parasite Protein Kinases: At Home and Abroad

Two studies identify protein kinases of parasitic protists with roles in either their own development or the control of the behavior of their host cell. ...

Role of Aggregation in Rhodopsin Signal Transduction

Ursula Röthlisberger, Ivano Tavernelli, Marilisa Neri, Stefano Vanni

Many G protein-coupled receptors (GPCRs) are known to form dimers or even oligomers, and these aggregated states have been proposed as functional units responsible for signal transduction and G protein activation. However, the nature of their involvement h ...

Capillary electrophoresis hyphenated to inductively coupled plasma-mass spectrometry: A novel approach for the analysis of anticancer metallodrugs in human serum and plasma

Christian Hartinger, Michael Groessl

The development of metal-based chemotherapeutics lacks methods which are capable of providing early indication on the potential of new metal complexes as future anticancer drugs. Since most of these compounds are administered intravenously, serum proteins ...

Molecular variant fibrinogen fusion proteins

Jeffrey Alan Hubbell

Fibrinogen fusion proteins, methods of making, and methods of using fibrinogen fusion proteins are described. In a preferred embodiment the fibrinogen fusion protein contains a truncated Aa chain of fibrinogen. The Aa chain contains truncation site, which ...

Investigation of the neurokinin-1 receptor by fluorescence techniques

Bruno Meyer

G protein-coupled receptors (GPCR) constitute by far the largest family of transmembrane cell-surface proteins involved in signal transduction and are the most important targets for the development of novel therapeutic compounds. Many processes mediated by ...

Covalent labeling and chemical induced dimerization of fusion proteins

Susanne Kindermann

A new method was developed for the specific and covalent labeling of fusion proteins with small organic probes in vitro and in vivo. The method is based on the construction of fusion proteins of the human O6-alkylguanine-DNA alkyltransferase (hAGT) with a ...
