Computational modeling of the olfactory receptor Olfr73 suggests a molecular basis for low potency of olfactory receptor-activating compounds

Horst Arthur Vogel, Horst Pick, Shuguang Yuan, Thamani Dahoun, Marc Brugarolas Campillos

The mammalian olfactory system uses hundreds of specialized G-protein-coupled olfactory receptors (ORs) to discriminate a nearly unlimited number of odorants. Cognate agonists of most ORs have not yet been identified and potential non-olfactory processes m ...

Enhancing the Signaling of GPCRs via Orthosteric Ions

Horst Arthur Vogel, Shuguang Yuan

G protein-coupled receptors play essential roles in cellular processes such as neuronal signaling, vision, olfaction, tasting, and metabolism. As GPCRs are the most important drug targets, understanding their interactions with ligands is of utmost importan ...

Activation of G-protein-coupled receptors correlates with the formation of a continuous internal water pathway

Horst Arthur Vogel, Shuguang Yuan

Recent crystal structures of G-protein-coupled receptors (GPCRs) have revealed ordered internal water molecules, raising questions about the functional role of those waters for receptor activation that could not be answered by the static structures. Here, ...

The Mechanism of Ligand-Induced Activation or Inhibition of - and -Opioid Receptors

Horst Arthur Vogel, Shuguang Yuan

G-protein-coupled receptors (GPCRs) are important targets for treating severe diseases. However why certain molecules act as activators whereas others, with similar structures, block GPCR activation, is poorly understood since the same molecule can activat ...

Wiley-Blackwell2015

The Principles of Ligand Specificity on beta-2-adrenergic receptor

Shuguang Yuan

G protein-coupled receptors are recognized as one of the largest families of membrane proteins. Despite sharing a characteristic seven-transmembrane topology, G protein-coupled receptors regulate a wide range of cellular signaling pathways in response to v ...

Mechanistic Studies on the Stereoselectivity of the Serotonin 5-HT1A Receptor

Horst Arthur Vogel, Shuguang Yuan

G-protein-coupled receptors (GPCRs) are involved in a wide range of physiological processes, and they have attracted considerable attention as important targets for developing new medicines. A central and largely unresolved question in drug discovery, whic ...

The Molecular Mechanism of P2Y 1 Receptor Activation

Horst Arthur Vogel, Shuguang Yuan

Human purinergic Gprotein-coupled receptor P2Y(1) (P2Y(1)R) is activated by adenosine 5'-diphosphate (ADP) to induce platelet activation and thereby serves as an important antithrombotic drug target. Crystal structures of P2Y(1)R revealed that one ligand ( ...

Asymmetric opening of the homopentameric 5-HT3A serotonin receptor in lipid bilayers

Horst Arthur Vogel, Shuguang Yuan

Pentameric ligand-gated ion channels (pLGICs) of the Cys-loop receptor family are key players in fast signal transduction throughout the nervous system. They have been shown to be modulated by the lipid environment, however the underlying mechanism is not ...

Structure of a pathogen effector reveals the enzymatic mechanism of a novel acetyltransferase family

Shuguang Yuan

Effectors secreted by the type Ill secretion system are essential for bacterial pathogenesis. Members of the Yersinia outer-protein J (YopJ) family of effectors found in diverse plant and animal pathogens depend on a protease-like catalytic triad to acetyl ...

Using PyMOL as a platform for computational drug design

Shuguang Yuan

PyMOL, a cross-platform molecular graphics tool, has been widely used for three-dimensional (3D) visualization of proteins, nucleic acids, small molecules, electron densities, surfaces, and trajectories. It is also capable of editing molecules, ray tracing ...

Designing Safer Analgesics via mu-Opioid Receptor Pathways

Shuguang Yuan

Pain is both a major clinical and economic problem, affecting more people than diabetes, heart disease, and cancer combined. While a variety of prescribed or over-the-counter (OTC) medications are available for pain management, opioid medications, especial ...

A Gating Mechanism of the Serotonin 5-HT3 Receptor

Horst Arthur Vogel, Shuguang Yuan

Our recently solved high-resolution structure of the serotonin 5-HT3 receptor (5-HT3R) delivered the first detailed structural insights for a mammalian pentameric ligand-gated ion channel. Based on this structure, we here performed a total of 2.8-μs all-at ...

W246(6.48) Opens a Gate for a Continuous Intrinsic Water Pathway during Activation of the Adenosine A(2A) Receptor

Horst Arthur Vogel, Shuguang Yuan

The question how G-protein-coupled receptors transduce an extracellular signal by a sequence of transmembrane conformational transitions into an intracellular response remains to be solved at molecular detail. Herein, we use molecular dynamics simulations ...

Exchanging ligand-binding specificity between a pair of mouse olfactory receptor paralogs reveals odorant recognition principles

Horst Arthur Vogel, Horst Pick, Shuguang Yuan, Luc Veya, Olivia Baud

A multi-gene family of ~1000 G protein-coupled olfactory receptors (ORs) constitutes the molecular basis of mammalian olfaction. Due to the lack of structural data its remarkable capacity to detect and discriminate thousands of odorants remains poorly unde ...

The role of metal ions in G protein-coupled receptor signalling and drug discovery

Horst Arthur Vogel, Shuguang Yuan

Metal ions, such as Na+, Mg2+, Ca2+, and Zn2+, are highly abundant in biological systems. For many G protein-coupled receptors (GPCRs), metal ions, especially Na+, have been found to stabilize the receptors' inactivate state preventing receptor activation. ...
