Design of an artificial phage-display library based on a new scaffold improved for average stability of the randomized proteins

Scaffold-based protein libraries are designed to be both diverse and rich in functional/folded proteins. However, introducing an extended diversity while preserving stability of the initial scaffold remains a challenge. Here we developed an original approa ...

Two-dimensional crystallization of the mouse serotonin 5-HT3A receptor

Henning Paul-Julius Stahlberg, Horst Vogel, Ghérici Hassaïne

The mouse serotonin 5-HT3A receptor is a homo-pentameric ligand-gated ion channel (pLGIC) mediating fast excitatory neurotransmission in the central nervous system. The molecular mechanism of ion permeation of 5-HT3A receptors triggered by the neurotransmi ...

The Structure of the Mouse Serotonin 5-HT3 Receptor in Lipid Vesicles

Henning Paul-Julius Stahlberg, Horst Vogel, Cédric Deluz, Luigino Grasso, Ghérici Hassaïne

The function of membrane proteins is best understood if their structure in the lipid membrane is known. Here, we determined the structure of the mouse serotonin 5-HT3 receptor inserted in lipid bilayers to a resolution of 12 Å without stabilizing antibodie ...

X-ray structure of the mouse serotonin 5-HT3 receptor

Rudolf Hovius, Henning Paul-Julius Stahlberg, Horst Vogel, Cédric Deluz, Luigino Grasso, Romain Wyss, Menno Berend Tol, Ghérici Hassaïne

Neurotransmitter-gated ion channels of the Cys-loop receptor family mediate fast neurotransmission throughout the nervous system. The molecular processes of neurotransmitter binding, subsequent opening of the ion channel and ion permeation remain poorly un ...

Large scale expression and purification of the mouse 5-HT3 receptor

Horst Vogel, Cédric Deluz, Menno Berend Tol, Ghérici Hassaïne

Receptors of the Cys-loop family are central to neurotransmission and primary therapeutic targets. In order to decipher their gating and modulation mechanisms, structural data is essential. However, structural studies require large amounts of pure, functio ...

Downscaling the Analysis of Complex Transmembrane Signaling Cascades to Closed Attoliter Volumes

Rudolf Hovius, Horst Vogel, Joachim Piguet, Luigino Grasso, Romain Wyss, Michael Werner, Ghérici Hassaïne

Cellular signaling is classically investigated by measuring optical or electrical properties of single or populations of living cells. Here we show that ligand binding to cell surface receptors and subsequent activation of signaling cascades can be monitor ...

Thermal Unfolding of a Mammalian Pentameric Ligand-gated Ion Channel Proceeds at Consecutive, Distinct Steps

Henning Paul-Julius Stahlberg, Horst Vogel, Cédric Deluz, Menno Berend Tol, Ghérici Hassaïne

Pentameric ligand-gated ion channels (LGICs) play an important role in fast synaptic signal transduction. Binding of agonists to the beta-sheet-structured extracellular domain opens an ion channel in the transmembrane alpha-helical region of the LGIC. How ...
