Odorant receptors are an excellent example of natural superiority in binding specific, small and hydrophobic molecules, and therefore are of particular interest in the development of a sensor platform for G protein-coupled receptors (GPCRs). Odorant recept ...
Press-fitting is a very common assembly process used in many fields, especially in the watchmaking industry. It consists of introducing a shaft in a hole (also called receptor) with a certain value of tightening (or interference). However, this process is ...

Recently, it has been shown that correct trafficking of neuronal plasma membrane receptors along the endosomal pathway is directly implicated in molecular mechanisms underlying synaptic plasticity and is fundamental for proper neuronal communication. To un ...
G-protein coupled receptors (GPCRs) are the most abundant class of proteins in the cell body. Such receptors are of major interest as potential therapeutic targets. Downscaling and parallelization of bioanalytics opens novel routes to rapidly screen and id ...
Sequential stages in the life cycle of the ionotropic 5-HT3 receptor (5-HT3R) were resolved temporally and spatially in live cells by multicolor fluorescence confocal microscopy. The insertion of the enhanced cyan fluorescent protein into the large intrace ...
The anthrax toxin is composed of three independent polypeptide chains. Successful intoxication only occurs when heptamerization of the receptor-binding polypeptide, the protective antigen (PA), allows binding of the two enzymatic subunits before endocytosi ...
The central goal of this thesis work is to fabricate novel, functional fluorescent nanostructures in confined systems offered by phospholipid membranes, which are known to have highly ordered, thermotropic and lyotropic structures. In separate approaches, ...
A biocompatible interface was constructed on a microchip by using the layer-by-layer (LBL) assembly of charged polysaccharides incorporating proteases for highly efficient proteolysis. The controlled assembly of natural polyelectrolytes and the enzyme-adso ...
Chem. and biol. labeling is fundamental for the elucidation of the function of proteins within biochem. cellular networks. In particular, fluorescent probes allow detection of mol. interactions, mobility and conformational changes of proteins in live cells ...
We show that it is possible to immobilize membrane proteins uniformly and reversibly as self-assembled (sub)monolayers on nitrilotriacetic acid-covered sensor surfaces via hexahistidine sequences present either in the protein or in lipid membranes. Fourier ...
