Graph Chatbot
Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
G Protein coupled receptors (GPCRs) constitute an abundant family of membrane proteins which play a central role in cellular signaling and are important targets for modern medicine. Despite intensive research, central questions of the molecular mechanism o ...
How membrane receptors transduce external signals across the membrane and activate intracellular processes is a key question for fundamental research and for therapeutic purposes. Reliable in situ investigations requiest to preserve the full biological act ...
G protein-coupled receptors (GPCRs) constitute a large class of seven transmembrane proteins, which bind selectively agonists or antagonists with important consequences for cellular signaling and function. Comprehension of the mol. details of ligand bindin ...
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 ...
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 ...
Many central biol. signal transduction processes such as synaptic transmission occur at the level of cell membranes. It is therefore not surprising that the biol. function of membrane proteins in general and neuroreceptors in particular can be modulated by ...
Membrane proteins fulfill many central functions in the biological membrane. The insertion process of these proteins and their structure, which are intimately linked to their function, are not yet well understood. As a model we studied three proteins recon ...
The specific and covalent labeling of fusion proteins with synthetic mols. opens up new ways to study protein function in the living cell. Here the authors present a novel method that allows for the specific and exclusive extracellular labeling of proteins ...
A general method for understanding the mechanisms of ligand recognition and activation of G protein-coupled receptors has been developed. A study of ligand-receptor interactions in the prototypic seven-transmembrane neurokinin-2 receptor (NK2) using this f ...
