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 (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 ...
Eukaryotic cells are organized into a complex system of subcompartments, each with its distinct protein and lipid composition. A continuous flux of membranes crosses these compartments, and in some cases direct connections exist between the different organ ...
Cripto is a glycosylphosphatidylinositol (GPI)-anchored co-receptor of Nodal and several other transforming growth factor-beta (TGF-beta) family ligands. It contains an epidermal growth factor (EGF)-like motif and a Cripto-FRL1-Cryptic (CFC) domain, which ...
The Golgi complex (GC) represents the central junction for membrane trafficking. Protein and lipid cargoes continuously move through the GC in both anterograde and retrograde directions, departing to and arriving from diverse destinations within the cell. ...
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 ...
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 ...
Despite the importance of trafficking for regulating G protein-coupled receptor signaling, for many members of the seven transmembrane helix protein family, such as odorant receptors, little is known about this process in live cells. Here, the complete lif ...
Interleukin-1 receptor (IL-1RI) is a master regulator of inflammation and innate immunity. When triggered by IL-1beta, IL-1RI aggregates with IL-1R-associated protein (IL-1RAcP) and forms a membrane proximal signalosome that potently activates downstream s ...
The GABA-synthesizing enzyme GAD65 is synthesized as a soluble cytosolic protein but undergoes post-translational modification(s) to become anchored to the cytosolic face of Golgi membranes before targeting to synaptic vesicle membranes in neuroendocrine c ...
Following endocytosis, ubiquitinated signaling receptors are incorporated within intraluminal vesicles of forming multivesicular endosomes. These vesicles then follow the pathway from early to late endosomes, remaining within the endosomal lumen, and are e ...
