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.
Gamma-secretase is an intramembrane-cleaving protease responsible for the final proteolytic event in the production of the amyloid-beta peptides (Abeta) implicated in Alzheimer's disease (AD). Inhibition of gamma-secretase activity is thus an attractive th ...
Peptides are an attractive class of molecules for the development of therapeutics because they combine unique properties such as high binding affinity, excellent target specificity, low toxicity and a relatively small mass. However, the short in vivo half- ...
The rules for product ion formation in electron capture dissociation (ECD) mass spectrometry of peptides and proteins remain unclear. Random backbone cleavage probability and the nonspecific nature of ECD toward amino acid sequence have been reported, cont ...
Molecular probes for selective Identification of protein aggregates are important to advance our understanding of the molecular pathogenesis underlying cerebral amyloidoses. Here we report the chemical design of pentameric thiophene derivatives, denoted lu ...
The coiled coil is a superhelical protein structural motif that consists of two or more alpha-helical peptides that are wrapped around each other in superhelical fashion. Coiled coils are amongst the most ubiquitous folding motifs found in proteins and hav ...
The preparation of synthetic polymers with exact control over chain length and monomer sequence is one of the long-standing challenges in polymer science. Nature perfectly masters the synthesis of high molecular weight, perfectly monodisperse polypeptides ...
Coupling fast triplet-triplet energy transfer (TTET) between xanthone and naphthylalanine to the helix-coil equilibrium in alanine-based peptides allowed the observation of local equilibrium fluctuations in alpha-helices on the nanoseconds to microseconds ...
Hydrophilic/hydrophobic patterning is a powerful strategy to control folding in non-natural polymers/oligomers. In this contribution, we present a novel strategy for the preparation of alternating hydrophilic/hydrophobic patterned non-natural peptide folda ...
Centrin, an EF-hand calcium-binding protein, has been shown to be involved in the duplication of centrosomes, and Sfi1 (Suppressor of fermentation-induced loss of stress resistance protein 1) is one of its centrosomal targets. There are three isoforms of h ...
Parkinson's disease (PD) is associated with the deposition of fibrillar aggregates of the protein alpha-synuclein (alphaS) in neurons. Intramolecular contacts between the acidic C-terminal tail of alphaS and its N-terminal region have been proposed to regu ...
