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.
Polypropionates are common products of metabolism in bacteria, insects, fungi and marine organisms. They constitute an important class of products with a wide range of interesting biological activities. Our group has shown previously that 1-alkoxy-3-acylox ...
Proper regulation of cell division is crucial to most organisms. Asymmetric division and unequal cleavage are one of the many mechanisms by which spatial regulation of cell division might be achieved. Indeed, by varying its polarity cues or by modulating t ...
The L-3-hydroxy-4-methoxy-5-methylphenylalanol, a common subunit of ecteinascidin and safracin family alkaloids, was synthesized from L-tyrosine in eight steps with an overall yield of 50%. [on SciFinder (R)] ...
Protein kinase CK2 (casein kinase 2) is a eukaryotic serine/threonine protein kinase with multiple substrates and roles in diverse cellular processes, including differentiation, proliferation, and translation. The mammalian holoenzyme consists of two catal ...
Heterotrimeric G-proteins are integral to a conserved regulatory module that influences metazoan asymmetric cell division (ACD). In the Caenorhabditis elegans zygote, GOA-1 (Galpha(o)) and GPA-16 (Galpha(i)) are involved in generating forces that pull on a ...
The serum-amyloid-P-component-like pentraxin from Limulus polyphemus, a recently discovered pentraxin species and important effector protein of the hemolymph immune system, displays two distinct doubly stacked cyclic molecular aggregations, heptameric and ...
Calcium regulates neuronal signaling and viability through a vast range of cellular and molecular mechanisms. However, many details of these mechanisms still remain to be elucidated. It is believed that calcium-related pathways may comprise promising thera ...
The mechanism of signal transduction in G-protein-coupled receptors (GPCRs) is a crucial step in cell signaling. However, the molecular details of this process are still largely undetermined. Carrying out submicrosecond molecular dynamics simulations of be ...
Clathrin-dependent endocytosis is mediated by a tightly regulated network of molecular interactions that provides essential protein-protein and protein-lipid binding activities. Here we report the hydrolysis of the alpha- and beta2-subunits of the tetramer ...

Gene expression changes are a hallmark of the neuropathology of Huntington's disease (HD), but the exact molecular mechanisms of this effect remain uncertain. Here, we report that in vitro models of disease comprised of primary striatal neurons expressing ...
