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.

The fate of pluripotent cells in early mouse embryos is controlled by graded Nodal signals that are activated by the endoproteases Furin and Pace4. Soluble forms of Furin and Pace4 cleave proNodal in vitro and after secretion in transfected cells, but dire ...

Visualization of proprotein convertase activity in living cells and tissues

Daniel Constam

The invention relates to a system for detecting the presence of a convertase cleaving activity, the system comprising a molecule comprising a proteolytic cleavage site with the amino acid sequence -R-X1-X2-R-, wherein R represents the amino acid arginine, ...

More than forty per cent of the mammalian genome is derived from retroelements, of which about one-quarter are endogenous retroviruses (ERVs). Some are still active, notably in mice the highly polymorphic early transposon (ETn)/MusD and intracisternal A-ty ...

Nature Publishing Group2010

Axis formation and allocation of pluripotent progenitor cells to the germ layers are governed by the TGF-β-related Nodal precursor and its secreted proprotein convertases (PCs) Furin and Pace4. However, when and where Furin and Pace4 first become active ha ...

Polycystic diseases and left-right (LR) axis malformations are frequently linked to cilia defects. Renal cysts also arise in mice and frogs lacking Bicaudal C (BicC), a conserved RNA-binding protein containing K-homology (KH) domains and a sterile alpha mo ...

Intracellular trafficking and signaling in development

Daniel Constam

Tissue patterning during development relies on cell communication by secreted proteins and receptors that engage in complex signaling crosstalk to induce distinct cell behaviors in a context-dependent fashion. Here I summarize recent insights into basic me ...

2009

A fundamental challenge in biology is to explain how progenitor cells in developing tissues acquire distinct fates according to their position. In vertebrates, the positional information that specifies the germ layers and the primary body axes is mediated ...

Riding shotgun: a dual role for the epidermal growth factor-Cripto/FRL-1/Cryptic protein Cripto in Nodal trafficking

Daniel Constam

Nodal is a secreted protein of the transforming growth factor beta (TGFbeta) family that activates Smad2 and Smad3 transcription factors through complexes of type I and type II activin receptors and glycosyl-phosphatidylinositol-anchored coreceptors of the ...

Cripto promotes A-P axis specification independently of its stimulatory effect on Nodal autoinduction

Daniel Constam

The EGF-CFC gene cripto governs anterior-posterior (A-P) axis specification in the vertebrate embryo. Existing models suggest that Cripto facilitates binding of Nodal to an ActRII-activin-like kinase (ALK) 4 receptor complex. Cripto also has a crucial func ...

Rockefeller University Press2008

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 ...
