In this project, we will study the mechanisms by which proteins of the Listeria monocytogenes phosphoenolpyruvate:carbohydrate phosphotransferase system (PTS), a transport system for numerou
Hormone and neurotransmitter receptors have long been considered to diffuse freely in the plasma membrane. Data accumulated these last few years revealed that these receptor are associated with their effectors and to other signaling proteins. These protein complexes called receptosomes play critical
In this project we propose to study through a combination of bioinformatics, genetic, biochemical and biophysical approaches the functions of three proteins involved in the maintenance of H. pylori genetic stability and genome plasticity: RecJ, RecN and PolA. The first two, supposedly involved in ho
Regulation of Hox protein function:insights from protein motifs and cofactors – Hox control
How animal body plans are specified is a central question in developmental and evolutionary biology. A major conclusion from animal model studies and from annotation of metazoan genomes is that a relatively small number of gene families encoding structurally related proteins underlies the amazing di
The efficient and accurate duplication of eukaryotic genomes depends on the sequential firing of thousands of replication origins distributed along the chromosomes. Origin activation follows a temporal program that is imposed by the chromosomal context and is controlled by S-phase checkpoints. The c
Dendritic cells (DCs) are key actors in most adaptive and memory immune responses as their function is to capture and process antigens from their environment and, after migration to lymphoid organs, to present them to effector T cells. Antigens can be taken from pathogens, infected cells or cancer c
The Cell.com project focuses on the study of a cell-cell communication system functioning in bacteria of the Bacillus cereus group (ie. B. anthracis, B. thuringiensis and B. cereus sensu stricto). This biological system functions according to a quorum-sensing mechanism involving a regulatory protein
Regulation of cell proliferation is perhaps the most fundamental control in biology, and when it goes wrong, the consequences are pathological. If we could restore correct proliferation control, many diseases, including cancers, could be eradicated. In all eukaryotes, this control is mediated by Cyc
The formidable evolutionary success of bacteria is illustrated by the fact that they inhabit almost all environmental niches on Earth. The new ecological niche is usually colonized by very small number of bacterial cells. When adaptive variants are not present among them, bacterial population will b
The serine/theronine kinase Aurora-A is a key player in mitosis. Although discovered in 1998 its functions are not fully understood yet. Inhibition of its activity by RNA interference leads to a defect in centrosome maturation and consequently the formation of abnormal spindles during mitosis. This
The study of metazoan phylogeny using molecular data has led to major reorganizations in our conception of the animal phylogenetic tree. The bilaterians (bilaterally symmetrical triploblastic animals) are a monophyletic group, divided into three great branches: the deuterostomes and two large groups
Cryptochromes are blue light sensing photoreceptors in plants and animals. Plant cryptochromes are undergo light dependent electron transfer reactions and are responsive to the geomagnetic field. However, nothing is known concerning mechanism of activation of human cryptochromes. In this proposal we
The Lambda-Cold Dark Matter hierarchical paradigm is robust to large scale observables, and it is on galactic scales that our understanding of the cosmological evolution of matter is most incomplete. Many of the predicted features of galaxies, such as faint satellites and diffuse stellar halo
The most conspicuous manifestations of the ongoing climate warming are found in the Arctic. Changes in this region outpace the most pessimistic climate model predictions. Summer sea ice extent has shrunk very substantially (ice cover 40% smaller in 2007 than the 1980-2000 median). Multiyear ice decl
The aim of OPALE is to establish the present-day oxidative capacity of the atmosphere over the Antarctic plateau, which appears to be unexpectedly strong due to the presence of the snow cover, to assess its influence on coastal Antarctica, and to forecast its future change in response to the recover
We propose the detailed study and prototyping of a Super-Station for the LOFAR radiotelescope (LSS). France is inthe process of purchasing a LOFAR station to be installed in Nançay.; it thus participates to the europeanization of this radiotelescope of new generation, precursor of SKA and other inst
Herschel Unveils Galaxy Evolution – HUGE
A decade ago, it was thought that the global star formation history of galaxies at cosmological scales was relatively well constrained by the optical and UV data. Soon after, 15 microns observations with ISOCAM, onboard the Infrared Space Observatory (ISO), and sub-millimeter SCUBA results from the
It is now well established that Mars' atmosphere evolved from an early Earth's like atmosphere 4 billions years ago to the present dry and thin atmosphere. However, we still ignore why and how most of the water, still present on Earth, disappeared from Mars' surface. Actually, we even do not know if
Atmospheric CO2 concentration has increasedby more than 30% since the pre-industrial era mainly due to industrial emissions and this increase is very likely at the root of the observed temperature rise of 0.6°C over the last century. Although we have good estimates of the CO2 fluxes on a global basi
This proposal seeks support for an integrated geochemical and modelling study of the Himalayan erosion and its interactions with climatic changes, in the present and in the past. Indeed, improving our understanding of the interactions between climate and the surface is one of the most challenging is
The presence of water (or hydrogen) in nominally-anhydrous mantle minerals, as well as its influence on the chemical and physical properties of these minerals, has been known for almost twenty years. Nevertheless, the total amount of water stored in the mantle is still very poorly constrained and th
This project is aimed at tracing the early evolution of the photosynthetic metabolisms of microorganisms, as preserved in the geological rock record, collected in ~3.5 to 2.1 Ga- old rock formations from South Africa and Canada. Anoxygenic photosynthesis is believed to have been the precursor oxygen
Prion pathology (Bovine Spongiform Encephalopathy, commonly known as Mad-Cow Disease, or Creutzfeldt-Jakob Disease for instance) and Alzheimer Disease are both characterized by accumulation of large protein polymers, so-called 'fibrils', in the brain. The key event in the pathogenesis is the convers
This project is targeted at elucidating the role of the fine control of the degree of methylesterification (DM) of the pectins of plant cell wall, and its impact on the regulation of the elongation capacity of a given organ. Pectins, which are rich in galacturonic acid, play a major role in regulati
In the flowering plants, it is well established that multimeric complex formed by MADS-box transcription factors (TFs) is responsible for the specification of petal organ identity. However, how organ identity is translated into specific growth patterns to generate organs with characteristic shapes a
Life in an oxygen-rich atmosphere has to deal with the danger of oxidative stress. Plants are especially exposed to oxidative stress caused by photosynthetic processes. Reactive oxygen species (ROS) are produced during normal cell metabolism but their production is drastically enhanced when plants a
Spray cooling is used in an increasing numbers of industrial applications. In the steel industry, during heat treatment of alloys, very high quenching rates are required to obtain strong and hard bonding in the metallurgical microstructure. The main purpose of this project is to deliver new models o
The current major challenge for climate science is to provide policymakers with better constrained scenarios of the Earth climatic evolution over the 21st century and beyond. This requires improving our understanding of both the climate forcings in the future and the climate sensitivity. This projec
Expanding from single component nanoparticles, research in nanomaterials now focuses on multi-component NPs with discrete domains of different materials arranged in a controlled manner. This evolution is driven by the obvious advantages of multifunctionality, the possibility to create novel function
The X-linked gene Nap1l2/NAP1L2 encodes a protein that shows similarities to the nucleosomal assembly (NAP) and SET proteins. The gene is specifically expressed in nestin positive neural stem cells and neurons, with targeted deletion of the murine gene leading to embryonic lethality associated with
