Intitulé du poste : Post-doc Architecture of membrane contact site by cryo-electron microscopy
Ville : Paris
Laboratoire/Institut : Institut Curie
Description du poste : A 24 months post-doctoral position is available in the team of Molecular Microscopy of Membranes at the Department of Physico-Chemistry of the Institute Curie.

The project aims on decrypting the structural and functional architecture of membrane contact sites (MCS) between ER and Golgi. For a few years, MCS between ER and other organelles have been continuously discovered leading to the idea that ER is connected to all other cellular organelles, suggesting an alternative way of inter-organelle communication to the trafficking mediated by vesicles. MCSs are constituted by protein complexes that tether two facing organelles and associated so far to exchange lipids, calcium or apoptosis signaling. Since the assembly of proteins of MCS requires two facing lipidic membranes, structural analysis have been yet limited but the current revolution of cryo-EM in single particles analysis or cryo-electron tomography modes allows now to tackle the complete architecture of MCSs.

The project is in collaboration with B. Mesmin, (team of B. Antonny, IPMC, Valbonne) and combines approaches of cell biology, membrane biochemistry and structural biology. B. Mesmin has purified and functionally characterized the first minimal MCS required for the cholesterol transport between ER and Golgi (Cell, 2013). We have already designed an in vitro MCS suitable for high resolution cryo-EM. The post-doc will now determine 3D models of MCSs from cryo-EM images by single particle analysis and by cryo-tomography and sub-tomogram averaging*.

Applicants are expected to have a training and research experience in structural biology and/or computational analysis and express a strong interest in working in structural electron microscopy. Crystallographers tempted by the dark side of the real space are welcome. A former experience in cryo-electron microscopy and/or image processing (single particle, tomography) is favorable but not mandatory. If needed, the post doc will be trained in cryo-EM, cryo-ET and images analysis. The position is funded by the French National Research Agency (ANR, France).

The project will be executed at the Institut Curie, a private non-profit organization created in 1909, and comprises of a research center and a hospital dedicated entirely to the care of cancer patients. The Institute Curie is an internationally recognized Institute for life science research. It houses more than 30 research groups that study numerous aspects of physics of the cell, cell biology, immunology, and cancer research. It is located in the center of Paris, in an area that concentrates several science institutes such as the Ecole Normale Supérieure, the Collège de France and the ESPCI, offering a large choice of seminars and possible scientific interactions. The EM facility includes a 200Kv FEG Jeol2200FS, a 200kV Technai with a F416 TVIPS camera and a 120kV FEI Spirit as well as funded access to the Titan Krios of the French FRISBI infrastructure and elsewhere.
