Offer Description

As part of an ANR project, the researcher will be responsible for conducting cell biology experiments (using insect and mammalian cells) and experiments on the expression of membrane proteins, in particular using recombinant viruses (baculoviruses or lentiviruses). The membrane protein of interest will be solubilised and purified using chromatography techniques. The quality of the sample will be verified using biochemical and biophysical methods. The structure will be determined by cryo-electron microscopy, and the researcher will process the images to reconstruct the structure of the protein of interest in complex with its interactants.
The researcher will be called upon to work in collaboration with the electron microscopy facilities at the institute and at partner institutes.

Located on the Grenoble Science Park (ESRF/ILL/EMBL/IBS), the Institute of Structural Biology (IBS) is a national and international player in the field of integrated structural biology. The IBS is a research center, a technical platform, a host site and a scientific training center. Its mission is to develop research in structural biology, a field of research that is crucial to the understanding of fundamental biological mechanisms. It is supported by 10 state-of-the-art platforms.
As a joint research unit (CEA-CNRS-UGA), the IBS is composed of 20 research groups, each of which proposes a multi-disciplinary approach, at the frontiers of biology, physics and chemistry, in coherence with 3 research axes. Nearly 320 people work there as researchers, PhD students, engineers and technicians in a multicultural and international environment.
The successful candidate will join the Membrane Group within the Moreau team, which has extensive expertise in the structure-function analysis and engineering of membrane proteins and comprises young, dynamic researchers ( https://www.ibs.fr/ fr/research/membrane-proteins-and-glycobiology/membrane-transport-group-h-nury/moreau-team/). The successful candidate will have access to the numerous facilities within and near the institute (including an insect cell culture facility) and to the expertise of the managers responsible for their operation
