Many signals in the cell are conveyed by interacting protein molecules. How do protein-protein interactions lead to a response? The most likely explanation is through changes in structure. We study protein-protein interactions in the control of signalling processes using electron microscopy and combining the results with information from X-ray diffraction and biophysical studies.

    Zoom Science - Phonons dans la glace VII et VIII : courbes de dispersion et désordre hydrogène

    Les glaces VII et VIII sont les phases dominantes de l’eau solide car elles sont stables sur une énorme plage de pression, entre 2 et 50 GPa, et il n’est pas improbable qu’on les trouve à l’intérieur de quelques exoplanètes. En collaboration avec le CEA et l’ESRF, les chercheurs de l’IMPMC ont déterminé...
