Group presentation

Group leader : Hugues Nury

The group aims to understand signaling and transport across a biological membrane. To do so, we study membrane proteins at the molecular level with electrophysiology and structural techniques. The membrane transport group comprises four teams :

  • The Gordeliy lab combines an interest in rhodopsins with the development of in meso crystallization
  • The Moreau lab develops the Ion Channel-Coupled Receptor technology
  • The Nury lab focuses on pentameric ligand-gated ion channels
  • The Vivaudou lab studies the molecular mechanisms of ion channels, with a focus on inward-rectifying potassium channels

Publications of the group can be found here.
