Membrane Transport Group

Group leader: Hugues Nury


The group aims to understand membrane protein activity mechanisms at molecular and atomic level. The group is interested in high resolution structure determination, functional characterization and new approaches for membrane protein crystallization.

The membrane transport group is composed of 2 teams :

Key words

Production, characterization and crystallization of membrane proteins, Nucleotide transporter, AAC, NTT, Cys-loop transporter family, Serotonin receptor 5-HT3, Microorganism rhodopsins, Connexines

Specialized techniques

  • Overexpression (prokaryotes and eukaryotes systems) and purification of membrane proteins
  • Biophysical, biochemical and functional characterizations (thermal stability, FTIR, transport)
  • Membrane protein crystallization with vapor diffusion and lipidic phase (HTMPC platform)
  • X-ray crystallography
  • Electron microscopy
