Marie Skepö, Associate Professor and Deputy Head of the Division

Grant for Neutron Research awarded by NordForsk

Marie Skepö (PI), has in collaboration with Lise Arleth and Kresten Lindorff-Larsen at University of Copenhagen, and Jens Preben Morth at University of Oslo, been awarded 6.8 MNOK for studying the structure of membrane proteins under solution conditions. The aim is to understand how the lipid environment influences the activity of membrane proteins, using the active transporter MgtA as benchmark system, and to investigate the dynamic fluctuations between lipid and protein in solution, utilising neutron and X-ray scattering in combination with computer simulations.
