Gourdon Group - Membrane Protein Structural Biology

The Membrane Protein Structural Biology Group works on structural and functional characterizing of membrane proteins that are essential for human health and highly attractive targets in the treatment of diseases.










The focus of our group is eukaryotic and prokaryotic membrane proteins that are linked to ion homeostasis and in particular transport of transition metals across cellular membranes. Our current targets include P-type ATPases aquaporins and ion channels of various kinds. Underscoring the significance of these types of proteins, malfunctioning of different membrane proteins have been associated with diseases ranging from brain edema, to cancer, and neurodegenerative diseases.

The overarching aim is to reveal the molecular principles and determinants of transport processes across cellular membranes for these proteins. To this end, we use a number of complementary techniques centered on X-ray crystallography and cryo-EM using the latest techniques to study structure-function-disease relationships of membrane proteins.

The group is based at the University of Copenhagen in Denmark and at Lund University in Sweden.



Membrane proteins are of critical importance to nearly every aspect of cell physiology, comprising about one-third of all proteins. Compared to soluble proteins, however, an understanding at the molecular-level for the membrane bound counterparts lags far behind. This lack of structural knowledge significantly impairs our understanding of the functions and mechanisms of these proteins, hereby preventing further applied, biomedical and biotechnological research.

Kaituo Wang

Kaituo Wang, PhD, Assistant Professor

Took his PhD in Prof. Xiao-Dong Su’s laboratory at the prestigious Peking University (China), and then went on to Prof. Poul Nissen's group in Aarhus (Denmark). Kaituo's efforts were essential for recovering the first crystal structures of a zinc-transporting P-type ATPase that were published in Nature recently. Now at University of Copenhagen and at UCLA (through a collaboration with the group of Prof. Zhou Hong), he continues this work, while at the same time focusing on structural and functional characterization of other proteins involved in ion flux across cellular membranes. Kaituo loves Chinese delicacies and perhaps somewhat surprisingly, he is also a big fan of karaoke and Danish rugbrød.

Kristian obtained his PhD in 2016 from Prof. Leila Lo Leggio’s group at Department of Chemistry, University of Copenhagen focusing on X-ray crystallography to structurally characterize copper-dependent fungal oxidases, denoted LPMOs, which are involved in plant cell wall biomass conversion and plant pathogenicity, but also in lethal meningitis in humans via interactions with Ctr1 copper transporters. Kristian worked as a postdoc (2017-2019) at the French National Institute of Agricultural Research (INRAE) in Marseille, before returning to University of Copenhagen and Department of Plant and Environmental Sciences (PLEN) in 2020. He is currently employed as an Assistant Professor and works in close collaboration with the Gourdon group focusing on cryo-EM and modelling of plant polysaccharide-synthesizing enzymes and their microtubule binding interaction partners, which are structurally and functionally related to hyaluronan synthases and intrinsically disordered proteins involved in mammalian neurobiology, respectively.
