Membrane Protein Structural Biology Group
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 disease.
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.
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.
The focus of our group is eukaryotic and prokaryotic proteins that are linked to ion homeostasis and in particular transport of transition metals across cellular membranes. Our current targets include P-type ATPases of class IB (see figure) but also ion channels of various kinds. Underscoring the significance of these types of proteins, malfunctioning of the two human class IB P-type ATPases give rise to the severe Menkes’ and Wilson’s diseases, respectively.
The structural studies are complemented with biochemical characterization in vivo (complementation) and in vitro, using for example ICP-MS, EXAFS, ITC, thermophoresis and molecular dynamics simulations in our own group and in association with a network of international partners.

Kamil Gotfryd, PhD, Associate Professor
Obtained his MSc degree in Biotechnology at Jagiellonian University in Cracow, Poland. Afterwards, he moved to Denmark and joined a PhD programme at the Protein Laboratory at Copenhagen University. After gaining his PhD, he continued his scientific career in the Molecular Neuropharmacology Group headed by Prof. Ulrik Gether. Kamil engaged in structure-function studies of neurotransmitter:sodium:symporters, a protypical class of secondary active ion-coupled transporters conserved from bacteria to man, focusing on mechanistic characterization of the leucine transporter (LeuT). He now works as an associate professor in our group at Copenhagen University studying biomedically-important targets implicated in human metabolism.
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.
Ping Li, PhD, post-doc.
Ping took his PhD in Tianjin Key Laboratory of Protein Science, Nankai University, China, and then moved to the Institute of Molecular and Cell Biology in Singapore, where he focused on structural studies of a two-component sensor. He is now working in our group at Lund University, focusing on proteins linked to copper transport across cellular membranes. His main scientific interest regards the elucidation of copper uptake and resistance, therefore his project focuses on structural and functional studies of proteins associated with prokaryotic copper flux across cellular membranes. In his spare time, he enjoys watching and playing football.
