Cell membranes are critical components of all living cells. The Centre for Biomembrane Research conducts unique research on the proteins that constitute a large part of these membranes. The majority of the future pharmaceutical drugs are expected to target membrane proteins, and many central processes in the cell are dependent on such proteins. This is related to the membranes' function to regulate what substances pass in and out of the cell. Membrane proteins are thus the focus of many research groups, both in Sweden and internationally. What makes the Centre for Biomembrane Research (CBR) unique is the considerable breadth of research. There are more than twenty research groups with both experimental and theoretical emphases on cell biology, molecular biology, biophysics, bioinformatics, biotechnology, etc. The Centre’s studies include how membrane proteins are structured, how they are produced inside the cell, how they move, and what role they play in the cell's energy metabolism.
