Membrane protein folding.

Investigating the in vitro refolding of proteins that naturally reside in biological membranes is a notoriously difficult task. Biophysical studies on model systems are beginning to provide a sound physical basis for membrane protein folding that should help to alleviate this problem. Highlights of these studies include insights into the interaction of transmembrane alpha helices, as well as into the important role that membrane lipids play in folding.
