Progress in understanding the role of lipids in membrane protein folding

Detailed investigations of membrane protein folding present a number of serious technical challenges. Most studies addressing this subject have emphasized aspects of protein amino acid sequence and structure. While it is generally accepted that the interplay between proteins and lipids plays an important role in membrane protein folding, the role(s) played by membrane lipids in this process have only recently been explored in any detail. This review is intended to summarize recent studies in which particular lipids or membrane physical properties have been shown to play a role in the folding of intact, functionally competent integral membrane proteins. This article is part of a Special Issue entitled: Protein Folding in Membranes.

► Works which specifically examine lipids in membrane folding are reviewed. ► Focus on alpha helical proteins, beta barrels and membrane protein topogenesis. ► Focus on folding of intact, functional membrane proteins.
