Structural and functional studies of membrane remodeling machines

Abstract

Building cells from their component parts will hinge upon our ability to reconstitute biochemical compartmentalization and exchange between membrane-delimited organelles. By contrast with our understanding of other cellular events, the mechanisms that govern membrane trafficking has lagged because the presence of phospholipid bilayers complicates the use of standard methods. This chapter describes in vitro methods for purifying, reconstituting, and visualizing membrane remodeling activities directly by electron cryomicroscopy.
