Nearly one-third of all proteins in living beings are firmly embedded in abiomembrane—either in a cell's outer membrane or in the boundaries of internal cellular compartments. There, thesemembrane proteinsperform important tasks, serving, for instance, as molecular channels for transporting metabolite...
Membrane proteins are proteins found in cell membranes, either at the surface or on intracellular organelles. Integral membrane proteins such as receptors and ion channels span the membrane. Peripheral membrane proteins, for example some signalling proteins, are tethered by an anchor, via a fatty aci...

Membrane detachment and release of the major membrane glycoprotein of secretory granules in rat pancreatic exocrine cells. The major glycoprotein of pancreatic zymogen granule membranes (GP-2) was detected in the medium of acinar cell suspensions from rat pancreas. Its release ... JR Havinga,JW Sl...
A third mode of membrane association is for the cell to attach hydrophobic tails to peripheral proteins. The tails then dissolve in the hydrophobic (nonpolar) core of the bilayer, thereby anchoring the protein. Typically, these tails are long hydrocarbon chains; frequently, they are the very same...
A number of viral membrane fusion proteins can be expressed alone on the surface of host cells, and then triggered to induce cell-to-cell fusion or syncytium formation. Although rapid and easily observed, syncytium formation is not easily quantified and differences in fusion activity are not ...
Structural basis of unidirectional export of lipopolysaccharide to the cell surface Crystal structures of a five-protein complex comprising the inner-membrane components of the bacterial lipopolysaccharide transporter provide insight into the mechanism of extraction of lipopolysaccharide from the inner membrane...
contour of the protein. Proteins that insert into the lipid bilayer can bend membranes by changing the spontaneous curvature of the local monolayer. In all cases, the most probable way to generate membrane curvature is to use a combination of the scaffold and local spontaneous curvature mechanisms...
