Abstract:
This review describes: (i) perturbations of the membrane lipids that are induced by integral membrane proteins, and reciprocally, (ii) the effects that the lipids may have on the function of membrane-associated proteins. Topics of the first category that are covered include: stoichiometry and selectivity of the first shell of lipids associated at the intramembranous perimeter of transmembrane proteins; the chain configuration and exchange rates of the first-shell lipids; the effects of transmembrane peptides on transbilayer movement of lipids (flip-flop); the effects of membrane proteins on lipid polymorphism and formation of non-lamellar phases; and the effects of hydrophobic mismatch on lipid chain configuration, phase stability and selectivity of lipid-protein association. Topics of the second category are: the influence of lipid selectivity on conformational changes in the protein; the effects of elastic fluctuations of the lipid bilayer on protein insertion and orientation in membranes; the effects of hydrophobic matching on intramembrane protein-protein association; and the effects of intrinsic lipid curvature on membrane integration, oligomer formation and activity of membrane proteins.

Mosaic nature of the membrane
The mosaic characteristic of the membrane helps the plasma membrane remain fluid. The integral proteins and lipids exist as separate but loosely-attached molecules in the membrane. The membrane is a relatively...

Membrane Lipids
Phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, and sphingomyelin are the most common phospholipids present in mammalian membranes. At physiological pH, phosphatidylserine is negatively charged, while the other three...

The membrane comprises a group of distinct proteins responsible for carrying out a cell's specific function. For example, the plasma membrane of the human sperm, or a single germ cell, contains a unique set of proteins in the anterior...
