abstract = {The effects of embedded proteins on the dynamical
properties of lipid bilayer membranes are studied in shear
flow. Coarse-grained molecular simulations are employed, in
which lipids are modeled as short polymers consisting of
hydrophilic head groups and hydrophobic tail monomers;
similarly, transmembrane proteins are modeled as connected
hydrophobic double- or triple-chain molecules with
hydrophilic groups at both ends. In thermal equilibrium,
rigid proteinlike molecules aggregate in a membrane of
flexible lipids, while flexible proteins do not aggregate.
In shear flow parallel to the membrane, the monolayers of
lipid bilayer slide over each other. The presence of
transmembrane proteins enhances the intermonolayer friction.
The friction coefficient depends on the chain lengths of
lipids, the membrane tension, the length of the protein, and
the cluster size. It is found to increase with protein
length (with positive mismatch, i.e., proteins which are
longer than the membrane thickness) and protein cluster
size. In flow, proteins get oriented in the flow direction
to reduce friction, with large fluctuations of the
orientation angle.},
