Membrane proteins can deform the lipid bilayer in which they are embedded. If the bilayer is treated as an elastic medium, then these deformations will generate elastic interactions between the proteins. The interaction between a single pair is repulsive. However, for three or more proteins, we show that there are nonpairwise forces whose magnitude is(More)
Highly wedge-shaped integral membrane proteins, or membrane-adsorbed proteins can induce long-ranged deformations. The strain in the surrounding bilayer creates relatively long-ranged forces that contribute to interactions with nearby proteins. In contrast, to direct short-ranged interactions such as van der Waal's, hydrophobic, or electrostatic(More)
The elastic interaction of membrane inclusions provides one of the simplest physical realizations of multibody forces. Here we show how the cross-sectional shape of the inclusion greatly changes the character of the interaction, and illustrates a pattern formation mechanism. The formalism provides a transparent framework for modeling bilayer-inclusion(More)
The elastic interaction of membrane inclusions provides a unique physical realization of multibody forces. We derive an expression for the multibody curvature interaction between membrane proteins, and show that this interaction cannot be approximated by a pairwise additive theory. However, the interaction can be decomposed into a repulsive pairwise part(More)
INTRODUCTION Nanostructured materials represent a fascinating class of materials whose structural components, such as crystallites, atomic clusters or molecules, have at least one dimension between 1 nm and 100 nm. This size range is often equal to or smaller than the length scale that defines the physical characteristics of materials and at which(More)
