Membrane curvature: a case of endofeelin’…
Trends in Cell Biology, 2002Abstract Endophilin A1, a cytoplasmic protein essential for the budding and fission of synaptic vesicles from presynaptic plasma membranes, is implicated in the generation of membrane curvature. Endophilin A1 exhibits intrinsic lysophosphatidic acid acyl transferase activity, reflecting its interaction with both the hydrophobic portion and the ...

Double curvature membrane lens
Applied Optics, 2020The paper presents a theoretical analysis of properties of a specific liquid membrane lens composed of two axially symmetric membranes of different thicknesses and double curvature. These membranes enclose a space where an optical liquid is filled. Mechanical and optical properties of the lens are then changed by varying the volume of the liquid.

Epsin: Inducing membrane curvature
The International Journal of Biochemistry & Cell Biology, 2007Epsin was originally discovered by virtue of its binding to another accessory protein, Eps15. Members of the epsin family play an important role as accessory proteins in clathrin-mediated endocytosis. Epsin isoforms have been described that differ in intracellular site of action and/or in tissue distribution, although all epsins essentially contribute ...

Modulation of membrane curvature by peptides
Biopolymers, 2000The fusion of two stable bilayers likely proceeds through intermediates in which the membrane acquires curvature. The insertion of peptides into the membrane will affect its curvature tendency. Studies with a number of small viral fusion peptides indicate that these peptides promote negative curvature at low concentration.

The influence of curvature on membrane domains
European Biophysics Journal, 2008An interdependence between local curvature and domain formation has been observed in both cell and model membranes. An implication of this observation is that domain formation in model membranes may be modulated by membrane curvature. In this paper, small-angle neutron scattering (SANS) is used to examine the influence of membrane curvature (i.e ...

On the curvature effect of thin membranes
Journal of Computational Physics, 2013We investigate the curvature effect of a thin, curved elastic interface that separates two subdomains and exerts a pressure due to a curvature effect. This pressure, which we refer to as interface pressure, is similar to the surface tension in fluid mechanics.

Curvature and spatial organization in biological membranes
Soft Matter, 2007Cellular membranes bend and curve into a multitude of shapes as they perform various functions. These deformations make use of the remarkable material properties of biological membranes inherent in their nature as two-dimensional fluids. The curvature of membranes is controlled by the constituent proteins and lipids, but conversely, curvature itself ...

Membrane curvature and mechanisms of dynamic cell membrane remodelling
Nature, 2005Membrane curvature is no longer seen as a passive consequence of cellular activity but an active means to create membrane domains and to organize centres for membrane trafficking. Curvature can be dynamically modulated by changes in lipid composition, the oligomerization of curvature scaffolding proteins and the reversible insertion of protein regions ...

Mechanisms of Membrane Curvature Sensing
Annual Review of Biochemistry, 2011Bacteria and eukaryotic cells contain geometry-sensing tools in their cytosol: protein motifs or domains that recognize the curvature, concave or convex, deep or shallow, of lipid membranes. These sensors contrast with classical lipid-binding domains by their extended structure and, sometimes, counterintuitive chemistry.

Anisotropic spontaneous curvatures in lipid membranes
Physical Review E, 2014Symmetry restrictions due to fluidity require the strain energy in the Helfrich theory of lipid membranes to be locally isotropic in nature. Although this framework is suitable for modeling the interaction of membranes with proteins that generate spherical curvature such as clathrin, there are other important membrane-bending proteins such as BIN ...
