Local membrane curvature affects spontaneous membrane fluctuation characteristics
Molecular Membrane Biology, 2003Mechanical fluctuations on erythrocyte cell membranes wee measured by phase-contrast optics at the cell centre and cel rim. Intensity changes were digitized by a linear charge-coupled device array and both frequency spectra and autocorrelation functions were calculated to detect fluctuation characteristics at these areas.

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.

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.

How proteins produce cellular membrane curvature
Nature Reviews Molecular Cell Biology, 2005Biological membranes exhibit various function-related shapes, and the mechanism by which these shapes are created is largely unclear. Here, we classify possible curvature-generating mechanisms that are provided by lipids that constitute the membrane bilayer and by proteins that interact with, or are embedded in, the membrane.

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 ...

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 ...

TRANSDUCER MEMBRANE WITHSYMMETRICAL CURVATURE
The Journal of the Acoustical Society of America, 2013A transducer membrane enhances sound reproduction. Curved portions of the membrane periphery contribute to the enhanced sound reproduction. The transducer membrane may add or improve sound reproduction capability in cell phones, gaming systems, personal data assistants, or other devices.

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 ...
