Membrane curvature induced by proximity of anionic phospholipids can initiate endocytosis
Nature Communications, 2017 The plasma membrane is enriched in phosphatidylserine (PtdSer) mostly localized at the inner leaflet, which is predicted to induce membrane curvature.

Modeling Membrane Morphological Change during Autophagosome Formation
iScience, 2020 Summary: Autophagy is an intracellular degradation process that is mediated by de novo formation of autophagosomes. Autophagosome formation involves dynamic morphological changes; a disk-shaped membrane cisterna grows, bends to become a cup-shaped ...

Interactions of human islet amyloid polypeptide with lipid structure of different curvatures
Theoretical and Applied Mechanics Letters, 2020 : Curvature is one of the most important features of lipid membranes in living cells, which significantly influences the structure of lipid membranes and their interaction with proteins.

Curvature-induced stiffening of a fish fin [PDF]
, 2017 How fish modulate their fin stiffness during locomotive manoeuvres remains unknown. We show that changing the fin's curvature modulates its stiffness. Modelling the fin as bendable bony rays held together by a membrane, we deduce that fin curvature is ...

The membrane inclusions curvature equations
Advances in Applied Mathematics, 2003 We examine a system of equations arising in biophysics whose solutions are believed to represent the stable positions of $N$ conical proteins embedded in a cell membrane. Symmetry considerations motivate two equivalent refomulations of the system which allow the complete classification of solutions for small $N

Anisotropic Membrane Curvature Sensing by Amphipathic Peptides [PDF]
Biophysical Journal, 2016 Many proteins and peptides have an intrinsic capacity to sense and induce membrane curvature, and play crucial roles for organizing and remodelling cell membranes. However, the molecular driving forces behind these processes are not well understood.

Single Lipid Molecule Dynamics on Supported Lipid Bilayers with Membrane Curvature
Membranes, 2017 The plasma membrane is a highly compartmentalized, dynamic material and this organization is essential for a wide variety of cellular processes. Nanoscale domains allow proteins to organize for cell signaling, endo- and exocytosis, and other essential ...

Curvature-coupling dependence of membrane protein diffusion coefficients
, 2007 We consider the lateral diffusion of a protein interacting with the curvature of the membrane. The interaction energy is minimized if the particle is at a membrane position with a certain curvature that agrees with the spontaneous curvature of the ...

The influence of solid scaffolds on flat and curved lipid membranes
AIP Advances, 2017 Solid-supported membranes have become a common tool to study lipid membrane properties in a controlled environment. One particular example is the study of membrane curvature and its effect on lipid sorting.
