Intrinsically Disordered Proteins Drive Membrane Curvature [PDF]

open access: yesBiophysical Journal, 2015
Abstract Assembly of highly curved membrane structures is essential to cellular physiology. The prevailing view has been that proteins with curvature-promoting structural motifs, such as wedge-like amphipathic helices and crescent-shaped BAR domains, are required for bending membranes.

Revealing the Effects of Nanoscale Membrane Curvature on Lipid Mobility

open access: yesMembranes, 2017
Recent advances in nanoengineering and super-resolution microscopy have enabled new capabilities for creating and observing membrane curvature. However, the effects of curvature on single-lipid diffusion have yet to be revealed. The simulations presented

Influenza A matrix protein M1 induces lipid membrane deformation via protein multimerization [PDF]

open access: yes, 2019
The matrix protein M1 of the Influenza A virus (IAV) is supposed to mediate viral assembly and budding at the plasma membrane (PM) of infected cells. In order for a new viral particle to form, the PM lipid bilayer has to bend into a vesicle toward the ...

Membrane Curvature Sensing by Amphipathic Helices Is Modulated by the Surrounding Protein Backbone. [PDF]

open access: yesPLoS ONE, 2015
Membrane curvature is involved in numerous biological pathways like vesicle trafficking, endocytosis or nuclear pore complex assembly. In addition to its topological role, membrane curvature is sensed by specific proteins, enabling the coordination of ...

Analyzing the cellular plasma membrane by fast and efficient correlative STED and platinum replica EM

open access: yesFrontiers in Cell and Developmental Biology, 2023
The plasma membrane of mammalian cells links transmembrane receptors, various structural components, and membrane-binding proteins to subcellular processes, allowing inter- and intracellular communication.

Induction of spontaneous curvature and endocytosis: Unwanted consequences of cholesterol extraction using methyl-β-Cyclodextrin

open access: yesCommunicative & Integrative Biology, 2018
Membrane curvature is a property of biological membranes essential for organelle morphology and the formation of tubulovesicular carriers. Curvature generation is influenced by the lipid composition of the membrane and protein-mediated processes.

Protein-Induced Membrane Curvature Alters Local Membrane Tension [PDF]

open access: yesBiophysical Journal, 2014
Adsorption of proteins onto membranes can alter the local membrane curvature. This phenomenon has been observed in biological processes such as endocytosis, tubulation, and vesiculation. However, it is not clear how the local surface properties of the membrane, such as membrane tension, change in response to protein adsorption. In this article, we show

Role of disclinations in determining the morphology of deformable fluid interfaces [PDF]

open access: yes, 2012
We study the equilibrium shapes of vesicles, with an in-plane nematic order, using a Monte-Carlo scheme and show that highly curved shapes, like tubes and discs, with a striking similarity to the structures engendered by certain curvature sensing ...

Alterations of membrane curvature during influenza virus budding [PDF]

open access: yes, 2014
Influenza A virus belongs to the Orthomyxoviridae family. It is an enveloped virus that contains a segmented and negative-sense RNA genome. Influenza A viruses cause annual epidemics and occasional major pandemics, are a major cause of morbidity and ...

Membrane curvature sorts lipids [PDF]

open access: yesEMBO reports, 2005
The enrichment of sphingolipids and cholesterol in the mammalian plasma membrane, and unsaturated phosphatidylcholine (PC) in the endoplasmic reticulum, requires lipid sorting in the Golgi apparatus. Most sphingolipids are synthesized in the Golgi lumen (Holthuis & Levine, 2005).
