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 ...

Theoretical model for the formation of caveolae and similar membrane invaginations [PDF]

open access: yes, 2004
We study a physical model for the formation of bud-like invaginations on fluid lipid membranes under tension, and apply this model to caveolae formation.

Membrane curvature induces cardiolipin sorting [PDF]

open access: yes, 2019
International audienceCardiolipin is a cone-shaped lipid predominantly localized in curved membrane sites of bacteria and in the mitochondrial cristae. This specific localization has been argued to be geometry-driven, since the CL's conical shape relaxes

Structural Modifications Controlling Membrane Raft Partitioning and Curvature in Human and Viral Proteins [PDF]

open access: yes, 2020
Membrane proteins and lipids have the capacity to associate into lateral domains in cell membranes through mutual or collective interactions. Lipid rafts are functional lateral domains that are formed through collective interactions of certain lipids and

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.

Membrane curvature induced by proximity of anionic phospholipids can initiate endocytosis

open access: yesNature Communications, 2017
The plasma membrane is enriched in phosphatidylserine (PtdSer) mostly localized at the inner leaflet, which is predicted to induce membrane curvature.

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.

Out-of-equilibrium mechanochemistry and self-organization of fluid membranes interacting with curved proteins

open access: yesNew Journal of Physics, 2019
The function of biological membranes is controlled by the interaction of the fluid lipid bilayer with various proteins, some of which induce or react to curvature.

Transmembrane domain length is responsible for the ability of a plant reticulon to shape endoplasmic reticulum tubules in vivo [PDF]

open access: yes, 2010
Reticulons are integral endoplasmic reticulum (ER) membrane proteins that have the ability to shape the ER into tubules. It has been hypothesized that their unusually long conserved hydrophobic regions cause reticulons to assume a wedge-like topology ...

Curvature-Driven Migration of Colloids on Tense Lipid Bilayers

open access: yes, 2016
Inspired by proteins that generate membrane curvature, sense the underlying membrane geometry, and migrate driven by curvature gradients, we explore the question: Can colloids, adhered to lipid bilayers, also sense and respond to membrane geometry?
