Anisotropic Membrane Curvature Sensing by Amphipathic Peptides. [PDF]

Biophys J, 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.

Understanding Membrane Curvature Sensing [PDF]

, 2018
Eukaryotic cells are characterised by membranes with varied and dynamic compositions and shapes. Consequently, membrane-binding proteins are tuned to recognise and modify these membrane states to perform their functions. To study the curvature sensitivity of proteins, I have developed a single-particle assay using NanoSight technology that tracks the ...

Experimental validation of the mechanical coupling response for hygro-thermally curvature-stable laminated composite materials [PDF]

, 2011
Stacking sequence configurations for hygro-thermally curvature-stable (HTCS) laminates have recently been identified in 9 classes of coupled laminate with standard ply angle orientations +45, "1245, 0 and ...

Differential phase tracking applied to Bragg gratings in multi-core fibre for high accuracy curvature measurement [PDF]

, 2006
High resolution quasi-static and dynamic curvature measurements are made by differential interferometric phase measurement of fibre Bragg gratings in separate cores of a multi-core fibre.

Biophysical modeling of membrane curvature generation and curvature sensing by the glycocalyx. [PDF]

Proc Natl Acad Sci U S A
Generation of membrane curvature is fundamental to cellular function. Recent studies have established that the glycocalyx, a sugar-rich polymer layer at the cell surface, can generate membrane curvature. While there have been some theoretical efforts to understand the interplay between the glycocalyx and membrane bending, there remain open questions ...

Clathrin Senses Membrane Curvature [PDF]

Biophysical Journal, 2020
ABSTRACT The ability of proteins to sense membrane curvature is essential to diverse membrane remodeling processes including clathrin-mediated endocytosis. Multiple adaptor proteins within the clathrin pathway have been shown to assemble together at curved membrane sites, leading to local recruitment of the clathrin coat.

Quantification of Curvature Sensing Behavior of Curvature-Inducing Proteins on Model Wavy Substrates. [PDF]

J Membr Biol, 2022
Curvature-inducing proteins are involved in a variety of membrane remodeling processes in the cell. Several in vitro experiments have quantified the curvature sensing behavior of these proteins in model lipid systems. One such system consists of a membrane bilayer laid atop a wavy substrate (Hsieh in Langmuir 28:12838-12843, 2012). In these experiments,

Sensing Membrane Curvature [PDF]

Developmental Cell, 2003
AbstractTransport vesicle formation and fusion are highly regulated processes that require the sequential assembly and disassembly of proteinacious membrane coats. Recent work suggests that one of the coat proteins senses the local changes in lipid packing that accompany membrane bending during vesiculation, and thus acts as a timer for coat ...

Quantum Sensing of Curvature [PDF]

International Journal of Theoretical Physics, 2019
We address the problem of sensing the curvature of a manifold by performing measurements on a particle constrained to the manifold itself. In particular, we consider situations where the dynamics of the particle is quantum mechanical and the manifold is a surface embedded in the three-dimensional Euclidean space. We exploit ideas and tools from quantum

Sensing Membrane Curvature in Macroautophagy [PDF]

Journal of Molecular Biology, 2017
In response to intracellular stress events ranging from starvation to pathogen invasion, the cell activates one or more forms of macroautophagy. The key event in these related pathways is the de novo formation of a new organelle called the autophagosome, which either surrounds and sequesters random portions of the cytoplasm or selectively targets ...
