Revealing the Effects of Nanoscale Membrane Curvature on Lipid Mobility

Membranes, 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

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 ...

Arf1 and membrane curvature cooperate to recruit Arfaptin2 to liposomes. [PDF]

PLoS ONE, 2013
Arfaptin2 contains a Bin/Amphiphysin/Rvs (BAR) domain and directly interacts with proteins of the Arf/Arl family in their active GTP-bound state. It has been proposed that BAR domains are able to sense membrane curvature and to induce membrane tubulation.

Modeling curvature-dependent subcellular localization of the small sporulation protein SpoVM in Bacillus subtilis. [PDF]

PLoS ONE, 2015
Recent in vivo experiments suggest that in the bacterium, Bacillus subtilis, the cue for the localization of the small sporulation protein, SpoVM, an essential factor in spore coat formation, is curvature of the bacterial plasma membrane.

Curvature-Mediated Pair Interactions of Soft Nanoparticles Adhered to a Cell Membrane

, 2021
The curvature-mediated interactions by cell membranes are crucial in many biological processes. We systematically studied the curvature-mediated wrapping of soft nanoparticles (NPs) by a tensionless membrane and the underlying pair interactions between ...

Comparative Study of Curvature Sensing Mediated by F-BAR and an Intrinsically Disordered Region of FBP17

iScience, 2020
Summary: Membrane curvature has emerged as an intriguing physical principle underlying biological signaling and membrane trafficking. The CIP4/FBP17/Toca-1 F-BAR subfamily is unique in the BAR family because its structurally folded F-BAR domain does not ...
