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.

Amphipathic helices and membrane curvature [PDF]
FEBS Letters, 2009 Numerous data have been collected on lipid‐binding amphipathic helices involved in membrane‐remodeling machineries and vesicular transport. Here we describe how, with regard to lipid composition, the physicochemical features of some amphipathic helices explain their ability to recognize membrane curvature or to participate in membrane remodeling.

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.

Curvature dependence of BAR protein membrane association and dissociation kinetics
Scientific Reports, 2022 BAR (Bin/Amphiphysin/Rvs) domain containing proteins function as lipid bilayer benders and curvature sensors, and they contribute to membrane shaping involved in cell signaling and metabolism.

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

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

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

The role of traction in membrane curvature generation [PDF]
Molecular Biology of the Cell, 2017 Abstract Curvature of biological membranes can be generated by a variety of molecular mechanisms including protein scaffolding, compositional heterogeneity, and cytoskeletal forces. These mechanisms have the net effect of generating tractions (force per unit length) on the bilayer that are translated into distinct shapes of the membrane.

Communicative & 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.
