Physical limits to membrane curvature sensing by a single protein [PDF]
Phys. Rev. E 108, 064407 (2023), 2022 Membrane curvature sensing is essential for a diverse range of biological processes. Recent experiments have revealed that a single nanometer-sized septin protein can distinguish between membrane-coated glass beads of one micron and three micron diameters, even though the septin is orders of magnitude smaller than the beads.

Super-Resolution Imaging Approaches for Quantifying F-Actin in Immune Cells
Frontiers in Cell and Developmental Biology, 2021 Immune cells comprise a diverse set of cells that undergo a complex array of biological processes that must be tightly regulated. A key component of cellular machinery that achieves this is the cytoskeleton.

In vitro reconstitution of substrate S-acylation by the zDHHC family of protein acyltransferases
Open Biology, 2022 Protein S-acylation, more commonly known as protein palmitoylation, is a biological process defined by the covalent attachment of long chain fatty acids onto cysteine residues of a protein, effectively altering the local hydrophobicity and influencing ...

Membrane shape deformation induced by curvature-inducing proteins consisting of chiral crescent binding and intrinsically disordered domains [PDF]
J. Chem. Phys. 157, 034901 (2022), 2022 Curvature-inducing proteins containing a Bin/Amphiphysin/Rvs domain often have intrinsically disordered domains. Recent experiments have shown that these disordered chains enhance curvature sensing and generation. Here, we report on the modification of protein-membrane interactions by disordered chains using meshless membrane simulations.

Rampant exchange of the structure and function of extramembrane domains between membrane and water soluble proteins. [PDF]
, 2013 Of the membrane proteins of known structure, we found that a remarkable 67% of the water soluble domains are structurally similar to water soluble proteins of known structure. Moreover, 41% of known water soluble protein structures share a domain with an

Binding of anisotropic curvature-inducing proteins onto membrane tubes [PDF]
Soft Matter 18, 3384-3394 (2022), 2022 Bin/Amphiphysin/Rvs superfamily proteins and other curvature-inducing proteins have anisotropic shapes and anisotropically bend biomembrane. Here, we report how the anisotropic proteins bind the membrane tube and are orientationally ordered using mean-field theory including an orientation-dependent excluded volume.

The Bacterial Photosynthetic Reaction Center as a Model for Membrane Proteins [PDF]
, 1989 Membrane proteins participate in many fundamental cellular processes. Until recently, an understanding of the function and properties of membrane proteins was hampered by an absence of structural information at the atomic level.

Evaluation of four different strategies to characterize plasma membrane proteins from banana roots [PDF]
, 2015 Plasma membrane proteins constitute a very important class of proteins. They are involved in the transmission of external signals to the interior of the cell and selective transport of water, nutrients and ions across the plasma membrane.
