Distribution of randomly diffusing particles in inhomogeneous media
Yiwei Li, Osman Kahraman, Christoph A. Haselwandter
Diffusion can be conceptualized, at microscopic scales, as the random hopping of particles between neighboring lattice sites. In the case of diffusion in inhomogeneous media, disti…
Stochastic lattice model of synaptic membrane protein domains
Yiwei Li, Osman Kahraman, Christoph A. Haselwandter
Neurotransmitter receptor molecules, concentrated in synaptic membrane domains along with scaffolds and other kinds of proteins, are crucial for signal transmission across chemical…
Controlling the shape of membrane protein polyhedra
Di Li, Osman Kahraman, Christoph A. Haselwandter
Membrane proteins and lipids can self-assemble into membrane protein polyhedral nanoparticles (MPPNs). MPPNs have a closed spherical surface and a polyhedral protein arrangement, a…
Thermodynamic competition between membrane protein oligomeric states
Osman Kahraman, Christoph A. Haselwandter
Self-assembly of protein monomers into distinct membrane protein oligomers provides a general mechanism for diversity in the molecular architectures, and resulting biological funct…
Stochastic single-molecule dynamics of synaptic membrane protein domains
Osman Kahraman, Yiwei Li, Christoph A. Haselwandter
Motivated by single-molecule experiments on synaptic membrane protein domains, we use a stochastic lattice model to study protein reaction and diffusion processes in crowded membra…
Symmetry and size of membrane protein polyhedral nanoparticles
Di Li, Osman Kahraman, Christoph A. Haselwandter
In recent experiments [T. Basta et al., Proc. Natl. Acad. Sci. U.S.A. 111, 670 (2014)] lipids and membrane proteins were observed to self-assemble into membrane protein polyhedral…
Bilayer-thickness-mediated interactions between integral membrane proteins
Osman Kahraman, Peter D. Koch, William S. Klug +1
Hydrophobic thickness mismatch between integral membrane proteins and the surrounding lipid bilayer can produce lipid bilayer thickness deformations. Experiment and theory have sho…
Architecture and Function of Mechanosensitive Membrane Protein Lattices
Osman Kahraman, Peter D. Koch, William S. Klug +1
Experiments have revealed that membrane proteins can form two-dimensional clusters with regular translational and orientational protein arrangements, which may allow cells to modul…
Signatures of protein structure in the cooperative gating of mechanosensitive ion channels
Osman Kahraman, William S. Klug, Christoph A. Haselwandter
Membrane proteins deform the surrounding lipid bilayer, which can lead to membrane-mediated interactions between neighboring proteins. Using the mechanosensitive channel of large c…
Confotronic Dynamics of Tubular Lattices
Osman Kahraman, Hervé Mohrbach, Martin Michael Müller +1
Tubular lattices are ubiquitous in nature and technology. Microtubules and nanotubes of all kinds act as important pillars of biological cells and the man-made nano-world. We show…
Dipoles in thin sheets
Jemal Guven, J. A. Hanna, Osman Kahraman +1
A flat elastic sheet may contain pointlike conical singularities that carry a metrical "charge" of Gaussian curvature. Adding such elementary defects to a sheet allows one to make…
Morphogenesis of membrane invaginations in spherical confinement
Osman Kahraman, Norbert Stoop, Martin Michael Mueller
We study the morphology of a fluid membrane in spherical confinement. When the area of the membrane is slightly larger than the area of the outer container, a single axisymmetric i…
