It must generate or adapt to plasma membrane curvature to facilitate diverse functions such as cell division, migration, and phagocytosis. Due to the complex molecular makeup of the actin cortex, it remains unclear whether actin networks are inherently able to sense and generate membrane curvature, or whether they rely on their diverse binding partners to accomplish this. Here, we show that curvature sensing is an inherent capability of branched actin networks nucleated by Arp2/3 and VCA. We develop a robust method to encapsulate actin inside giant unilamellar vesicles (GUVs) and assemble an actin cortex at the inner surface of the GUV membrane. We show that actin forms a uniform and thin cortical layer when present at high concentration and distinct patches associated with negative membrane curvature at low concentration. Serendipitously, we find that the GUV production method also produces dumbbell-shaped GUVs, which we explain using mathematical modeling in terms of membrane hemifusion of nested GUVs. We find that branched actin networks preferentially assemble at the neck of the dumbbells, which possess a micrometer-range convex curvature comparable with the curvature of the actin patches found in spherical GUVs. Minimal branched actin networks can thus sense membrane curvature, which may help mammalian cells to robustly recruit actin to curved membranes to facilitate diverse cellular functions such as cytokinesis and migration."}],"day":"06","doi":"10.1016/j.bpj.2023.02.018","external_id":{"isi":["001016792600001"],"pmid":["36806830"]},"isi":1,"citation":{"ista":"Baldauf L, Frey FF, Arribas Perez M, Idema T, Koenderink GH. 2023.

Based on a biophysical simulation model for cell migration, we show that the\r\nbehavioral changes upon disruption of these junctions can be explained by reduced repulsive\r\nexcluded volume interactions between cells.

Although such interactions can be modeled at different levels of coarse graining, in vitro experimental data have been quantitatively described by minimal models that describe FG Nups as cohesive homogeneous polymers and NTRs as uniformly cohesive spheres, in which the heterogeneous effects have been smeared out. By definition, these minimal models do not account for the explicit heterogeneities in FG Nup sequences, essentially a string of cohesive and noncohesive polymer units, and at the NTR surface. Here, we develop computational and analytical models that do take into account such heterogeneity in a minimal fashion and compare them with experimental data on single-molecule interactions between FG Nups and NTRs. Overall, we find that the heterogeneous nature of FG Nups and NTRs does play a role in determining equilibrium binding properties but is of much greater significance when it comes to unbinding and binding kinetics. Using our models, we predict how binding equilibria and kinetics depend on the distribution of cohesive blocks in the FG Nup sequences and of the binding pockets at the NTR surface, with multivalency playing a key role. Finally, we observe that single-molecule binding kinetics has a rather minor influence on the diffusion of NTRs in polymer melts consisting of FG-Nup-like sequences.","lang":"eng"}],"doi":"10.1016/j.bpj.2021.01.039","day":"19","extern":"1","volume":120,"author":[{"full_name":"Davis, Luke K.","first_name":"Luke K.","last_name":"Davis"},{"first_name":"Anđela","last_name":"Šarić","orcid":"0000-0002-7854-2139","full_name":"Šarić, Anđela","id":"bf63d406-f056-11eb-b41d-f263a6566d8b"},{"full_name":"Hoogenboom, Bart W.","first_name":"Bart W.","last_name":"Hoogenboom"},{"full_name":"Zilman, Anton","first_name":"Anton","last_name":"Zilman"}],"issue":"9","_id":"10338","pmid":1,"scopus_import":"1","title":"Physical modeling of multivalent interactions in the nuclear pore complex","intvolume":"       120","publication_status":"published","date_created":"2021-11-25T15:36:36Z","article_processing_charge":"No","page":"1565-1577","quality_controlled":"1","article_type":"original","publisher":"Elsevier","date_published":"2021-02-19T00:00:00Z","type":"journal_article","oa":1,"publication_identifier":{"issn":["0006-3495"]},"status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","main_file_link":[{"url":"https://doi.org/10.1101/2020.10.01.322156","open_access":"1"}],"publication":"Biophysical Journal","month":"02","oa_version":"Preprint","language":[{"iso":"eng"}],"keyword":["biophysics"]},{"publication_identifier":{"issn":["0006-3495"]},"oa":1,"type":"journal_article","date_published":"2021-01-16T00:00:00Z","main_file_link":[{"open_access":"1","url":"https://doi.org/10.1101/2020.07.28.224741"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","status":"public","oa_version":"Preprint","month":"01","publication":"Biophysical Journal","keyword":["biophysics"],"language":[{"iso":"eng"}],"day":"16","doi":"10.1016/j.bpj.2020.12.028","abstract":[{"text":"The cell membrane is an inhomogeneous system composed of phospholipids, sterols, carbohydrates, and proteins that can be directly attached to underlying cytoskeleton. The protein linkers between the membrane and the cytoskeleton are believed to have a profound effect on the mechanical properties of the cell membrane and its ability to reshape. Here, we investigate the role of membrane-cortex linkers on the extrusion of membrane tubes using computer simulations and experiments. In simulations, we find that the force for tube extrusion has a nonlinear dependence on the density of membrane-cortex attachments: at a range of low and intermediate linker densities, the force is not significantly influenced by the presence of the membrane-cortex attachments and resembles that of the bare membrane. For large concentrations of linkers, however, the force substantially increases compared with the bare membrane. In both cases, the linkers provided membrane tubes with increased stability against coalescence. We then pulled tubes from HEK cells using optical tweezers for varying expression levels of the membrane-cortex attachment protein Ezrin. In line with simulations, we observed that overexpression of Ezrin led to an increased extrusion force, while Ezrin depletion had a negligible effect on the force. Our results shed light on the importance of local protein rearrangements for membrane reshaping at nanoscopic scales.","lang":"eng"}],"citation":{"apa":"Paraschiv, A., Lagny, T. J., Campos, C.

Morphogenesis involves an interplay between several factors, ranging from the gene regulatory networks determining cell fate and differentiation to the mechanical processes underlying cell and tissue shape changes. Thus, the study of morphogenesis has historically been based on multidisciplinary approaches at the interface of biology with physics and mathematics. Recent technological advances have further improved our ability to study morphogenesis by bridging the gap between the genetic and biophysical factors through the development of new tools for visualizing, analyzing, and perturbing these factors and their biochemical intermediaries. Here, we review how a combination of genetic, microscopic, biophysical, and biochemical approaches has aided our attempts to understand morphogenesis and discuss potential approaches that may be beneficial to such an inquiry in the future."}],"date_updated":"2023-08-14T13:05:13Z","year":"2021","citation":{"ista":"Mishra N, Heisenberg C-PJ. 2021.

Collagen type I molecules are a crucial component of the extracellular matrix, where they self-assemble into fibrils of well-defined axial striped patterns. This striped fibrillar pattern is preserved across the animal kingdom and is important for the determination of cell phenotype, cell adhesion, and tissue regulation and signaling. The understanding of the physical processes that determine such a robust morphology of self-assembled collagen fibrils is currently almost completely missing. Here, we develop a minimal coarse-grained computational model to identify the physical principles of the assembly of collagen-mimetic molecules. We find that screened electrostatic interactions can drive the formation of collagen-like filaments of well-defined striped morphologies. The fibril axial pattern is determined solely by the distribution of charges on the molecule and is robust to the changes in protein concentration, monomer rigidity, and environmental conditions. We show that the striped fibrillar pattern cannot be easily predicted from the interactions between two monomers but is an emergent result of multibody interactions. Our results can help address collagen remodeling in diseases and aging and guide the design of collagen scaffolds for biotechnological applications.","lang":"eng"}],"doi":"10.1016/j.bpj.2020.09.013","day":"23","extern":"1","acknowledgement":"We thank Melinda Duer, Patrick Mesquida, Lucy Colwell, Lucie Liu, Daan Frenkel, and Ivan Palaia for helpful discussions.

We make use of such well-described regulatory systems to explore how the molecular mechanisms of protein-protein and protein-DNA interactions shape the dynamics and evolution of gene regulation. \r\n\r\ni) We uncover how the biophysics of protein-DNA binding determines the potential of regulatory networks to evolve and adapt, which can be captured using a simple mathematical model. \r\nii) The evolution of regulatory connections can lead to a significant amount of crosstalk between binding proteins. We explore the effect of crosstalk on gene expression from a target promoter, which seems to be modulated through binding competition at non-specific DNA sites. \r\niii) We investigate how the very same biophysical characteristics as in i) can generate significant fitness costs for cells through global crosstalk, meaning non-specific DNA binding across the genomic background. \r\niv) Binding competition between proteins at a target promoter is a prevailing regulatory feature due to the prevalence of co-regulation at bacterial promoters. However, the dynamics of these systems are not always straightforward to determine even if the molecular mechanisms of regulation are known. A detailed model of the biophysical interactions reveals that interference between the regulatory proteins can constitute a new, generic form of system memory that records the history of the input signals at the promoter. \r\n\r\nWe demonstrate how the biophysics of protein-DNA binding can be harnessed to investigate the principles that shape and ultimately limit cellular gene regulation. These results provide a basis for studies of higher-level functionality, which arises from the underlying regulation.   \r\n"}]},{"intvolume":"       113","title":"Mitochondrial ADP/ATP carrier in dodecylphosphocholine binds cardiolipins with non-native affinity","month":"12","date_created":"2020-09-18T10:05:54Z","article_processing_charge":"No","oa_version":"None","publication_status":"published","issue":"11","author":[{"full_name":"Dehez, François","first_name":"François","last_name":"Dehez"},{"full_name":"Schanda, Paul","orcid":"0000-0002-9350-7606","last_name":"Schanda","first_name":"Paul","id":"7B541462-FAF6-11E9-A490-E8DFE5697425"},{"first_name":"Martin S.","last_name":"King","full_name":"King, Martin S."},{"full_name":"Kunji, Edmund R.S.","first_name":"Edmund R.S.","last_name":"Kunji"},{"last_name":"Chipot","first_name":"Christophe","full_name":"Chipot, Christophe"}],"_id":"8444","publication":"Biophysical Journal","article_type":"original","publisher":"Elsevier","keyword":["Biophysics"],"language":[{"iso":"eng"}],"quality_controlled":"1","page":"2311-2315","abstract":[{"lang":"eng","text":"Biophysical investigation of membrane proteins generally requires their extraction from native sources using detergents, a step that can lead, possibly irreversibly, to protein denaturation. The propensity of dodecylphosphocholine (DPC), a detergent widely utilized in NMR studies of membrane proteins, to distort their structure has been the subject of much controversy. It has been recently proposed that the binding specificity of the yeast mitochondrial ADP/ATP carrier (yAAC3) toward cardiolipins is preserved in DPC, thereby suggesting that DPC is a suitable environment in which to study membrane proteins. In this communication, we used all-atom molecular dynamics simulations to investigate the specific binding of cardiolipins to yAAC3. Our data demonstrate that the interaction interface observed in a native-like environment differs markedly from that inferred from an NMR investigation in DPC, implying that in this detergent, the protein structure is distorted. We further investigated yAAC3 solubilized in DPC and in the milder dodecylmaltoside with thermal-shift assays. The loss of thermal transition observed in DPC confirms that the protein is no longer properly folded in this environment."}],"day":"05","publication_identifier":{"issn":["0006-3495"]},"doi":"10.1016/j.bpj.2017.09.019","type":"journal_article","date_published":"2017-12-05T00:00:00Z","citation":{"mla":"Dehez, François, et al. “Mitochondrial ADP/ATP Carrier in Dodecylphosphocholine Binds Cardiolipins with Non-Native Affinity.” <i>Biophysical Journal</i>, vol. 113, no. 11, Elsevier, 2017, pp. 2311–15, doi:<a href=\"https://doi.org/10.1016/j.bpj.2017.09.019\">10.1016/j.bpj.2017.09.019</a>.","short":"F.

The apparatus is simple to build, inexpensive, and can be used without any hardware modification on any type of liquid-state NMR spectrometer.

We reimagined the successful DNA origami design principle using a set of custom staple proteins to fold a double-stranded DNA template into a user-defined shape. Each staple protein recognizes two distinct double-helical DNA sequences and can carry additional functionalities. The staple proteins we present here are based on the transcription activator-like (TAL) effector proteins. Due to their repetitive structure these proteins offer a unique programmability that enables us to construct numerous staple proteins targeting any desired DNA sequence. Our approach is general, meaning that many different objects may be created using the same set of rules, and it is modular, because components can be modified or exchanged individually. We present rules for constructing megadalton-scale DNA-protein hybrid nanostructures; introduce important structural motifs, such as curvature, corners, and vertices; describe principles for creating multi-layer DNA-protein objects with enhanced rigidity; and demonstrate the possibility to combine our DNA-protein hybrid origami with conventional DNA nanotechnology. Since all components can be encoded genetically, our structures should be amenable to biotechnological mass-production. Moreover, since the target objects can self-assemble at room temperature in near-physiological buffer, our hybrid origami may also provide an attractive method to realize positioning and scaffolding tasks in vivo. We expect our method to find application both in scaffolding protein functionalities and in manipulating the spatial arrangement of genomic DNA.","lang":"eng"}],"volume":112,"extern":"1"},{"extern":"1","volume":112,"doi":"10.1016/j.bpj.2016.11.2123","day":"03","date_updated":"2021-11-03T10:02:45Z","citation":{"ama":"Vahid Belarghou A, Šarić A, Idema T.

Averaging of the dipolar coupling reports on motions on time scales up to the inverse of the coupling constant, in our case tens of microseconds. Combining dipolar-coupling derived order parameters that characterize the amplitudes of the motion with relaxation data leads to a more precise characterization of the dynamical parameters and helps to disentangle the amplitudes and the time scales of the motional processes, which impact relaxation rates in a highly correlated way. Here. we describe and characterize an improved experimental protocol – based on REDOR – to measure these couplings in perdeuterated proteins with a reduced sensitivity to experimental missettings. Because such effects are presently the dominant source of systematic errors in experimental dipolar-coupling measurements, these compensated experiments should help to significantly improve the precision of such data. A detailed comparison with other commonly used pulse sequences (T-MREV, phase-inverted CP,R18 5/2, and R18 7/1) is provided."}],"doi":"10.1016/j.jmr.2011.03.015","day":"01","publication_identifier":{"issn":["1090-7807"]},"language":[{"iso":"eng"}],"keyword":["Nuclear and High Energy Physics","Biophysics","Biochemistry","Condensed Matter Physics"],"page":"246-259","quality_controlled":"1","article_type":"original","publisher":"Elsevier","author":[{"id":"7B541462-FAF6-11E9-A490-E8DFE5697425","full_name":"Schanda, Paul","orcid":"0000-0002-9350-7606","last_name":"Schanda","first_name":"Paul"},{"last_name":"Meier","first_name":"Beat H.","full_name":"Meier, Beat H."},{"last_name":"Ernst","first_name":"Matthias","full_name":"Ernst, Matthias"}],"issue":"2","publication":"Journal of Magnetic Resonance","_id":"8469","month":"06","title":"Accurate measurement of one-bond H–X heteronuclear dipolar couplings in MAS solid-state NMR","intvolume":"       210","publication_status":"published","oa_version":"None","date_created":"2020-09-18T10:10:50Z","article_processing_charge":"No"},{"issue":"2","author":[{"last_name":"Kern","first_name":"Thomas","full_name":"Kern, Thomas"},{"id":"7B541462-FAF6-11E9-A490-E8DFE5697425","orcid":"0000-0002-9350-7606","full_name":"Schanda, Paul","first_name":"Paul","last_name":"Schanda"},{"full_name":"Brutscher, Bernhard","first_name":"Bernhard","last_name":"Brutscher"}],"publication":"Journal of Magnetic Resonance","_id":"8482","intvolume":"       190","month":"02","title":"Sensitivity-enhanced IPAP-SOFAST-HMQC for fast-pulsing 2D NMR with reduced radiofrequency load","date_created":"2020-09-18T10:12:46Z","article_processing_charge":"No","publication_status":"published","oa_version":"None","keyword":["Nuclear and High Energy Physics","Biophysics","Biochemistry","Condensed Matter Physics"],"language":[{"iso":"eng"}],"quality_controlled":"1","page":"333-338","article_type":"letter_note","publisher":"Elsevier","type":"journal_article","date_published":"2008-02-01T00:00:00Z","year":"2008","citation":{"apa":"Kern, T., Schanda, P., &#38; Brutscher, B.

To achieve the highest possible sensitivity, SOFAST-HMQC experiments are preferably performed on high-field NMR spectrometers equipped with cryogenically cooled probes. The duty cycle of over 80% in fast-pulsing SOFAST-HMQC experiments, however, may cause problems when using a cryogenic probe. Here we introduce SE-IPAP-SOFAST-HMQC, a new pulse sequence that provides comparable sensitivity to standard SOFAST-HMQC, while avoiding heteronuclear decoupling during 1H detection, and thus significantly reducing the radiofrequency load of the probe during the experiment. The experiment is also attractive for fast and sensitive measurement of heteronuclear one-bond spin coupling constants."}],"day":"01","publication_identifier":{"issn":["1090-7807"]},"doi":"10.1016/j.jmr.2007.11.015","status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","extern":"1","volume":190},{"language":[{"iso":"eng"}],"keyword":["Nuclear and High Energy Physics","Biophysics","Biochemistry","Condensed Matter Physics"],"page":"334-339","article_type":"original","publisher":"Elsevier","author":[{"last_name":"Schanda","first_name":"Paul","full_name":"Schanda, Paul","orcid":"0000-0002-9350-7606","id":"7B541462-FAF6-11E9-A490-E8DFE5697425"},{"last_name":"Brutscher","first_name":"Bernhard","full_name":"Brutscher, Bernhard"}],"issue":"2","_id":"8490","publication":"Journal of Magnetic Resonance","title":"Hadamard frequency-encoded SOFAST-HMQC for ultrafast two-dimensional protein NMR","month":"02","intvolume":"       178","oa_version":"None","publication_status":"published","article_processing_charge":"No","date_created":"2020-09-18T10:13:51Z","extern":"1","status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","volume":178,"date_published":"2006-02-01T00:00:00Z","type":"journal_article","date_updated":"2021-01-12T08:19:38Z","citation":{"chicago":"Schanda, Paul, and Bernhard Brutscher. “Hadamard Frequency-Encoded SOFAST-HMQC for Ultrafast Two-Dimensional Protein NMR.” <i>Journal of Magnetic Resonance</i>.
