  text: The actin cortex is a complex cytoskeletal machinery that drives and responds
    to changes in cell shape. 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.

  text: Small GTPases play essential roles in the organization of eukaryotic cells.
    In recent years, it has become clear that their intracellular functions result
    from intricate biochemical networks of the GTPase and their regulators that dynamically
    bind to a membrane surface. Due to the inherent complexities of their interactions,
    however, revealing the underlying mechanisms of action is often difficult to achieve
    from in vivo studies. This review summarizes in vitro reconstitution approaches
    developed to obtain a better mechanistic understanding of how small GTPase activities
    are regulated in space and time.

  text: "Cell dispersion from a confined area is fundamental in a number of biological
    processes,\r\nincluding cancer metastasis. To date, a quantitative understanding
    of the interplay of single\r\ncell motility, cell proliferation, and intercellular
    contacts remains elusive. In particular, the role\r\nof E- and N-Cadherin junctions,
    central components of intercellular contacts, is still\r\ncontroversial. Combining
    theoretical modeling with in vitro observations, we investigate the\r\ncollective
    spreading behavior of colonies of human cancer cells (T24). The spreading of these\r\ncolonies
    is driven by stochastic single-cell migration with frequent transient cell-cell
    contacts.\r\nWe find that inhibition of E- and N-Cadherin junctions decreases
    colony spreading and average\r\nspreading velocities, without affecting the strength
    of correlations in spreading velocities of\r\nneighboring cells. 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. This suggests that in cancer cell migration,\r\ncadherin-based
    intercellular contacts sharpen cell boundaries leading to repulsive rather than\r\ncohesive
    interactions between cells, thereby promoting efficient cell spreading during
    collective\r\nmigration.\r\n"

  text: In the nuclear pore complex, intrinsically disordered proteins (FG Nups),
    along with their interactions with more globular proteins called nuclear transport
    receptors (NTRs), are vital to the selectivity of transport into and out of the
    cell nucleus. 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.

  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.'

  text: Multicellular organisms develop complex shapes from much simpler, single-celled
    zygotes through a process commonly called morphogenesis. 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.

  text: One of the most robust examples of self-assembly in living organisms is the
    formation of collagen architectures. 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.

  text: "Decades of studies have revealed the mechanisms of gene regulation in molecular
    detail. 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.

  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.

  text: We present an improved fast mixing device based on the rapid mixing of two
    solutions inside the NMR probe, as originally proposed by Hore and coworkers (J.
    Am. Chem. Soc. 125 (2003) 12484–12492). Such a device is important for off-equilibrium
    studies of molecular kinetics by multidimensional real-time NMR spectrsocopy.
    The novelty of this device is that it allows removing the injector from the NMR
    detection volume after mixing, and thus provides good magnetic field homogeneity
    independently of the initial sample volume placed in the NMR probe. The apparatus
    is simple to build, inexpensive, and can be used without any hardware modification
    on any type of liquid-state NMR spectrometer. We demonstrate the performance of
    our fast mixing device in terms of improved magnetic field homogeneity, and show
    an application to the study of protein folding and the structural characterization
    of transiently populated folding intermediates.

  text: Here we describe an approach to bottom-up fabrication with nanometer-precision
    that allows integrating the functional diversity of proteins in designed three-dimensional
    structural frameworks. 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.

  text: 'The crowded intracellular environment poses a formidable challenge to experimental
    and theoretical analyses of intracellular transport mechanisms. Our measurements
    of single-particle trajectories in cytoplasm and their random-walk interpretations
    elucidate two of these mechanisms: molecular diffusion in crowded environments
    and cytoskeletal transport along microtubules. We employed acousto-optic deflector
    microscopy to map out the three-dimensional trajectories of microspheres migrating
    in the cytosolic fraction of a cellular extract. Classical Brownian motion (BM),
    continuous time random walk, and fractional BM were alternatively used to represent
    these trajectories. The comparison of the experimental and numerical data demonstrates
    that cytoskeletal transport along microtubules and diffusion in the cytosolic
    fraction exhibit anomalous (nonFickian) behavior and posses statistically distinct
    signatures. Among the three random-walk models used, continuous time random walk
    provides the best representation of diffusion, whereas microtubular transport
    is accurately modeled with fractional BM.'

  text: The accurate experimental determination of dipolar-coupling constants for
    one-bond heteronuclear dipolar couplings in solids is a key for the quantification
    of the amplitudes of motional processes. 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.

  text: The SOFAST-HMQC experiment [P. Schanda, B. Brutscher, Very fast two-dimensional
    NMR spectroscopy for real-time investigation of dynamic events in proteins on
    the time scale of seconds, J. Am. Chem. Soc. 127 (2005) 8014–8015] allows recording
    two-dimensional correlation spectra of macromolecules such as proteins in only
    a few seconds acquisition time. 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.

  text: We demonstrate the feasibility of recording 1H–15N correlation spectra of
    proteins in only one second of acquisition time. The experiment combines recently
    proposed SOFAST-HMQC with Hadamard-type 15N frequency encoding. This allows site-resolved
    real-time NMR studies of kinetic processes in proteins with an increased time
    resolution. The sensitivity of the experiment is sufficient to be applicable to
    a wide range of molecular systems available at millimolar concentration on a high
    magnetic field spectrometer.
