    Distinct mechanisms regulating mechanical force-induced Ca2+ signals at the plasma membrane and the ER in human MSCs

    Tae-Jin Kim, Chirlmin Joo ... Yingxiao Wang
    Deep penetration and transmission of mechanical force to regulate ER functions depends on not only the passive cytoskeletal support, but also the active actomyosin contractility, which is dispensable for mechanotransduction at the plasma membrane.

    Synergy between RecBCD subunits is essential for efficient DNA unwinding

    Rani Zananiri, Omri Malik ... Ariel Kaplan
    A new optical tweezers assay sheds light on the mechanism of cooperation and force generation by the subunits of RecBCD, critical for the repair of double strand breaks in bacteria.

    3D single cell migration driven by temporal correlation between oscillating force dipoles

    Amélie Luise Godeau, Marco Leoni ... Daniel Riveline
    A phase shift between local contractions drives 3D cell motility in experiments and in model or how a finite area in the dipole-quadrupole space explains cell motion with zero total force.

    Direct measurement of conformational strain energy in protofilaments curling outward from disassembling microtubule tips

    Jonathan W Driver, Elisabeth A Geyer ... Charles L Asbury
    The protofilaments that curl outward from a disassembling microtubule tip carry a large amount of strain energy and they can drive movement with an efficiency similar to conventional motor proteins.

    Munc18-1 catalyzes neuronal SNARE assembly by templating SNARE association

    Junyi Jiao, Mengze He ... Yongli Zhang
    Sec1/Munc18-family proteins chaperone SNARE assembly via a common templating mechanism.

    Single-molecule observation of DNA compaction by meiotic protein SYCP3

    Johanna L Syrjänen, Iddo Heller ... Luca Pellegrini
    Building on previous work (Syrjänen, Pellegrini, & Davies, 2014), it is shown that SYCP3 contributes to the architecture of meiotic chromosomes through local bridging interactions that result in large-scale compaction of the chromosome axis.

    Functional role of the type 1 pilus rod structure in mediating host-pathogen interactions

    Caitlin N Spaulding, Henry Louis Schreiber IV ... Edward H Egelman
    The helical rod structure and dynamic spring-like properties of the type 1 pilus are evolutionarily fine-tuned for functioning in host-pathogen interactions during urinary tract infection and gut colonization.

    Direct measurement of the mechanical work during translocation by the ribosome

    Tingting Liu, Ariel Kaplan ... Carlos J Bustamante
    ‘Optical tweezers’ measurements of single ribosomes and single mRNA molecules show that the translation rate depends exponentially on the applied force, and suggests that the ribosome functions as a Brownian ratchet.

    ATP binding facilitates target search of SWR1 chromatin remodeler by promoting one-dimensional diffusion on DNA

    Claudia C Carcamo, Matthew F Poyton ... Taekjip Ha
    In vitro single-particle tracking reveals that ATP binding increases the one-dimensional diffusion of yeast chromatin remodeler SWR1 on DNA stretched between optical tweezers and diffusion is confined by protein roadblocks and nucleosomes.

    Dynamic 1D search and processive nucleosome translocations by RSC and ISW2 chromatin remodelers

    Jee Min Kim, Claudia C Carcamo ... Carl Wu
    Single-particle imaging of RSC and ISW2 chromatin remodelers on DNA stretched between dual optical tweezers reveals distinctive 1D diffusion and opposing push–pull nucleosome translocation on engagement with sparse nucleosome arrays.
