    Single-molecule observation of DNA compaction by meiotic protein SYCP3

    Johanna L Syrjänen et al.
    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.

    Kinetics of HIV-1 capsid uncoating revealed by single-molecule analysis

    Chantal L Márquez et al.
    Disassembly of the HIV-1 capsid is a catastrophic process, whereby initiation and propagation can be controlled independently by molecules that bind to different features of the capsid lattice.

    Single-molecule visualization of fast polymerase turnover in the bacterial replisome

    Jacob S Lewis et al.
    The canonical model that the bacterial replisome tightly holds on to its polymerases is challenged by the visualization of rapid holoenzyme exchange, both in vitro and in vivo.

    Single-molecule analysis reveals self assembly and nanoscale segregation of two distinct cavin subcomplexes on caveolae

    Yann Gambin et al.
    New insights into the assembly and membrane interactions of the caveolar coat complex reveal the reversible association/dissociation of distinct subcomplexes onto the membrane, which differs from the assembly/disassembly of clathrin-coated pits.

    Single-molecule force spectroscopy of protein-membrane interactions

    Lu Ma et al.
    A high-resolution method to quantify interactions between lipid bilayers and single proteins under controlled load is presented and applied to key proteins involved in membrane fusion and formation and maintenance of membrane contact sites.

    Mapping translation 'hot-spots' in live cells by tracking single molecules of mRNA and ribosomes

    Zachary B Katz et al.
    A method that involves simultaneous tracking of individual mRNAs and their associated ribosomes can be used to determine when and where individual molecules get translated in living cells.

    Single-molecule tracking in live cells reveals distinct target-search strategies of transcription factors in the nucleus

    Ignacio Izeddin et al.
    While the transcription factor c-Myc explores the space in the nucleus in an unrestricted manner, the elongation factor P-TEFb's sampling of the nucleus is constrained to a complex domain with fractal characteristics.

    Single-molecule imaging of telomerase reverse transcriptase in human telomerase holoenzyme and minimal RNP complexes

    Robert Alexander Wu et al.
    New labeling approaches for single-molecule fluorescence microscopy detect the monomeric catalytic subunit of human telomerase within cellular holoenzyme and minimal active recombinant enzyme.

    Single molecule FRET reveals pore size and opening mechanism of a mechano-sensitive ion channel

    Yong Wang et al.
    Observation by single molecule FRET of MscL, a prokaryotic mechanosensitive channel, reveals that MscL opens via the helix-tilt model and its pore reaches 2.8 nm in diameter.

    Single molecule compression reveals intra-protein forces drive cytotoxin pore formation

    Daniel M Czajkowsky et al.
    Compressive force spectroscopy of single molecules reveals that intra-protein forces underlie the long-distance coordination of structural changes within a cytotoxin during pore formation.
