    Live-cell single-molecule tracking highlights requirements for stable Smc5/6 chromatin association in vivo

    Thomas J Etheridge et al.
    In vivo single-molecule imaging demonstrates that Smc5/6 chromatin association depends on ATP hydrolysis and dsDNA binding, requires Nse6 and is modulated by Brc1 after DNA damage.

    Homology sensing via non-linear amplification of sequence-dependent pausing by RecQ helicase

    Yeonee Seol et al.
    The rate of DNA unwinding by RecQ helicases is dramatically modulated by the DNA duplex stability in a geometry-dependent manner, providing an intrinsic mechanism for suppressing illegitimate recombination.

    Top-down machine learning approach for high-throughput single-molecule analysis

    David S White et al.
    A new analysis algorithm (DISC) enables accurate analysis of data from high-throughput single-molecule paradigms and reveals a non-cooperative binding mechanism of cyclic nucleotide-binding domains from HCN ion channels.

    Single molecule microscopy reveals key physical features of repair foci in living cells

    Judith Miné-Hattab et al.
    Upon DNA damage, Rad52 forms a membraneless sub-compartment where Rad52 molecules are highly dynamic and share properties with liquid-liquid phase-separated molecules, reflecting the existence of a liquid droplet around damaged DNA.

    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.

    Cellular encoding of Cy dyes for single-molecule imaging

    Lilia Leisle et al.
    Cyanine fluorophores are encoded as non-canonical amino acids to produce functional proteins in cell-free translation systems and live cells for single-molecule imaging.

    Single-molecule tracking of the transcription cycle by sub-second RNA detection

    Zhengjian Zhang et al.
    A new technique called fastFISH enables nearly real-time and stoichiometric detection of nascent RNA and the tracking of individual stages of transcription at the level of single-molecules.

    Resolving dual binding conformations of cellulosome cohesin-dockerin complexes using single-molecule force spectroscopy

    Markus A Jobst et al.
    A single-molecule approach is able to discriminate the redundant binding conformations of cellulosomal dockerin based on differences in their mechanical properties.

    Direct single molecule measurement of TCR triggering by agonist pMHC in living primary T cells

    Geoff P O'Donoghue et al.
    Quantitative observations of single-molecule binding between antigen and T cell receptor (TCR) in living primary T cells reveals unbinding kinetics, stoichiometry and signaling molecule recruitment, providing insights into the mechanisms of antigen recognition by the immune system.
