    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.

    Functional instability allows access to DNA in longer transcription Activator-Like effector (TALE) arrays

    Kathryn Geiger-Schuller et al.
    Single molecule DNA-binding trajectories and deterministic modeling analyses demonstrate a functional role for high energy partly folded states in Transcription Activator-Like Effectors that could improve future TALEN design.

    DNA sequence encodes the position of DNA supercoils

    Sung Hyun Kim et al.
    Single-molecule experiments reveal that plectonemic supercoils occupy specific positions on DNA and a physical model relates this to the intrinsic curvature, providing an insight into how supercoiling organizes the genome.

    Nucleophosmin integrates within the nucleolus via multi-modal interactions with proteins displaying R-rich linear motifs and rRNA

    Diana M Mitrea et al.
    Nucleolar protein localization involves the phase separation within the nucleolar matrix via three types of multivalent features: acidic tracts, nucleic acid binding domains and arginine-rich low complexity sequences.

    Characterization of the kinetic cycle of an ABC transporter by single-molecule and cryo-EM analyses

    Ling Wang et al.
    The conformational dynamics of multidrug resistance protein 1 (MRP1) are tracked in real time by single-molecule fluorescence resonance energy transfer experiments, which elucidate the rate-limiting mechanism of MRP1's transport cycle.

    Selective dendritic localization of mRNA in Drosophila mushroom body output neurons

    Jessica Mitchell et al.
    Specific mRNAs localize to the dendrites of Drosophila mushroom body output neurons.

    Absolute quantification of cohesin, CTCF and their regulators in human cells

    Johann Holzmann et al.
    Absolute quantification of cohesin, CTCF, NIPBL, WAPL and sororin in HeLa cells implies that some genomic cohesin and CTCF enrichment sites are unoccupied at any one time.

    Transcription factor clusters regulate genes in eukaryotic cells

    Adam JM Wollman et al.
    Transcription factors form clusters independently of the presence of DNA, which regulate target genes as opposed to individual monomers, addressing a longstanding question of how transcription factors can find gene targets so quickly.

    Single-molecule FRET unveils induced-fit mechanism for substrate selectivity in flap endonuclease 1

    Fahad Rashid et al.
    Structure specific nucleases that act in DNA replication, repair and recombination actively mold their DNA while transforming their own structure to achieve precise cleavage of their cognate DNA and avoid the deleterious cleavage of noncognate DNA.

    The Wg and Dpp morphogens regulate gene expression by modulating the frequency of transcriptional bursts

    Rachael Bakker et al.
    Experimental results in Drosophila support a model in which gene expression is fundamentally controlled by morphogens tuning the same transcription parameter for genes that are expressed in highly diverse patterns.
