    C-mannosylation supports folding and enhances stability of thrombospondin repeats

    Aleksandra Shcherbakova et al.
    C-mannosylation supports native folding of thrombospondin type 1 repeats in the endoplasmic reticulum and stabilizes the folded proteins by modulating the dynamics of the tryptophan-arginine ladder.

    Routine single particle CryoEM sample and grid characterization by tomography

    Alex J Noble et al.
    Fiducial-less tomography on single particle cryoEM samples reveals that most particles are adsorbed to the air-water interface and allows for researchers to diagnose and solve sample, grid, ice thickness, collection, and processing issues.

    Small molecule-mediated refolding and activation of myosin motor function

    Michael B Radke et al.
    The small molecule EMD 57033 is one of a new class of pharmacological chaperones that stabilize, enhance the activity of, and correct stress-induced misfolding of myosin proteins.

    Expansion microscopy of C. elegans

    Chih-Chieh (Jay) Yu et al.
    Fixed, intact animals of C. elegans can be physically expanded with high isotropy, to enable super-resolved imaging of general proteins and nucleic acids throughout the organism, on conventional microscopes.

    Narrow equilibrium window for complex coacervation of tau and RNA under cellular conditions

    Yanxian Lin et al.
    Liquid-liquid phase separation of tau is demonstrated to be an equilibrium state, stable only within a narrow range near physiological conditions, and thus has the capacity to regulate biological processes.

    Cell-sized confinement controls generation and stability of a protein wave for spatiotemporal regulation in cells

    Shunshi Kohyama et al.
    A cell-sized fully confined space significantly controls the emergence and stability of a protein wave, resulting in intracellular spatiotemporal regulation driven by a reaction-diffusion mechanism.

    Monitoring site-specific conformational changes in real-time reveals a misfolding mechanism of the prion protein

    Ishita Sengupta, Jayant Udgaonkar
    Multi-site FRET measurements of moPrP oligomerization at low pH indicate that major conformational changes take place as monomers reversibly transform into large oligomers, which subsequently disassemble reversibly into small oligomers.
