    Noncovalent antibody catenation on a target surface greatly increases the antigen-binding avidity

    Jinyeop Song, Bo-Seong Jeong ... Byung-Ha Oh
    Genetically fusing weakly homodimerizing proteins to the C-terminus of IgG antibodies to induce reversible catenation on a target surface greatly enhances antigen-binding avidity, offering a promising approach for a range of antibody applications.

    Cannabidiol sensitizes TRPV2 channels to activation by 2-APB

    Aaron Gochman, Xiao-Feng Tan ... Andres Jara-Oseguera
    Cannabidiol is an ultra potent sensitizer for 2-APB responses in rTRPV2 and mTRPV3 channels but not in rTRPV1 through a mechanism that engages channel regions further from the cannabidiol binding site and the pore.

    High-resolution structures with bound Mn2+ and Cd2+ map the metal import pathway in an Nramp transporter

    Shamayeeta Ray, Samuel P Berry ... Rachelle Gaudet
    Structures of a transition metal transporter spanning the entire Mn2+ transport cycle reveal distinct coordination geometries and dynamic polar networks that enable Mn2+ import, and a Cd2+-bound structure helps explain how Cd2+ behaves differently as a substrate.

    A pH-dependent cluster of charges in a conserved cryptic pocket on flaviviral envelopes

    Lorena Zuzic, Jan K Marzinek ... Peter J Bond
    Benzene mapping simulations of envelope protein rafts from six different flaviviruses reveal a conserved cryptic site whose cluster of ionisable residues is likely responsible for orchestrating pH-dependent conformational changes during fusion, thereby representing an attractive target for antiviral development.

    Transmembrane protein CD69 acts as an S1PR1 agonist

    Hongwen Chen, Yu Qin ... Xiaochun Li
    Cryo-EM in combination with biochemistry, flow cytometry and fluorescence microscopy reveals the activation of S1PR1 by CD69, a type II membrane protein, in cis to induce receptor internalization and thereby disrupt cellular responsiveness to S1P gradients.

    Concurrent remodelling of nucleolar 60S subunit precursors by the Rea1 ATPase and Spb4 RNA helicase

    Valentin Mitterer, Matthias Thoms ... Roland Beckmann
    The RNA helicase Spb4 restructures rRNA helices H62/H63 and primes pre-ribosomal 60S intermediates for large-scale remodelling by the AAA-ATPase Rea1.
