    Doublecortin engages the microtubule lattice through a cooperative binding mode involving its C-terminal domain

    Atefeh Rafiei, Sofía Cruz Tetlalmatzi ... David C Schriemer
    Doublecortin activates its C-terminal domain when its N-terminal domain engages the microtubule lattice, leading to self-associations that explain the stabilizing effect of Doublecortin in neuronal migration.

    Seipin transmembrane segments critically function in triglyceride nucleation and lipid droplet budding from the membrane

    Siyoung Kim, Jeeyun Chung ... Gregory A Voth
    The functions of seipin in triacylglycerol nucleation and lipid droplet maturation are studied with all-atom and coarse-grained simulations along with cell experiments, providing a novel model for lipid droplet formation.

    Rate-limiting transport of positively charged arginine residues through the Sec-machinery is integral to the mechanism of protein secretion

    William J Allen, Robin A Corey ... Ian Collinson
    The time it takes to secrete a protein is dominated by diffusion of positively charged arginines through the channel across the membrane, but lysines avoid this problem as they are neutralised before transport.

    Ligand binding remodels protein side-chain conformational heterogeneity

    Stephanie A Wankowicz, Saulo H de Oliveira ... James S Fraser
    Protein conformational heterogeneity changes upon ligand binding are influenced by ligand properties and can modulate the free energy of binding.

    Von Willebrand factor A1 domain stability and affinity for GPIbα are differentially regulated by its O-glycosylated N- and C-linker

    Klaus Bonazza, Roxana E Iacob ... Timothy A Springer
    Both the polypeptide and attached O-glycans N-terminal to the A1 domain in von Willebrand factor lower its affinity for its ligand GPIbα on platelets, its stability, and structural dynamics and decrease population of a high-affinity, intermediate state in unfolding.

    De novo-designed transmembrane domains tune engineered receptor functions

    Assaf Elazar, Nicholas J Chandler ... Sarel J Fleishman
    Designer transmembrane peptides precisely control chimeric antigen receptor signaling strength and are insulated from undesired interactions with endogenous receptors.

    Cryo-EM structure of the human somatostatin receptor 2 complex with its agonist somatostatin delineates the ligand-binding specificity

    Yunseok Heo, Eojin Yoon ... Weontae Lee
    The atomic resolution cryo-EM structure of somatostatin receptor 2 (SSTR2) provides insights into the mechanism by which SSTRs recognize their ligands and will serve as a platform to develop selective agonists and therapeutics.
