    Structural basis of TRPC4 regulation by calmodulin and pharmacological agents

    Deivanayagabarathy Vinayagam, Dennis Quentin ... Stefan Raunser
    Cryo-EM structures reveal how the canonical TRPC4 cation channel is regulated by calmodulin, and how it is modulated by pyridazinone-based inhibitors.

    The heteromeric PC-1/PC-2 polycystin complex is activated by the PC-1 N-terminus

    Kotdaji Ha, Mai Nobuhara ... Markus Delling
    Soluble fragments cleaved from the N-terminus of PC-1 activate the PC-1/PC-2 heteromeric polycystin channel, describing for the first time that the N-terminus itself is an endogenous ligand.

    Zinc shapes the folding landscape of p53 and establishes a pathway for reactivating structurally diverse cancer mutants

    Adam R Blanden, Xin Yu ... Stewart N Loh
    p53 folding is critically dependent on zinc, and a synthetic metallochaperone rescues tumorigenic mutations that reduce p53's zinc affinity as well as thermodynamic stability.

    The structures of secretory and dimeric immunoglobulin A

    Sonya Kumar Bharathkar, Benjamin W Parker ... Beth M Stadtmueller
    The structures of secretory and dimeric IgA reveal pseudosymmetric assemblies of two antibody monomers, in which possible positions of antigen-binding fragments and accessibility to receptor-binding sites are limited.

    Regulation of RUVBL1-RUVBL2 AAA-ATPases by the nonsense-mediated mRNA decay factor DHX34, as evidenced by Cryo-EM

    Andres López-Perrote, Nele Hug ... Oscar Llorca
    Cryo-EM reveals the regulation of RUVBL1 and RUVBL2 AAA-ATPases by DHX34, a helicase involved in nonsense-mediated mRNA decay (NMD), and suggests mechanisms for how RUVBL1 and RUVBL2 function in NMD.
