    The SARS-CoV-2 accessory protein Orf3a is not an ion channel, but does interact with trafficking proteins

    Alexandria N Miller, Patrick R Houlihan ... David E Clapham
    SARS coronaviruses encode several mysterious proteins such as Orf3a and, in contrast to what has been claimed, Orf3a is not an ion channel but rather disrupts cellular trafficking by binding to the protein sorting complex known as HOPS.

    RNA sequence to structure analysis from comprehensive pairwise mutagenesis of multiple self-cleaving ribozymes

    Jessica M Roberts, James D Beck ... Eric J Hayden
    A high-throughput analysis of several self-cleaving ribozymes reveals the effect of every possible mutation, and every possible pair of mutations, and how patterns in the relative activity data can be mapped to canonical and non-canonical structural elements.

    Muscle calcium stress cleaves junctophilin1, unleashing a gene regulatory program predicted to correct glucose dysregulation

    Eshwar R Tammineni, Lourdes Figueroa ... Eduardo Rios
    Novel components in the pathway from malignant hyperthermia to diabetes include promotion of a kinase that impedes glycogen synthesis, increased lysis of junctophilin1 and gene regulatory actions by a junctophilin fragment, surprisingly predicted to oppose the effects of elevated calcium.

    Structures of human dynein in complex with the lissencephaly 1 protein, LIS1

    Janice M Reimer, Morgan E DeSantis ... Andres E Leschziner
    Structures of human cytoplasmic dynein-1 bound to its regulator LIS1 reveal the interfaces involved in forming the complex and provide a context for disease-linked mutations.

    A mechanism of uncompetitive inhibition of the serotonin transporter

    Shreyas Bhat, Ali El-Kasaby ... Walter Sandtner
    Biochemical and electrophysiological approaches show that the amphetamine derivative ECSI#6 is an uncompetitive inhibitor of the serotonin transporter and thus the first ever characterized ligand of a solute carrier of this type.

    Mechanism of Ca2+ transport by ferroportin

    Jiemin Shen, Azaan Saalim Wilbon ... Yaping Pan
    Cryo-EM structure and functional analyses show that human iron exporter ferroportin (Fpn) can bind and transport calcium ions and the transport activity is reduced when the concentration of ferrous ions is high.

    Inhibition of the proton-activated chloride channel PAC by PIP2

    Ljubica Mihaljević, Zheng Ruan ... Zhaozhu Qiu
    PIP2 inhibits the proton-activated chloride (PAC) channel by selectively stabilizing its desensitized state.

    Improved ANAP incorporation and VCF analysis reveal details of P2X7 current facilitation and a limited conformational interplay between ATP binding and the intracellular ballast domain

    Anna Durner, Ellis Durner, Annette Nicke
    Comparision of current and fluorescent kinetics from P2X7 receptor mutants labeled with the fluorescent amino acid ANAP suggests that the characteristic P2X7 current facilitation involves changes in channel gating rather than interactions or conformational changes of its intracellular ballast domain.

    Structures of RecBCD in complex with phage-encoded inhibitor proteins reveal distinctive strategies for evasion of a bacterial immunity hub

    Martin Wilkinson, Oliver J Wilkinson ... Mark S Dillingham
    New cryoEM structures reveal how small bacteriophage proteins suppress bacterial immunity.

    Computational design of peptides to target NaV1.7 channel with high potency and selectivity for the treatment of pain

    Phuong T Nguyen, Hai M Nguyen ... Vladimir Yarov-Yarovoy
    Rationally designed peptide inhibitors of human voltage-gated channels have transformative potential to define a new class of biologics to treat pain.
