    A choline-releasing glycerophosphodiesterase essential for phosphatidylcholine biosynthesis and blood stage development in the malaria parasite

    Abhinay Ramaprasad, Paul-Christian Burda ... Michael J Blackman
    The malaria parasite uses an enzyme called GDPD to absorb choline, an important nutrient, from the bloodstream and this is essential for the parasite to survive inside the red blood cell.

    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.

    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.

    The conserved centrosomin motif, γTuNA, forms a dimer that directly activates microtubule nucleation by the γ-tubulin ring complex (γTuRC)

    Michael J Rale, Brianna Romer ... Sabine Petry
    An evolutionarily conserved protein sequence present in diverse species like yeast, frogs, chickens, and humans binds a well-known template for microtubule nucleation, the gamma-tubulin ring complex, activating and enhancing its ability to nucleate microtubules, even under low tubulin concentrations.

    Hypoxia truncates and constitutively activates the key cholesterol synthesis enzyme squalene monooxygenase

    Hudson W Coates, Isabelle M Capell-Hattam ... Andrew J Brown
    Hypoxic accumulation of squalene, the substrate of squalene monooxygenase, triggers its proteasomal truncation to a constitutively active variant that preserves downstream sterol synthesis.

    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.

    A novel fold for acyltransferase-3 (AT3) proteins provides a framework for transmembrane acyl-group transfer

    Kahlan E Newman, Sarah N Tindall ... Marjan W Van Der Woude
    The modelled structure of a membrane protein supports the hypothesis that it has a new fold with a channel that allows a chemical group to cross the membrane to decorate surface structures.

    Disrupting the ciliary gradient of active Arl3 affects rod photoreceptor nuclear migration

    Amanda M Travis, Samiya Manocha ... Jillian N Pearring
    Dominant mutations in Arl3, linked to inherited retinal dystrophy, disrupt the active Arl3-GTP ciliary gradient and cause a defect in rod photoreceptor nuclear migration that can be rescued by elevating ciliary Arl3 activity or reducing aberrant non-ciliary Arl3 activity.

    Destabilizers of the thymidylate synthase homodimer accelerate its proteasomal degradation and inhibit cancer growth

    Luca Costantino, Stefania Ferrari ... Maria Paola Costi
    The dimer destabilizers cause a dimer-to-monomer equilibrium shift favoring the human thymidylate synthase monomer more degradable by the proteasome, thus breaking the long-standing link between inhibition and enhanced expression of the protein to fight cancer drug resistance.

    Collateral deletion of the mitochondrial AAA+ ATPase ATAD1 sensitizes cancer cells to proteasome dysfunction

    Jacob M Winter, Heidi L Fresenius ... Jared Rutter
    A common genomic deletion in various human cancers disrupts mitochondrial protein homeostasis in a way that might be targeted by existing drugs.
