    Structures of TorsinA and its disease-mutant complexed with an activator reveal the molecular basis for primary dystonia

    F Esra Demircioglu et al.
    High resolution structures of the essential human AAA+ ATPase TorsinA and its disease mutant in complex with an activator reveal details of the interaction that will guide drug design and further functional characterization.

    Lysosomal membrane glycoproteins bind cholesterol and contribute to lysosomal cholesterol export

    Jian Li, Suzanne R Pfeffer
    LAMP proteins, the major glycoproteins of the lysosome membrane, bind cholesterol directly and specifically, and interact with NPC1 and NPC2 proteins as part of the lysosomal cholesterol export process.

    Nuclear receptor LRH-1/NR5A2 is required and targetable for liver endoplasmic reticulum stress resolution

    Jennifer L Mamrosh et al.
    LRH-1/NR5A2 responds to ER stress by inducing a novel pathway that is required for stress resolution in mice and can be targeted by LRH-1 agonists.

    How lamina-associated polypeptide 1 (LAP1) activates Torsin

    Brian A Sosa et al.
    LAP1 adopts an AAA+ like fold that, while unable to bind nucleotide, can enhance ATPase activity in the neighboring TorsinA protomer in an unusual heterohexameric ring, via an arginine finger.

    An elusive electron shuttle from a facultative anaerobe

    Emily Mevers et al.
    The identification of ACNQ as an extracellular electron shuttle solves a longstanding problem in bacterial physiology and provides new tool for bioenergy development.

    Dynamic control of hippocampal spatial coding resolution by local visual cues

    Romain Bourboulou et al.
    Hippocampal spatial coding resolution can quickly adapt to local visual cues within a given environment.

    Enrichment drives emergence of functional columns and improves sensory coding in the whisker map in L2/3 of mouse S1

    Amy M LeMessurier et al.
    Sensory enrichment creates a more columnar, less salt-and-pepper whisker map in somatosensory cortex, showing that impoverished experience contributes to intermixed tuning in rodent sensory maps.

    A terminal selector prevents a Hox transcriptional switch to safeguard motor neuron identity throughout life

    Weidong Feng et al.
    A molecular mechanism that involves highly conserved transcription factors enables cholinergic motor neurons of the nematode Caenorhabditis elegans to become and remain functional.

    Thioredoxin-1 distinctly promotes NF-κB target DNA binding and NLRP3 inflammasome activation independently of Txnip

    Jonathan Muri et al.
    The thioredoxin-1 (Trx1) system promotes inflammation by positively regulating both NLRP3 inflammasome responses, by detoxifying excessive ROS independently of Txnip and NF-κB binding to target DNA.
