    Structure and mechanism of the Mrp complex, an ancient cation/proton antiporter

    Julia Steiner, Leonid Sazanov
    Structure of the Mrp antiporter, an ancestor of respiratory complex I, suggests a mechanism of coupling between cation and proton translocation, applicable to a large family of related membrane proteins.

    Catecholaminergic challenge uncovers distinct Pavlovian and instrumental mechanisms of motivated (in)action

    Jennifer C Swart et al.
    Motivational coupling of action to reward and inhibition to punishment is subserved by dissociable learning and choice processes, and is modulated by dopamine/noradrenaline transporter blockade.

    Cryo-EM structures reveal specialization at the myosin VI-actin interface and a mechanism of force sensitivity

    Pinar S Gurel et al.
    Cryo-EM structures of actomyosin VI in multiple nucleotide states reveal a unique actin-myosin interface and a mechanism of force-sensitivity; furthermore, myosin VI remodels F-actin, suggesting a role for actin structural plasticity during force generation.

    Mechanism for differential recruitment of orbitostriatal transmission during actions and outcomes following chronic alcohol exposure

    Rafael Renteria et al.
    Chronic alcohol exposure results in a long-lasting, enhanced endocannabinoid signalling at orbitostriatal synapses that is expressed in a projection-, synapse-, and behaviorally computation-specific manner.

    Down regulation of vestibular balance stabilizing mechanisms to enable transition between motor states

    Romain Tisserand et al.
    Down regulation of the gain from the vestibular sensory sources prior to the initiation of movement is a motor control solution to overcome the reflex-stabilizing mechanisms to enable motion from a postural orientation.

    Super-resolution microscopy reveals majorly mono- and dimeric presenilin1/γ-secretase at the cell surface

    Abril Angélica Escamilla-Ayala et al.
    Super-resolution microscopy sets a new strategy to comprehend the membrane organization of γ-secretase at single complex resolution identifying nanodomain associations and its diffusion in situ in the living membrane.

    Molecular mechanisms of human P2X3 receptor channel activation and modulation by divalent cation bound ATP

    Mufeng Li et al.
    Structural, computational and functional approaches reveal the role of an extended acidic chamber near the nucleotide binding site in activation of P2X3 receptor channels by divalent-bound ATP.

    The anticancer natural product ophiobolin A induces cytotoxicity by covalent modification of phosphatidylethanolamine

    Christopher Chidley et al.
    An unbiased genetic screen in human cells shows that the molecular target of a natural product with promising anticancer activity is a membrane phospholipid.

    Structural and kinetic analysis of the COP9-Signalosome activation and the cullin-RING ubiquitin ligase deneddylation cycle

    Ruzbeh Mosadeghi et al.
    The general principles that underlie the mechanism of action of the COP9-Signalosome, a key regulator of the largest family of ubiquitin ligase enzymes in human cells, have been identified using structural and kinetic techniques.
