    Site-specific effects of neurosteroids on GABAA receptor activation and desensitization

    Yusuke Sugasawa et al.
    Differential, state-dependent occupancy of three discrete binding sites on α1β3 GABAA receptors determines whether a specific neurosteroid analogue potentiates or inhibits GABA-elicited currents or competitively antagonizes neurosteroid action.

    The transcriptional elongation rate regulates alternative polyadenylation in yeast

    Joseph V Geisberg et al.
    The elongation rate of RNA polymerase II broadly affects the profile of poly(A) sites, and hence 3' mRNA isoforms, and it can mediate alternative polyadenylation in response to environmental conditions.

    Vascular dimorphism ensured by regulated proteoglycan dynamics favors rapid umbilical artery closure at birth

    Sumeda Nandadasa et al.
    Morphologic, molecular, biomechanical and computational analyses show that the specialized extracellular matrix architecture of the umbilical artery contributes to its rapid closure at birth and regulates smooth muscle cell differentiation.

    Identification of protein-protected mRNA fragments and structured excised intron RNAs in human plasma by TGIRT-seq peak calling

    Jun Yao et al.
    Human plasma contains protein-protected mRNA fragments, myriad repeat RNAs, and novel intron RNAs, including a family of structured full-length excised introns, some corresponding to mirtron pre-miRNAs and agotrons.

    A cross-kingdom conserved ER-phagy receptor maintains endoplasmic reticulum homeostasis during stress

    Madlen Stephani et al.
    C53 bridges selective autophagy with ribosome-associated quality control at the endoplasmic reticulum.

    Hedgehog signaling is required for endomesodermal patterning and germ cell development in the sea anemone Nematostella vectensis

    Cheng-Yi Chen et al.
    The dependence of Nematostella germ cell specification on zygotic Hedgehog pathway activity supports the hypothesis that the eumetazoan common ancestor segregated its germline by inductive signals rather than maternal determinants.

    Genome duplication in Leishmania major relies on persistent subtelomeric DNA replication

    Jeziel Dener Damasceno et al.
    Duplication of Leishmania chromosomes combines S-phase DNA replication initiated at a single internal region with subtelomeric DNA replication detectable outside S-phase, potentially explaining genome plasticity in this important parasite.

    Structural analysis of the Legionella pneumophila Dot/Icm type IV secretion system core complex

    Clarissa L Durie et al.
    The structure of the Legionella pneumophilaType IV secretion system provides the detailed molecular model of this complex molecular machine required for pathogenesis.

    Cryo-EM reveals species-specific components within the Helicobacter pylori Cag type IV secretion system core complex

    Michael J Sheedlo et al.
    The structure of a Type IV secretion system provides a framework for understanding assembly of a protein-injection machine.

    An ER translocon for multi-pass membrane protein biogenesis

    Philip T McGilvray et al.
    A set of ER-localized membrane proteins whose loss causes developmental diseases in humans, assemble with Sec61 into a translocon that facilitates the biogenesis of hundreds of different multi-pass membrane proteins.
