    Functional and structural characterization of an ECF-type ABC transporter for vitamin B12

    Joana A Santos et al.
    ECF-CbrT is a bacterial vitamin B12 transporter that is structurally different from the well-characterized transporter BtuCDF, yet has similar functional properties.

    Quantitative dissection of transcription in development yields evidence for transcription-factor-driven chromatin accessibility

    Elizabeth Eck et al.
    Confronting different models of chromatin accessibility with temporally resolved transcription profiles favors a scenario where transcription factors actively, rather than passively, drive chromatin from the inaccessible to the accessible state.

    dPob/EMC is essential for biosynthesis of rhodopsin and other multi-pass membrane proteins in Drosophila photoreceptors

    Takunori Satoh et al.
    A membrane protein complex in the endoplasmic reticulum is a key factor for the biogenesis of multi-pass transmembrane proteins, including Rh1, and its loss causes retinal degeneration.

    A feedback mechanism converts individual cell features into a supracellular ECM structure in Drosophila trachea

    Arzu Öztürk-Çolak et al.
    Cell-cell junctions and the actin cytoskeleton are key players in the organisation and patterning of the extracellular matrix (ECM) on the apical side of tracheal cells.

    Mechanism of completion of peptidyltransferase centre assembly in eukaryotes

    Vasileios Kargas et al.
    Cryo-EM reveals how the central functional site of the ribosome is assembled and provides a framework to interpret the consequences of mutations linked to leukaemia-associated ribosomopathies.

    Trade-off shapes diversity in eco-evolutionary dynamics

    Farnoush Farahpour et al.
    In a minimalistic, generic model of competitive communities in which evolution is constrained by life-history trade-offs, stable biodiversity emerges with species adapted to different functional niches.

    The cryo-EM structure of a 12-subunit variant of RNA polymerase I reveals dissociation of the A49-A34.5 heterodimer and rearrangement of subunit A12.2

    Lucas Tafur et al.
    Cryo-EM structures of RNA polymerase I reveal considerable 'transformers-like' rearrangements where one subcomplex dissociates and is replaced by one domain of another subunit, possibly as an additional layer of transcriptional control.

    Cryo-EM structures and functional properties of CALHM channels of the human placenta

    Katarzyna Drożdżyk et al.
    Members of the calcium homeostasis modulator family expressed in the placenta form large channels with unknown activation properties that harbor a lipid bilayer on the inside of a cylindrical pore.

    Sexual dimorphism in trait variability and its eco-evolutionary and statistical implications

    Susanne RK Zajitschek et al.
    Sex differences in trait variability imply that both sexes should be included in biomedical trials, using sex-specific statistical power calculations.

    Molecular dynamics-based refinement and validation for sub-5 Å cryo-electron microscopy maps

    Abhishek Singharoy et al.
    New hybrid structure determination methods leveraging the inherent biophysical properties of a macromolecule through molecular dynamics simulations provide accurate and cost-efficient ways of achieving atomic structures from high resolution cryo-electron density maps.
