    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.

    The flagellar motor of Vibrio alginolyticus undergoes major structural remodeling during rotational switching

    Brittany L Carroll et al.
    In situ structures of the flagellar motors genetically docked in CCW and CW rotational states reveal major rearrangement that facilitates rotational switch in Vibrio alginolyticus..

    Multiple Wnts act synergistically to induce Chk1/Grapes expression and mediate G2 arrest in Drosophila tracheoblasts

    Amrutha Kizhedathu et al.
    Wnts can act synergistically to affect G2 arrest via transcriptional upregulation of a Checkpoint Kinase in the absence of any detectable DNA damage.

    Cadherin clusters stabilized by a combination of specific and nonspecific cis-interactions

    Connor J Thompson et al.
    A combined experimental and computational approach was developed to understand lateral interactions between membrane-bound proteins and used to quantify the contributions of specific and non-specific interactions to cadherin cis-binding kinetics.

    Genetic mapping of etiologic brain cell types for obesity

    Pascal N Timshel et al.
    Unbiased computational integration of single-cell- and human genetics data shows that susceptibility to obesity is driven by a broad set of neuronal populations across the brain.

    Genome-wide alterations of uracil distribution patterns in human DNA upon chemotherapeutic treatments

    Hajnalka L Pálinkás et al.
    Human genomic DNA contains uracil in the late replicating, constitutive heterochromatic regions, while treatment with drugs perturbing thymidylate biosynthesis shifts the uracil distribution pattern towards the euchromatin in UNG-inhibited cells.

    Growth-factor-mediated coupling between lineage size and cell fate choice underlies robustness of mammalian development

    Néstor Saiz et al.
    A mechanistic basis is provided for the regulative ability of the mammalian embryo offering a long-sought explanation for coordinating cell behaviors at the population level ensuring robustness in developmental outcome.

    Long-term potentiation is independent of the C-tail of the GluA1 AMPA receptor subunit

    Javier Díaz-Alonso et al.
    Despite being the key element of the classic model for excitatory synaptic plasticity, the cytoplasmic AMPA receptor C-tail is not required for hippocampal LTP.

    Post-tetanic potentiation lowers the energy barrier for synaptic vesicle fusion independently of Synaptotagmin-1

    Vincent Huson et al.
    Modulation of the energy barrier for membrane fusion is a common mechanism by which sensors in the synapse produce supralinear calcium dependence of vesicle release and short-term synaptic potentiation.

    Cell-cycle-gated feedback control mediates desensitization to interferon stimulation

    Anusorn Mudla et al.
    Cell cycle gating enables a temporal compartmentalization of negative vs positive feedback control processes, leading to differential responses to repetitive interferon stimulations.
