    A gene regulatory network for neural induction

    Katherine E Trevers, Hui-Chun Lu ... Claudio D Stern
    A comprehensive resource based on analysis of the responses of embryonic ectoderm cells to signals from the 'organizer' (the node) including transcriptional responses and epigenetic changes with fine temporal dynamics, predicted regulatory interactions, and conservation among vertebrates.

    Olfactory responses of Drosophila are encoded in the organization of projection neurons

    Kiri Choi, Won Kyu Kim, Changbong Hyeon
    The organization of olfactory projection neurons and their synaptic connectivity with third-order neurons studied along with olfactory responses suggest that the labeled-line design is partially at work in the Drosophila olfactory system.

    The structure of behavioral variation within a genotype

    Zachary Werkhoven, Alyssa Bravin ... Benjamin L de Bivort
    Multidimensional analysis of data from high-throughput behavioral assays reveals many independent axes of behavioral variation among inbred animals reared in the same environment.

    CM1-driven assembly and activation of yeast γ-tubulin small complex underlies microtubule nucleation

    Axel F Brilot, Andrew S Lyon ... David A Agard
    Cryo-EM structures reveal that the conserved CM1 motif drives γTuRC assembly by bridging adjacent γTuSC.

    A mechanism for hunchback promoters to readout morphogenetic positional information in less than a minute

    Jonathan Desponds, Massimo Vergassola, Aleksandra M Walczak
    Maternal positional information in the fly embryo can be read rapidly in spite of the gene-expression bottleneck and general examples of regulatory architectures that combine speed and accuracy are provided.

    New hypotheses of cell type diversity and novelty from orthology-driven comparative single cell and nuclei transcriptomics in echinoderms

    Anne Meyer, Carolyn Ku ... Veronica Hinman
    Understanding novel cell types and their evolutionary history is re-evaluated using single nuclei transcriptomic approaches and their inferred underlying gene regulatory networks.

    Molecular basis for the role of disulfide-linked αCTs in the activation of insulin-like growth factor 1 receptor and insulin receptor

    Jie Li, Jiayi Wu ... Eunhee Choi
    A critical role of aCT in the distinct activation mechanism of insulin receptor and insulin-like growth factor 1 receptor.

    An autoinhibitory clamp of actin assembly constrains and directs synaptic endocytosis

    Steven J Del Signore, Charlotte F Kelley ... Avital Adah Rodal
    Autoinhibition allows synaptic endocytic actin regulators to pre-deploy to synaptic membranes at high concentrations and constrains actin assembly to productive events.

    Molecular basis of the PIP2-dependent regulation of CaV2.2 channel and its modulation by CaV β subunits

    Cheon-Gyu Park, Wookyung Yu, Byung-Chang Suh
    The anchoring properties of CaV β2 subunits to the plasma membrane determine the biophysical states of CaV2.2 channels by regulating PIP2 coupling to the nonspecific phospholipid-binding site in the I–II loop.

    Structural basis for the disaggregase activity and regulation of Hsp104

    Alexander Heuck, Sonja Schitter-Sollner ... Tim Clausen
    Protein disaggregases employ two mechanically-linked ATPase rings that are under steric control by a wrapped-around coiled-coil belt.
