    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.

    The Mla pathway in Acinetobacter baumannii has no demonstrable role in anterograde lipid transport

    Matthew J Powers et al.
    An outer membrane vesicle pulse-chase assay demonstrates that the Acinetobacter baumannii Mla system is a retrograde lipid transporter.

    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.

    Sox17 and β-catenin co-occupy Wnt-responsive enhancers to govern the endoderm gene regulatory network

    Shreyasi Mukherjee et al.
    Genomic analysis of Xenopus gastrula reveal that the transcription factor Sox17 interacts with the Wnt signaling effector ß-catenin on enhancers to regulate the transcriptional program underlying endoderm germ layer formation.

    The peroxisome counteracts oxidative stresses by suppressing catalase import via Pex14 phosphorylation

    Kanji Okumoto et al.
    H2O2-induced phosphorylation at Ser232 of Pex14 spatiotemporally regulates peroxisomal import of catalase, functioning in counteracting action against oxidative stress by the increase of cytosolic catalase.

    A missense in HSF2BP causing primary ovarian insufficiency affects meiotic recombination by its novel interactor C19ORF57/BRME1

    Natalia Felipe-Medina et al.
    Genetic and biochemical analysis reveal a variant in HSF2BP causing POI and C19ORF57/BRME1 as an interactor and stabilizer of HSF2BP by forming a complex with BRCA2, RAD51, RPA and PALB2.

    Ca2+-dependent release of synaptotagmin-1 from the SNARE complex on phosphatidylinositol 4,5-bisphosphate-containing membranes

    Rashmi Voleti et al.
    Ca2+-free synaptotagmin-1 binds to neuronal SNARE complexes anchored on nanodiscs, and Ca2+ releases this interaction to induce tight, specific binding to PIP2-containing membranes.

    MAPK activity dynamics regulate non-cell autonomous effects of oncogene expression

    Timothy J Aikin et al.
    The temporal patterns of MAPK activity differentially regulate cell autonomous and non-cell autonomous effects of oncogene expression.
