    A balance of positive and negative regulators determines the pace of the segmentation clock

    Guy Wiedermann et al.
    Computational modelling together with experimental manipulation indicate that the stability and turnover of activated Notch is inextricably linked to the regulation of the pace of segmentation clock gene expression in the presomitic mesoderm.

    Physiological and pathophysiological control of synaptic GluN2B-NMDA receptors by the C-terminal domain of amyloid precursor protein

    Paula A Pousinha et al.
    The APP intracellular domain (AICD) physiologically regulates synaptic GluN2B-containing NMDA receptor current, a process that could contribute to pathological Alzheimer's disease-related synaptic failure upon increase of AICD levels in adult neurons.

    AMPylation matches BiP activity to client protein load in the endoplasmic reticulum

    Steffen Preissler et al.
    Attaching a molecule of adenosine mono-phosphate (AMP) to the BiP protein at threonine 518 regulates its chaperone activity in the endoplasmic reticulum.

    Recruitment of two dyneins to an mRNA-dependent Bicaudal D transport complex

    Thomas E Sladewski et al.
    mRNA cargo orchestrates the activation of an in vitro reconstituted dynein-dynactin-Bicaudal D-Egalitarian complex for robust processive motion on microtubules.

    Enhancer architecture sensitizes cell specific responses to Notch gene dose via a bind and discard mechanism

    Yi Kuang et al.
    DNA binding site architecture promotes Notch transcription complex degradation to sensitize developmental processes requiring long-duration signaling.

    A hypothesis on the capacity of plant odorant-binding proteins to bind volatile isoprenoids based on in silico evidences

    Deborah Giordano et al.
    It is hypothesized that volatile organic compounds emitted by plants after stress induction may be sensed by neighboring eavesdropping plants using odorant-binding proteins.

    Group size and composition influence collective movement in a highly social terrestrial bird

    Danai Papageorgiou, Damien Roger Farine
    High-resolution GPS data revealed a quadratic relationship between group size and movement, with vulturine guineafowl groups of intermediate size exhibiting the largest home-range size and greater variation in site use.

    The Ndc80 complex bridges two Dam1 complex rings

    Jae ook Kim et al.
    The ability of the Ndc80 complex to bind two Dam1 complex rings is important for chromosome attachment, and the distance between the two rings is vital for supporting growth.

    A tethered delivery mechanism explains the catalytic action of a microtubule polymerase

    Pelin Ayaz et al.
    Using linked TOG domains that each bind a curved conformation of αβ-tubulin, a microtubule polymerase catalyzes fast elongation by concentrating αβ-tubulin near the polymer end.

    Drosophila seminal sex peptide associates with rival as well as own sperm, providing SP function in polyandrous females

    Snigdha Misra, Mariana F Wolfner
    A seminal protein from a mating-male can bind sperm previously stored in his mate, providing direct benefits to the sperm from the prior male that mated with her.
