    Overriding FUS autoregulation in mice triggers gain-of-toxic dysfunctions in RNA metabolism and autophagy-lysosome axis

    Shuo-Chien Ling et al.
    Elevating FUS level by saturating autoregulation loop in mice causes aggressive motor neuron disease via disrupting protein and RNA homeostasis.

    The autoregulation of a eukaryotic DNA transposon

    Corentin Claeys Bouuaert et al.
    A DNA transposon, or ‘jumping gene’, controls its amplification within a genome through a competition between the enzyme multimers that are responsible for its mobility.

    Acidic C-terminal domains autoregulate the RNA chaperone Hfq

    Andrew Santiago-Frangos et al.
    Modeling and biophysics show that the unstructured acidic tail of the Sm protein Hfq mimics nucleic acid to auto inhibit its chaperone activity, preventing Hfq from being sequestered by inauthentic substrates and providing insight into the evolution of Hfq's chaperone function among bacterial genera.

    Signaling Systems: Transferring information without distortion

    Steven S Andrews et al.
    Despite employing diverse molecular mechanisms, many different cell signaling systems avoid losing information by transmitting it in a linear manner.

    Tissue-specific regulation of BMP signaling by Drosophila N-glycanase 1

    Antonio Galeone et al.
    N-glycanase 1 is required for a BMP autoregulatory loop in the visceral mesoderm and for intestinal development in Drosophila.

    Evolutionary changes in transcription factor coding sequence quantitatively alter sensory organ development and function

    Simon Weinberger et al.
    The coding sequences of a very highly conserved family of neurogenic transcription factors from different species have evolved to generate proteins that have different life times causing them to display quantitatively different neural induction potentials.

    A cellular and regulatory map of the cholinergic nervous system of C. elegans

    Laura Pereira et al.
    Analyzing a map of all cholinergic neurons in the nematode C. elegans shows how these neurons are embedded in the C. elegans connectome and reveals the regulatory factors controlling their development.

    A feedback loop between nonsense-mediated decay and the retrogene DUX4 in facioscapulohumeral muscular dystrophy

    Qing Feng et al.
    Expression of the disease gene DUX4 inhibits RNA quality control in skeletal muscle, thereby stabilizing thousands of aberrant RNAs, including its own transcript.

    Odd-paired controls frequency doubling in Drosophila segmentation by altering the pair-rule gene regulatory network

    Erik Clark, Michael Akam
    The organisation of the Drosophila embryo into segmental units is orchestrated by combinatorial regulatory interactions between spatially patterned and temporally patterned transcription factors.

    The Glide/Gcm fate determinant controls initiation of collective cell migration by regulating Frazzled

    Tripti Gupta et al.
    The role of the Frazzled chemoattractant receptor is to triggers migration initiation as part of the glial developmental program induced by the Glide/Gcm transcription factor.
