    c-di-GMP heterogeneity is generated by the chemotaxis machinery to regulate flagellar motility

    Bridget R Kulasekara et al.
    Real time measurements of c-di-GMP in individual cells reveal an unexpected mechanism by which the chemotaxis machinery controls c-di-GMP heterogeneity, thereby regulating flagellar-based motility.

    Mechanistic insight into the conserved allosteric regulation of periplasmic proteolysis by the signaling molecule cyclic-di-GMP

    Debashree Chatterjee et al.
    Structure-function analyses reveal the mechanistic underpinnings of inside-out transmembrane signaling that controls periplasmic proteolysis, and thereby biofilm formation, in bacteria and may be relevant in the context of other signaling proteins with similar control elements.

    Cyclic di-GMP differentially tunes a bacterial flagellar motor through a novel class of CheY-like regulators

    Jutta Nesper et al.
    Precise control of the bacterial flagellar motor determines bacterial cell dispersal and bacteria-surface interactions.

    A discriminator code–based DTD surveillance ensures faithful glycine delivery for protein biosynthesis in bacteria

    Santosh Kumar Kuncha et al.
    Using bioinformatic and biochemical approaches, the study has explained the discriminator base anomaly in bacterial tRNA(Gly) through identification of the key determinant of DTD specificity.

    H3K4 mono- and di-methyltransferase MLL4 is required for enhancer activation during cell differentiation

    Ji-Eun Lee et al.
    MLL4 (KMT2D) is a major mammalian H3K4 mono- and di-methyltransferase that is essential for enhancer activation, cell-type-specific gene expression, and cell differentiation.

    A calcium transport mechanism for atrial fibrillation in Tbx5-mutant mice

    Wenli Dai et al.
    TBX5-loss associated cardiomyocyte ectopy and atrial fibrillation is prevented by augmentation of SERCA2 activity, establishing a mechanism underlying the genetic basis for a Ca2+-dependent pathway for AF risk.

    The fail-safe mechanism of post-transcriptional silencing of unspliced HAC1 mRNA

    Rachael Di Santo et al.
    The unspliced HAC1 mRNA does not give rise to detectable protein in budding yeast, despite its cytoplasmic localization, due to a two-part post-transcriptional silencing mechanism.

    IGF2 mRNA binding protein-2 is a tumor promoter that drives cancer proliferation through its client mRNAs IGF2 and HMGA1

    Ning Dai et al.
    The IGF2 mRNA binding protein-2/IMP2, overexpressed in many common cancers, drives cancer cell proliferation by increasing the abundance of IGF2 and the oncogene HMGA1, which controls a network of effectors that enhance IGF2 action.

    Punishment insensitivity emerges from impaired contingency detection, not aversion insensitivity or reward dominance

    Philip Jean-Richard-dit-Bressel et al.
    Behavioral analyses show that individuals insensitive to punishment are afraid of aversive events, they are simply unable to change their behaviour to avoid them.

    Acetylation of histone H3 at lysine 64 regulates nucleosome dynamics and facilitates transcription

    Vincenzo Di Cerbo et al.
    The acetylation of histones at specific sites close to DNA can regulate transcription.
