    Acute perturbation of Pet1-neuron activity in neonatal mice impairs cardiorespiratory homeostatic recovery

    Ryan T Dosumu-Johnson et al.
    Pet1 neurons actively maintain cardiorespiratory tone and dynamic range in mouse neonates and critically support the recovery response to apneas, informing brain findings in the sudden infant death syndrome.

    A novel mode of capping protein-regulation by twinfilin

    Adam B Johnston et al.
    Twinfilin functions as a pro-capping ligand of capping protein, dynamically competing with inhibitory ligands of capping proteinto control cellular actin assembly.

    Meiotic drive of female-inherited supernumerary chromosomes in a pathogenic fungus

    Michael Habig et al.
    Female-inherited supernumerary chromosomes that lack a male-inherited homolog are transmitted to all meiotic products instead of the expected half, which indicates an additional amplification of unpaired chromosomes during meiosis.

    Ubiquitin turnover and endocytic trafficking in yeast are regulated by Ser57 phosphorylation of ubiquitin

    Sora Lee et al.
    Ser57 phosphorylation regulates ubiquitin homeostasis by inhibiting deubiquitylase-mediated recycling and promoting vacuolar degradation.

    The GTPase Nog1 co-ordinates the assembly, maturation and quality control of distant ribosomal functional centers

    Purnima Klingauf-Nerurkar et al.
    The GTPase Nog1 orchestrates stalk assembly, peptidyl transferase centre maturation and polypeptide exit tunnel quality control.

    The ribosomal P-stalk couples amino acid starvation to GCN2 activation in mammalian cells

    Heather P Harding et al.
    Genetic lesions that compromise the ribosome P-stalk implicate direct signalling from the ribosome to the translation initiation factor eIF2 kinase GCN2 in the cellular response to amino acid starvation.

    Lactate-mediated epigenetic reprogramming regulates formation of human pancreatic cancer-associated fibroblasts

    Tushar D Bhagat et al.
    Lactate in pancreatic cancer micro-environment can lead to TET enzyme activation and loss of DNA methylation seen in cancer associated fibroblasts.

    Transverse tubule remodeling enhances Orai1-dependent Ca2+ entry in skeletal muscle

    Antonio Michelucci et al.
    Structural and functional analyses show that transverse tubule association with stacks of sarcoplasmic reticulum enhances Orai1-dependent Ca2+ entry to replenish Ca2+ stores, maintain Ca2+ release, and maximize force during exercise.

    RIM is essential for stimulated but not spontaneous somatodendritic dopamine release in the midbrain

    Brooks G Robinson et al.
    Midbrain dopamine neurons use sophisticated secretory machinery to establish specialized sites for action potential-evoked release of dopamine from their cell bodies and dendrites.

    A conserved Mcm4 motif is required for Mcm2-7 double-hexamer formation and origin DNA unwinding

    Kanokwan Champasa et al.
    Analysis of an essential motif in Mcm4 provides insights into replicative helicase double-hexamer formation and the first step requiring this intermediate during replication initiation.
