    An improved fluorescent noncanonical amino acid for measuring conformational distributions using time-resolved transition metal ion FRET

    William N Zagotta et al.
    Time-resolved transition metal ion fluorescence resonance energy transfer using a fluorescent, noncanonical amino acid donor and metal ion acceptor measures distances and distance distributions in proteins, allowing the equilibrium distributions among conformational states to be accurately determined.

    Fine-tuned repression of Drp1-driven mitochondrial fission primes a ‘stem/progenitor-like state’ to support neoplastic transformation

    Brian Spurlock et al.
    A mitochondria-based 'priming' of stemness happens by fine-tuned repression of the level or activity of the master regulator of mitochondrial fission, Drp1, which supports carcinogen-induced transformation in a keratinocyte model.

    SUMOylation contributes to proteostasis of the chloroplast protein import receptor TOC159 during early development

    Sonia Accossato et al.
    SUMOylation contributes to the fine-tuning of the proteostatic equilibrium of essential chloroplast protein import receptor TOC159 at early plant development.

    Crosstalk between the chloroplast protein import and SUMO systems revealed through genetic and molecular investigation in Arabidopsis

    Samuel James Watson et al.
    The small ubiquitin-like modifier system directly regulates components of the chloroplast protein import apparatus, that is, TOC proteins, to control chloroplast biogenesis and plant development.

    Activity-dependent modulation of synapse-regulating genes in astrocytes

    Isabella Farhy-Tselnicker et al.
    RNA sequencing and genetic mouse models reveal that transcriptional changes to astrocytes in the developing cortex are not intrinsic but influenced by their environment and determine that expression of astrocyte synapse-regulating genes and neuronal synaptogenesis is modulated by ongoing astrocyte-neuron communication.

    Lipid droplets and ferritin heavy chain: a devilish liaison in human cancer cell radioresistance

    Luca Tirinato et al.
    Lipid Droplet accumulation is a fingerprint shared by different human cancer radioresistant cells and their biogenesis strongly depend on FTH1 presence.

    Activity-dependent Golgi satellite formation in dendrites reshapes the neuronal surface glycoproteome

    Anitha P Govind et al.
    Neuronal activity triggers the dispersal of the Golgi into dendritic Golgi satellites, leading to reshaping of the neuronal surface glycoproteome through processing of glycans to mature, sialic acid-containing forms.

    Calcium dependence of neurotransmitter release at a high fidelity synapse

    Abdelmoneim Eshra et al.
    The Ca2+-dependence of vesicle priming, fusion, and replenishment at cerebellar mossy fiber boutons show a prominent Ca2+-dependent priming step, a shallow non-saturating dose-response curve up to 50 µM, and little Ca2+-dependence of sustained vesicle replenishment.

    End-of-life targeted degradation of DAF-2 insulin/IGF-1 receptor promotes longevity free from growth-related pathologies

    Richard Venz et al.
    Inducible degradation of the insulin/insulin-like growth factor-1 receptor shows that a doubling in lifespan is possible even at extremely old ages in an organism.

    Ectocytosis prevents accumulation of ciliary cargo in C. elegans sensory neurons

    Adria Razzauti, Patrick Laurent
    Disposal of ciliary proteins via ectosomes budding from cilia tip or cilia base acts as a safeguard mechanism when cilia trafficking functions are impaired.
