    A stress assembly that confers cell viability by preserving ERES components during amino-acid starvation

    Margarita Zacharogianni, Angelica Aguilera-Gomez ... Catherine Rabouille
    Amino-acid starvation leads to the formation of a reversible stress assembly, the Sec body, which is a pro-survival reservoir for components of the ER exit sites.

    Chromerid genomes reveal the evolutionary path from photosynthetic algae to obligate intracellular parasites

    Yong H Woo, Hifzur Ansari ... Arnab Pain
    Analysis of chromerid algal genomes reveals how apicomplexans have evolved from free-living algae into successful eukaryotic parasites via massive losses and re-inventing functional roles of genes.

    The spatial separation of processing and transport functions to the interior and periphery of the Golgi stack

    Hieng Chiong Tie, Alexander Ludwig ... Lei Lu
    Transport machinery localizes at the cisternal rim while modification machinery localizes at the interior.

    COPI selectively drives maturation of the early Golgi

    Effrosyni Papanikou, Kasey J Day ... Benjamin S Glick
    Inactivation of the COPI vesicle coat in yeast reveals that COPI recycles early but not late Golgi proteins.

    Crumbs organizes the transport machinery by regulating apical levels of PI(4,5)P2 in Drosophila

    Johanna Lattner, Weihua Leng ... David Flores-Benitez
    The polarity protein crumbs controls apical secretion and the architecture of the apical domain by modulating PI(4,5)P2 levels and the organization of apical Rab6-, Rab11-, and Rab30-dependent trafficking.

    The metal transporter ZIP13 supplies iron into the secretory pathway in Drosophila melanogaster

    Guiran Xiao, Zhihui Wan ... Bing Zhou
    Drosophila ZIP13 (Slc39a13), a presumed zinc importer, is responsible for iron delivery to the secretory pathway.

    Ablation of SNX6 leads to defects in synaptic function of CA1 pyramidal neurons and spatial memory

    Yang Niu, Zhonghua Dai ... Jia-Jia Liu
    SNX6 regulates the distribution of a protein called Homer1b/c to distal dendrites, enabling the latter to stabilize the synapses and thereby support memory formation.

    Cryo-EM structures of human ZnT8 in both outward- and inward-facing conformations

    Jing Xue, Tian Xie ... Xiao-chen Bai
    Cryo-EM analysis of human ZnT8 reveals a large conformational change of TMD during the transport cycle.

    Distinct trafficking routes of polarized and non-polarized membrane cargoes in Aspergillus nidulans

    Georgia Maria Sagia, Xenia Georgiou ... Sofia Dimou
    Unconventional secretion of a plasma membrane purine transporter via Golgi-bypass is established at an early ER-associated secretory compartment revealing that specific cargoes define alternative trafficking routes.
    1. Neuroscience

    Localization, proteomics, and metabolite profiling reveal a putative vesicular transporter for UDP-glucose

    Cheng Qian, Zhaofa Wu ... Yulong Li
    Identification of novel vesicular transporters will shed light on to expanding the chemical diversity of neurotransmitters or neuromodulators.
