    Glycan processing in the Golgi as optimal information coding that constrains cisternal number and enzyme specificity

    Alkesh Yadav, Quentin Vagne ... Madan Rao
    A mathematical model of glycosylation in the Golgi apparatus to investigate how the fidelity of synthesising a complex glycan distribution at the plasma membrane depends on parameters such as the number of Golgi cisternae or enzyme specificity.

    A filter at the entrance of the Golgi that selects vesicles according to size and bulk lipid composition

    Maud Magdeleine, Romain Gautier ... Bruno Antonny
    The golgin GMAP-210 captures vesicles at the cis Golgi by merely recognizing the high curvature and lipid unsaturation level of transport vesicles.

    Sphingomyelin metabolism controls the shape and function of the Golgi cisternae

    Felix Campelo, Josse van Galen ... Vivek Malhotra
    Association of curvature generating proteins to the Golgi membranes by sphingomyelin metabolism essentially controls the flatness of a Golgi cisterna that is necessary for efficient sorting and export.

    Protein flexibility is required for vesicle tethering at the Golgi

    Pak-yan Patricia Cheung, Charles Limouse ... Suzanne R Pfeffer
    Atomic force microscopy reveals a floppy, dimeric, coiled coil Golgin structure that captures transport vesicles via splayed, N-terminal ends at the Golgi complex.

    Golgi membrane protein Erd1 Is essential for recycling a subset of Golgi glycosyltransferases

    Richa Sardana, Carolyn M Highland ... Scott D Emr
    Transmembrane protein Erd1 and the cytosolic receptor Vps74 cooperate to mediate early Golgi glycosyltransferase recycling in budding yeast.

    Transport of soluble proteins through the Golgi occurs by diffusion via continuities across cisternae

    Galina V Beznoussenko, Seetharaman Parashuraman ... Alberto Luini
    The soluble cargo protein albumin traverses the Golgi stack at much faster rates than procollagen aggregates, by diffusion via intercisternal continuities.

    Stapled Golgi cisternae remain in place as cargo passes through the stack

    Gregory Lavieu, Hong Zheng, James E Rothman
    The cisternae of the Golgi contain two functionally distinct domains: the central areas, which remain stationary, and the edges or rims, which are mobile.

    Inter-Golgi transport mediated by COPI-containing vesicles carrying small cargoes

    Patrina A Pellett, Felix Dietrich ... Grégory Lavieu
    Evidence that certain proteins can be transported between Golgi via structures that resemble COPI vesicles suggests that these vesicles could also be involved in the transport of proteins from the cis to the trans face of the Golgi.

    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.

    GnT1IP-L specifically inhibits MGAT1 in the Golgi via its luminal domain

    Hung-Hsiang Huang, Antti Hassinen ... Pamela Stanley
    GnT1IP-L is a membrane bound glycoprotein that interacts with MGAT1 in the Golgi, but not in the endoplasmic reticulum, to regulate complex N-glycan synthesis.
