    Open Access
    Nanoscale membrane assemblies of sphingolipids, cholesterol, and certain proteins, also known as lipid rafts, play a crucial role in facilitating a broad range of important cell functions. Whereas on living cell membranes ...

  • Sphingolipid metabolic flow controls phosphoinositide turnover at the trans Golgi network 

    Capasso, Serena; Sticco, Lucia; Rizzo, Riccardo; Pirozzi, Marinella; Russo, Domenico; Dathan, Nina A.; Campelo, Felix; Galen, Josse van; Hölttä-Vuori, Maarit; Turacchio, Gabriele; Hausser, Angelika; Malhotra, Vivek; Riezman, Isabelle; Riezman, Howard; Ikonen, Elina; Luberto, Chiara; Parashuraman, Seetharaman; Luini, Alberto; Angelo, Giovanni D (Embo press, 2017-04-10)
    Article
    Open Access
    Sphingolipids are membrane lipids, which are globally required for eukaryotic life. Sphingolipid composition varies among endomembranes with pre- and post-Golgi compartments being poor and rich in sphingolipids, respectively. ...

  • Sphingomyelin metabolism controls the shape and function of the Golgi cisternae 

    Campelo, Felix; Galen, Josse van; Turacchio, Gabriele; Parashuraman, Seetharaman; Kozlov, Michael M.; Garcia-Parajo, Maria F.; Malhotra, Vivek (eLife Sciences Publications, 2017-05-13)
    Article
    Open Access
    The flat Golgi cisterna is a highly conserved feature of eukaryotic cells, but how is this morphology achieved and is it related to its function in cargo sorting and export? A physical model of cisterna morphology led us ...
