Membrane curvature

Membrane curvature is the deflection of cellular membranes. The generation of membrane curvature is essential for cellular processes such as cell division, and endocytosis and exocytosis. Membrane curvature can be induced by protein association with the membrane or by changes in local membrane lipid concentration.

    HIV particles incorporate host membrane proteins into their envelope to evade the immune system and infect other cells. A study now shows that Gag assembly on the host cell membrane produces a raft-like nanodomain favourable for protein partitioning due to a transbilayer coupling mechanism assisted by long saturated chain lipids and cholesterol.

    Compared with most intracellular vesicles, the autophagosome is formed by an unusual event of vesicle budding involving an elusive sequence of membrane expansions that ends with a double membrane vesicle. It is now shown that actin polymerization inside the forming autophagosome is a driving force for the expansion and assembly of a functional autophagosome.

    Clathrin-independent endocytosis removes membrane receptors and other proteins from the cell surface, yet the mechanisms controlling this process remain unclear. Galectin-3 is now shown to regulate the biogenesis of a subpopulation of clathrin-independent carriers (CLICs). Galectin-3 binds to glycosylated cargo proteins and interacts with membrane glycosphingolipids to induce membrane deformation and CLIC formation.
