Lysosomal fusion is fundamental to cell survival and requires HOPS, a conserved heterohexameric tethering complex. On the membranes to be fused, HOPS binds small membrane-associated GTPases and assembles SNAREs for fusion, but how the complex fulfills its function remained speculative. Here, we used cryo-electron microscopy to reveal the structure of HOPS. Unlike previously reported, significant flexibility of HOPS is confined to its extremities, where GTPase binding occurs. The SNARE-binding module is firmly attached to the core, therefore, ideally positioned between the membranes to catalyze fusion. Our data suggest a model for how HOPS fulfills its dual functionality of tethering and fusion and indicate why it is an essential part of the membrane fusion machinery. #1: ![]() タイトル: Structure of the endosomal CORVET tethering complex. 著者: Dmitry Shvarev / Caroline König / Nicole Susan / Lars Langemeyer / Stefan Walter / Angela Perz / Florian Fröhlich / Christian Ungermann / Arne Moeller / ![]() 要旨: Cells depend on their endolysosomal system for nutrient uptake and downregulation of plasma membrane proteins.

These processes rely on endosomal maturation, which requires multiple membrane fusion steps. Early endosome fusion is promoted by the Rab5 GTPase and its effector, the hexameric CORVET tethering complex, which is homologous to the lysosomal HOPS. How these related complexes recognize their specific target membranes remains entirely elusive. Here, we solve the structure of CORVET by cryo-electron microscopy and revealed its minimal requirements for membrane tethering. As expected, the core of CORVET and HOPS resembles each other. However, the function-defining subunits show marked structural differences. Notably, we discover that unlike HOPS, CORVET depends not only on Rab5 but also on phosphatidylinositol-3-phosphate (PI3P) and membrane lipid packing defects for tethering, implying that an organelle-specific membrane code enables fusion. Our data suggest that both shape and membrane interactions of CORVET and HOPS are conserved in metazoans, thus providing a paradigm how tethering complexes function. #2: ![]() タイトル: Structure of the HOPS tethering complex, a lysosomal membrane fusion machinery. 著者: Dmitry Shvarev / Jannis Schoppe / Caroline König / Angela Perz / Nadia Füllbrunn / Stephan Kiontke / Lars Langemeyer / Dovile Januliene / Kilian Schnelle / Daniel Kümmel / Florian ...著者: Dmitry Shvarev / Jannis Schoppe / Caroline König / Angela Perz / Nadia Füllbrunn / Stephan Kiontke / Lars Langemeyer / Dovile Januliene / Kilian Schnelle / Daniel Kümmel / Florian Fröhlich / Arne Moeller / Christian Ungermann / ![]() 要旨: Lysosomes are essential for cellular recycling, nutrient signaling, autophagy, and pathogenic bacteria and viruses invasion.
