WebbRab GTPases regulate many steps of membrane trafficking, including vesicle formation, vesicle movement along actin and tubulin networks, and membrane fusion. These processes make up the route through which cell surface proteins are trafficked from the Golgi to the plasma membrane and are recycled. Webbprotein is transported across a membrane by protein translocators (b/w two distinct compartments) cytosol to mitochondria, ER, Peroxisomes, or Plastids vesicular transport membrane enclosed vesicles transport proteins as cargo to be dissolved in the lumen or transmembrane signal sequences
