Formation and interaction of membrane tubes

WebJul 20, 2024 · In this last regime, they form scaffolds that mechanically constrain membrane tubes or bud necks and spontaneously tubulate membranes . Depending on the proteins, these scaffolds can result only from self-assembling in the absence of protein–protein interactions or from direct protein–protein interactions . WebJan 15, 2024 · The application of a localized force to a membrane leads to the formation of membrane tubes or tethers, which are thin, elongated, cylindrical structures ( 1 ). Membrane tubes are involved in a wide variety of cellular processes, such as motility, mechanosensing, signaling, and intercellular and intracellular trafficking ( 2 , 3 , 4 ).
