Webone common feature is that most of them use small GTPases to direct coat assembly at the donor membrane. COPII coated vesicles bud from the endoplasmic reticulum to selectively export secretory cargo en route to the Golgi complex. Vesicle formation involves the stepwise recruitment of the small GTPase Sar1 and two large heterodimeric WebActin assembly can create protrusions that encompass extracellular materials. Actin can also support the processes of invagination of a membrane segment into the cytoplasm, elongation of the invagination, scission of the new vesicle from the plasma membrane, and movement of the vesicle away from the membrane. shared ownership staircasing process
