Vesicle-fusing ATPase (NSF)

Required for vesicle-mediated transport. Catalyzes the fusion of transport vesicles within the Golgi cisternae.

Is also required for transport from the endoplasmic reticulum to the Golgi stack. Seems to function as a fusion protein required for the delivery of cargo proteins to all compartments of the Golgi stack independent of vesicle origin.
