UniProtKB - P54351 (NSF2_DROME)
Protein
Vesicle-fusing ATPase 2
Gene
Nsf2
Organism
Drosophila melanogaster (Fruit fly)
Status
Functioni
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 (By similarity).By similarity
Caution
It is uncertain whether Met-1 or Met-9 is the initiator.Curated
Catalytic activityi
- EC:3.6.4.6
Cofactori
Mg2+By similarityNote: Binds 1 Mg2+ ion per subunit.By similarity
