Protein

Vesicle-fusing ATPase

Gene

NSF

Organism
Cricetulus griseus (Chinese hamster) (Cricetulus barabensis griseus)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

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. Interaction with AMPAR subunit GRIA2 leads to influence GRIA2 membrane cycling.1 Publication

Catalytic activityi

ATP + H2O = ADP + phosphate.

Cofactori

Mg2+1 PublicationNote: Binds 1 Mg2+ ion per subunit.1 Publication
