== Function ==
[https://www.uniprot.org/uniprot/NSF_CRIGR NSF_CRIGR] 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. Seem 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.

== Publication Abstract from PubMed ==
N-ethylmaleimide-sensitive factor (NSF) is a hexameric ATPase essential for eukaryotic vesicle fusion. Along with SNAP proteins, it disassembles cis-SNARE complexes upon ATP hydrolysis, preparing SNAREs for trans complex formation. We have determined the crystal structure of the N-terminal domain of NSF (N) to 1.9 A resolution. N contains two subdomains which form a groove that is a likely SNAP interaction site. Unexpectedly, both N subdomains are structurally similar to domains in EF-Tu. Based on this similarity, we propose a model for a large conformational change in NSF that drives SNARE complex disassembly.
