[[Image:Consurf_key_small.gif|200px|right]]
N-ethylmaleimide-sensitive factor (NSF) is a hexameric ATPase which primes and/or dissociates SNARE complexes involved in intracellular fusion events. Each NSF protomer contains three domains: an N-terminal domain required for SNARE binding and two ATPase domains, termed D1 and D2, with D2 being required for oligomerization. We have determined the 1.9 A crystal structure of the D2 domain of NSF complexed with ATP using multi-wavelength anomalous dispersion phasing. D2 consists of a nucleotide binding subdomain with a Rossmann fold and a C-terminal subdomain, which is structurally unique among nucleotide binding proteins. There are interactions between the ATP moiety and both the neighboring D2 protomer and the C-terminal subdomain that may be important for ATP-dependent oligomerization. Of particular importance are three well-ordered and conserved lysine residues that form ionic interactions with the beta- and gamma-phosphates, one of which likely contributes to the low hydrolytic activity of D2.

Function

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.
