The study aims to characterize novel functions of NSF in Golgi membrane fusion and SNARE complex dynamics.
Characterization of mammalian NSF (G274E) and Drosophila NSF (comatose) mutants.
Analysis of NSF function during cell-free Golgi cisternae assembly from mitotic Golgi fragments.
Investigated ATPase-independent NSF activity during the reassembly phase of Golgi membranes.
NSF disassembles Golgi SNAREs during mitotic Golgi fragmentation and is essential for membrane fusion.
GATE-16 binding to GOS-28 is facilitated by NSF/alpha-SNAP in an ATP-dependent but hydrolysis-independent manner.
GATE-16 prevents GOS-28 from binding to its cognate t-SNARE, syntaxin-5, during Golgi reassembly.

Characterization of NSF activities shows their critical role in Golgi membrane fusion, indicating conserved mechanisms across species.

Müller et al. (2002) studied this question.
