NSF--fusion and beyond.
NSF (N-ethylmaleimide-sensitive fusion protein) was the first protein to be isolated as a crucial factor in intracellular membrane-fusion events, such as the fusion of synaptic vesicles with the presynaptic membrane during neurotransmission. Although the activation of membrane SNARE proteins for subsequent fusion is clearly a primary role of NSF, recent studies have provided surprising evidence that NSF also interacts with glutamate receptors at the postsynaptic membrane in a way that does not seem to involve SNAREs. These results suggest that NSF might act as a molecular chaperone not only on SNAREs but also of other proteins.[1]References
