Abstract
N-ethylmaleimide-sensitive fusion protein (NSF) is an essential component for the neurotransmitter or neurohormone release apparatus present in all eukaryotic cells. Here, a new NSF orthologue was characterized from the cotton bollworm, Helicoverpa armigera (Har). Northern blot exhibited a high expression in larval brain. Southern analysis indicated that a single copy of the gene is present in a haploid genome. Using antibodies labeled with fluoresceins, we directly proved that NSF is co-localized with two crucial neurohormones, prothoracicotropic hormone and diapause hormone, both of which regulate insect development. These findings suggest that Har-NSF may be involved in regulating insect neurohormone release.
