Abstract:
In many moth species regulation of pheromone production has been attributed to the timely release of a pheromone biosynthesis activating neuropeptide (PBAN). The gene encoding PBAN has been sequenced in two moth species. Immunochemical studies as well as in situ hybridization and Northern analysis of PBAN encoding mRNA have localized the neuroendocrine cells responsible for the production of PBAN and have traced the neuronal network of PBAN immunoreactivity. Release into the bloodstream has been demonstrated, the target tissue delineated, and the signal transduction pathway and its modulation analyzed. This paper reviews the current status of research concerning the neuroendocrine control of pheromone production in Lepidopterans and presents some recent developments concerning the receptors involved in the pheromonotropic activity. In this study, we report on the use of a biologically active photoaffinity-biotin-labeled derivative of PBAN N-[N-(4-azido-tetrafluorobenzoyl-biocytinyloxyl-succinimide) and show the presence of a protein (estimated molecular weight of 50 kDa) which specifically binds to PBAN in membrane preparations of pheromone glands.
