Intracellular transduction in the regulation of pheromone biosynthesis of the silkworm, Bombyx mori: suggested involvement of calmodulin and phosphoprotein phosphatase.

We have tested the effects of chemicals on bombykol production in vitro in the silkworm, Bombyx mori, to probe the biochemical steps as well as underlying mechanisms regulated by PBAN. These results suggest the involvement of calmodulin and phosphoprotein phosphatase in the intracellular signal transduction of PBAN action.
