  • Signal peptide:  NA
  • Modification:  T18 Leucine amide
  • Glycosylation:  NA

Activity

  • Function:  A hormone that controls sex pheromone production in females and pheromone responsiveness in male. Also mediates visceral muscle contractile activity (myotropic activity) (By similarity).
  • Mechanism:  Juvenile hormone seems to allow PBAN release, which then induces pheromone biosynthesis.
