| Research Abstract |
ENF peptides are insect cytokines that possesses diverse biological activities such as larval growth regulation, cell proliferation, and stimulation of immune cells. In the present study, we constructed the expression systems of ENF peptides using the methylotrophic yeast Pichia pastoris, which is an efficient host for high-level production of heterologous proteins. To inhibit degradation by protease, we developed the method to produce peptides fused to thioredoxin and we successfully produced ENF peptides efficiently. In addition, we studied the interactions between ENF peptides and GBP-BP that is related to the end of the activation of ENF peptides.
