Bt protoxins are required to convert to a smaller activated form by insect midgut proteases to exert toxicity against insect pests. Serine protease inhibitors (serpins) play a valuable part in gut protease of insect that hamper digestive proteases activity of insects. Whether the insect serpins induced by Bt protoxin affect the insecticidal activity were rare studied. Here, we identified a serpin-e gene from Helicoverpa armigera, which had potential RCL (Reactive Center Loop) region near the C-terminus like other serpin proteins. It widely expressed in diff
