Characteristics of the protein coding sequence
Cry9E delta-endotoxin
EN
The Cry9E protein, when expressed, protects the plants against feeding damage of larvae of the lepidopteran insect European corn borer  by selectively binding to specific sites localized on the brush border midgut epithelium of susceptible insect species.
EN
Additional Information
Cry proteins, of which Cry9E is one among many, act by selectively binding to specific sites localized on the lining of the midgut of susceptible insect species. Following binding, pores are formed that disrupt midgut ion flow, causing gut paralysis and eventual death due to bacterial sepsis. Cry9E is lethal when eaten by the larvae of certain insects and its specificity of action is directly attributable to the presence of specific binding sites in the target insects.
