The Cry proteins are solubilized in the alkaline environment of insect midgut and are then proteolytically processed to yield a toxic core fragment.

The toxin fragments of Cry proteins have 3 domains: 

Domain, I functions in pore and ion channel formations, 

Domain II is involved in receptor recognition, 

Domain III binds the receptor and affects channel properties. The toxin fragments arc believed to bind to specific high-affinity receptors present in the brush border of midgut epithelial cells

Cry proteins, in general, have no adverse effects on higher animals, including mammals since, there are no specific receptors in the gastrointestinal tracts of mammals.

Adenoviral vectors

Adenoviruses are large linear double-stranded DNA viruses. Their large size enables them to accept large inserts.

These vectors are advantageous in that they can deliver many genome copies per host cell and so typically are associated with high expression.
