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
