Protein attributes

Sequence length	1178 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Promotes colloidosmotic lysis by binding to the midgut epithelial cells of many lepidopteran larvae.
Developmental stage	The crystal protein is produced during sporulation and is accumulated both as an inclusion and as part of the spore coat.
Biotechnological use	Introduced by genetic manipulation and expressed in insect-resistant cotton and tomato by Calgene (Monsanto) and in maize by Dekalb Genetics.
Miscellaneous	Toxic segment of the protein is located in the N-terminus.
Sequence similarities	Belongs to the delta endotoxin family.
