Protein coding sequence
Cry1B.34 is a chimeric protein consisting of sequences from cry1B-class (1470 base pairs), cry1Ca1 (522 base pairs) and cry9Db1 (1458 base pairs long), all sourced from Bacillus thuringiensis. The protein is active against lepidoptera pests. It acts by forming non-specific, ion conducting pores in the apical membrane of midgut epithelial cells, which causes a disruption of the midgut epithelium and leads to death.EN
