Cry1B.2 protein
EN
Cry1B.2 is a full-length, insecticidal protein consisting of 1187 amino acids with a molecular weight (MW) of 135 kDa. It is a chimeric protein that consists of domains I and II from Cry1Be, domain III from Cry1Ka2, and the
C-terminal domain from Cry1Ab from various subspecies of soil bacterium Bacillus thuringiensis. The production of the Cry1B.2 protein in soybean provides protection against lepidopteran 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.
