Cry1B.34.1 is a chimeric protein composed of modified sequences derived from two Bacillus thuringiensis genes: a cry1B-class gene and cry1Ca1. 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.

The Cry1B.34.1 protein is a truncated form of the full-length Cry1B.34 protein expressed in corn event DP910521.
