AstC regulatory sequences are fused upstream of the Drosophila Synthetic Core Promoter (DSCP) followed by sequence encoding the GAL4(DBD)::Zip- hemidriver.
An approximately 1kb fragment from the AstC locus (from upstream of the coding sequence) is fused upstream of the Drosophila Synthetic Core Promoter (DSCP) followed by sequence encoding the p65(AD)::Zip+ hemidriver.
