Component
Use(s)
Regulatory region(s)
GMR31H09
Encoded product / tool
GAL4(DBD)::Zip-
Description

The R31H09 enhancer fragment is fused upstream of the Drosophila synthetic core promoter (DSCP) followed by the GAL4(DBD)::Zip- hemidriver (component of the 'Split GAL4' system, contains the GAL4 DNA-binding domain). A Hsp70 transcriptional terminator is present.

p65(AD)::Zip+
Description

The R21A05 enhancer fragment is fused upstream of the Drosophila synthetic core promoter (DSCP) followed by the p65(AD)::Zip+ hemidriver (component of a 'split driver' system, contains the p65 activation domain). A Hsp70 transcriptional terminator is present.
