The VT026999 enhancer fragment followed by the Drosophila synthetic core promoter (DSCP) is fused upstream of the p65(AD)::Zip+ hemidriver (component of a 'split driver' system, contains the p65 activation domain).
Comment: when combined with TI{2A-GAL4(DBD)::Zip-}NPFT2A-Gal4DBD (combination referred to as 'DAL2-split GAL4')
