A 2381 base pair fragment from the flanking non-coding or intronic region of Ggamma30A is fused upstream of a Drosophila core synthetic promoter (DSCP) followed by sequence encoding a lexA::p65 driver. The driver sequence has been optimized for Drosophila codon usage. An Hsp70 transcriptional terminator is present.
EcollexAGMR12D09 expression mostly, but not completely, overlaps with that of ScerGAL4VT032906 and ScerGAL4VT020739.
