A TI{KozakGAL4} DNA cassette has been inserted into ATPsynCF6, replacing the coding sequence (coordinates of deleted sequence are 3R:23355294..23355784 , release 6 genome). The entire 5'UTR of ATPsynCF6 is deleted and it is uncertain whether GAL4 is expressed. The TI{KozakGAL4} cassette was inserted via the CRISPR/Cas-9 drop-in technique, using a dsDNA donor vector with homology arms of length 200bp. The sgRNA sequences used to target the gene were: GCAGGGATTGCGACAGCATCTGG and ACAAAAAAAACCAATAAAATCGG.
