A TI{KozakGAL4} DNA cassette has been inserted into CG30022, replacing the coding sequence (coordinates of deleted sequence are 2R:11387270..11388462 , release 6 genome). This results in a simultaneous knock-out of CG30022 plus a knock-in of GAL4 that is expected to be expressed under the control of the endogenous regulatory sequences of CG30022 (predicted to gene trap all annotated transcripts of the gene). The insertion is also within sprt and is not predicted to gene trap this gene. 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: ATAATCGAGTATCGCATTCAAGG and CGGGGTGTACGATATACCCAAGG.
