A TI{SA-KozakGAL4} DNA cassette has been inserted into an intron in the 5'UTR of the CG9416 gene. This is designed to lead to the expression of GAL4 under the control of CG9416 regulatory sequences together with the truncation of the CG9416 transcript upstream of the coding exons. The sgRNA sequence used to target the gene was: GCGGGTCACCTAGAAGTCAGTGG. The PCR check gave the expected-sized band for the right flank and longer than expected band for the left flank. The right insertion site was verified by sequencing.
