A TI{KozakGAL4} DNA cassette has been inserted into ICA69, replacing the coding sequence (coordinates of deleted sequence are 3L:21131743..21133214 , release 6 genome). This results in a simultaneous knock-out of ICA69 plus a knock-in of GAL4 that is expected to be expressed under the control of the endogenous regulatory sequences of ICA69 (predicted to gene trap all annotated transcripts of the 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: CCTCCTAAACAACCACTCAGTGG and TTTGACTAGCTAGTTTCCAACGG.
