A TI{CRIMIC.TG4.1} DNA cassette has been inserted into CG30087, in a coding intron, and is predicted to gene trap all annotated transcripts of the gene. The insertion is also within asRNA:CR44372, not in a coding intron, and it is not clear whether or not it acts to gene trap this gene. The TI{CRIMIC.TG4.1} cassette was inserted via the CRISPR/Cas-9 drop-in technique, using a dsDNA donor vector with homology arms of length 200bp. The sgRNA sequence used to target the gene was: TTTGTAGAAAGTATGGTAGAAGG.
