A TI{CRIMIC.TG4.0} DNA cassette has been inserted into CG31111, in a coding intron, and is predicted to gene trap all annotated transcripts of the gene. The TI{CRIMIC.TG4.0} 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: ATGTAAACATATATGTGAGTAGG. The CR71719 insertion is 323 bp upstream of the 5' end of the stac-RE transcript on the opposite strand from CG31111 and may affect the expression.
