A TI{CRIMIC.TG4.0} DNA cassette has been inserted into mino, in a coding intron, and is predicted to gene trap all annotated transcripts of the gene. In addition, the five coding exons of mino downstream of the inserted gene trap cassette have been deleted. The TI{CRIMIC.TG4.0} cassette was inserted via the CRISPR/Cas-9 hybrid technique, using two gRNAs that target mino : one targeted to a coding intron (ACCTAAGGGGATGCAGTTCAAGG) and the other to a non-coding exon in the 3' UTR (AAGTGGATATGCACTATACAAGG).
