A TI{CRIMIC.TG4.1} DNA cassette has been inserted into cac, in a coding intron, and is predicted to gene trap a subset of the annotated transcripts of the gene (predicted to trap ten phase 1 intron transcripts and not to trap five phase 2 intron transcripts). 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: GGGTATAAGTATATAACTGGAGG.
