A TI{CRIMIC.TG4.1} DNA cassette has been inserted into DIP1, in a coding intron, and is predicted to gene trap all annotated transcripts of the 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: ACAAAGCACTAGGTTTCTTATGG. The PCR check gave the expected band for the left flank and a weak, longer than expected band for the right flank. The left flank was confirmed by sequencing.
