The RMCE cassette of the TI{CRIMIC.TG4.1}ukarCR70473-TG4.1 insertion has been replaced with a 'Double Header' (DH) trapping cassette (contains two independent trapping modules oriented in opposite directions). The insertion is in a coding intron of ukar (in the protein-trap orientation relative to the gene) and is predicted to trap the 1 of 3 annotated transcripts of the gene with a EGFP-FlAsH-StrepII-TEV-3xFlag multi-tag cassette.
