Inserting an intron in the PTM coding unit results in a significant improvement in trans-splicing efficiency. The two PTMs shown in the panel above the histogram are identical, except that CF-PTM59 has a 543-bp CFTR mini-intron 9 in the LacZ coding unit. The 3′ LacZ exon in CF-PTM59 is 124 bp long. Values are mean ± standard error of two separate experiments. (BD) Binding domain.
