Figure 4

Suboptimal splice sites might mediate the skipping of exon 7 in KIR2DL4, KIR2DL5, and KIR3DL2 transcripts. Exon 7 is indicated in gray boxes, whereas the BPS and PPT elements are indicated in blue and red boxes, respectively. The 3′ ss region (3′ ss and PPT) and the 5′ ss sequences of lineage III KIR genes, except for KIR2DL1/2, are used as consensus sequences. Dashes (-) indicate sequence identity with the consensus sequence. The splicing strength scores of the 3′ and 5′ splice sites are provided. The BPS and 3′ splice sites of exon 7 were identical, but variation was observed in the PPT and 5′ splice site.
