mRNA splicing pattern. A, in αII^SV tryptase, recognition of a novel 3′ splice site within exon 4 results in shortening of exon 4. B, detail of intron 3/exon 4 splice site junctions for αII and αII^SV tryptase. C, nucleotide sequence alignment of intron 3/exon 4 splice site junctions for αII and αII^SV tryptase.
