From: Phylogenetically widespread alternative splicing at unusual GYNGYN donors
Alternative splicing at the tandem donor of exon 21 of (a) human STAT3 and (b) mouse Stat3. Electropherograms are shown for direct sequencing of RT-PCR amplicons (e+i) and sequencing of isolated clones representing e and i transcripts (e and i, respectively). The cursor is positioned on the nucleotide upstream of the conserved GTAGTT motif. Numbers and ratios of clones representing e and i transcripts are given for human and mouse kidney (e:i).
