Figure 2.

Representation of the feline APOBEC3 genomic region, portraying the detected A3 transcripts. Transcripts with translated exon (rectangles) and spliced-out introns (dotted lines) are indicated. Please note that the transcript for A3H comes in two versions: with complete exon 2 and further spliced exon 2, resulting in 5' truncation (Ex. H2 5'Δ). The mRNA for A3CH includes exon 4 of A3Cb in an additionally spliced version, 3' truncating the sequence one nucleotide before the stop codon (Ex. Cb4 3'Δ).
