SmVAL6 genomic structure analysis reveals a highly complex gene composed of 38 exons. SmVAL6 exons are represented by boxes, with exon length (in base pairs) given above each box. Introns are represented by lines, with intron length (in base pairs) shown below each line. Exons are coloured to indicate: SCP/TAPS domain (red), untranslated region (white) and remaining ORF (blue). Each successive exon has been ascribed a number (underlined numbers below the exons). Exons that introduce a premature stop codon are highlighted with an asterisk and dashed lines represent separate exons created by competing 3' splice sites. The exon specific annealing positions of primers VAL6 var F and VAL6 var R, used for developmentally-regulated alternative splicing analysis, are indicated.
