Figure 2.

Schematic representation of the intron-exon organization (A) and splice junction sequences (B) of the porcine B4GALNT2 gene. (A) Shaded boxes represent exon coding sequences numbered E1–E11. Open boxes correspond to untranslated sequences present in the cDNA. The size of each exon is indicated in base pairs above each box and the intron distances are indicated below between each exon. The primer pairs (1–26, see Table1) and amplified products used to analyze the genomic structure from a BAC clone are illustrated below the genomic structure as solid bars for products covering exon/intron boundaries and open bars for products spanning entire introns. The primer numbering corresponds to the primers listed in Table1. (B) The proximal splice donor and distal splice acceptor nucleotide sequences (upper case) for each exon are shown. Adjacent intervening intron sequences (lower case) are shown. Exon numbering corresponds to (A).
