Characterization of porcine BCL2L2-PABPN1 (BP). (A) Genomic and mRNA structure of porcine BP. Boxes and lines indicate exons and introns, respectively. Dotted boxes in PABPN1 indicate that the sequences are first obtained here. Figures over the boxes indicate the length of the corresponding exons, while those in the boxes indicate exon No. Primer locations are shown with arrows. E, exon. I, intron. # indicates the position of poly(A) signal. Start and stop codons are shown under the boxes. (B) Motifs in the polypeptide of BP. (C) Identification of mechanisms underlying BP formation with RT-PCR. Templates were showed below. No RT, no reverse transcriptase control.
