Figure 1.
Genomic organization of PRL gene. (A) Comparison of the structures of vertebrate PRL genes. The grass carp PRL gene was aligned with that human, chicken, frog (xenopus) and goldfish homologous with respect to the ATG translation start codon at the 3′-end of exon 1. Boxes and lines represent exons and introns, respectively. The scale bar at the bottom represents the distance in kb with respect to the translation start codon ATG. (B) DNA sequences at the intron/exon junctions in different PRL genes. Exon sequences are shown in capital letters and the intron sequences are shown in lower case. The consensus intron splice donor and acceptor sequences are shown in italics.
