Large intron sizes in β2 genomic loci. Boxes denote the location of exons that encode the 5' region of β2 subunit genes. The intervening regions denote the relative sizes of introns, labeled in bp. The scale is expanded for the teleost gene diagrams relative to human. The various N-terminal (grey) exons splice to the solid black exon, which begins with amino acids GSAD...The following genomic contigs were used for the analysis: Human β2 (NT_008705.15), Danio β2.2 (NC_007113), Danio β2.1 (NC_007133), Tetraodon β2 (CAAE01015017.1), Fugu β2 (CAAB01000004.1), Gasterosteus β2 (AANH01005391.1, using the EST DW608729, which resembles zebrafish β2.2).
