Characteristics of first exons of porcine GR.

<p>(A) Locations of the 3′ boundary of the porcine alternative first exons of porcine GR. (B) Map of the alternative first exons of the porcine GR gene and their human and rat homologues. Experimentally identified exons are shown in solid line boxes and the predicted human GR exon 1-G is shown in dotted box. The size of the exons shown is not to scale. Length of each exon is shown in the respective box in base pairs, and the numbers in between represent the percentage homology of respective exons in comparison with the human homologue.
