Genomic and complementary DNA and protein isoforms of the zebrafish GR. The zebrafish (z) GR gene consists of nine exons. The zGR gene expresses zGRα and zGRβ splicing variants through intron retention [32]. C-terminal gray colored and shaded domains in zGRα and zGRβ show their specific portions. They are, respectively, encoded by exon 9 and the 3′ portion of exon 8, which are also shown in the same labeling.
