Figure 3From: The evolution of protostome GATA factors: Molecular phylogenetics, synteny, and intron/exon structure reveal orthologous relationshipsIntron/exon Structure of arthropod GATA conserved domains. Schematics of the exon structure for the conserved dual-zinc finger domain of the arthropods GATA transcription factors. The ancestral prototype for this conserved domain consists of three exons with well-conserved boundaries, represented here by the sole Nematostella vectensis NvecGATA. The first exon (ZF1 in yellow) consists of the first DNA binding zinc-finger, whereas the second (ZF2 in green) contains the second DNA binding zinc-finger domain. The third exon (3'CD in blue) contains the GATA N-terminal activation domain described for some species.Back to article page
