Figure 1 Ath5 Promoter Alignment and Characterization

(A) Proximal promoter region alignment of ath5 in various vertebrate species. Numbering indicates bases 5′ of the start codon.

(B, C) Transgenic medaka embryos at day four of development. (C) Cryosection and anti-GFP antibody staining of a transgenenic embryo representing the full Ath5 expression pattern. Note that the reporter is weakly expressed all over the mature retina and specifically enriched in the GCL and in a few other cells indicated by arrows. Complete absence of expression is observed in the distal part of the ciliary marginal zone as well as outside the eye. Nuclei are visualized by DAPI counterstaining. CMZ, ciliary marginal zone; GCL, ganglion cell layer; INL, inner nuclear layer; ONL outer nuclear layer; and OC, optic chiasm.

(D) Transactivation of Ath5 on its own promoter assayed by luciferase reporter transcription activity. Two-kilobase Ath5 promoter or its mutant forms generated by PCR introducing base changes into the two conserved binding motifs were used (see Table S3 for oligo sequences). Values on the x-axis are the quantity (in ng) of Ath5pCS2+ -expressing vector transfected. WT corresponds to the wild-type promoter, M and N are mutations of the first and second conserved e-boxes, respectively, without disrupting the e-box consensus sequence. H and P are mutations of the first and second conserved e-boxes, respectively, with disruption of the e-box consensus sequence. MN and HP are mutations in both e-boxes without and with disruption of both e-boxes, respectively (see Materials and Methods for details)
