Figure 3.
Highly conserved noncoding vertebrate sequences. Stars indicate identical nucleotides. (A) A stretch of ∼240 bp at the 3′ end of wnt1 is 68% homologous between mouse andFugu. Homeodomain binding sites HBS1 and HBS2 (Iler et al. 1995) are labeled. (B) Extremely high conservation of the 5′ wnt1 noncoding region of Fugu and zebrafish (Danio rerio). The core sequence of 187 bp shows 85% identity in both species. Base pairs are counted from the translation start sites. (C) Region of homology 5′ of human and Fugu ARF3.
