Fig. 3 Two promoter fragments, E1 and E2, contain putative Soxbinding
sites and can drive gastrula-stage expression in the endoderm.
The position of the two Pst1/Spe1 fragments, E1 and E2, are
shown at the top. Their expression in partial transgenics is shown
below, using GFP fluorescence and in situ hybridization to GFP
mRNA in different embryos. On the right are shown the sequences
of E and E2, indicating Sox-binding sites (yellow boxes, contained
the core sequence ACAAT), Smad sites (green), FAST-1 sites (blue),
and GATA sites (red). The three Sox sites in E2, of which the central
one is a complex of three overlapping sites, are labelled A–C. Image published in: Ahmed N et al. (2004) Copyright © 2004. Image reproduced with permission of the publisher and the copyright holder.
