Fig. 1. A map of the eve locus is shown at the top. The positions of five
enhancers that control early stripe formation (1-7) are shown. Two other
enhancers that control the refinement of the initial stripes (LE), and later
expression in inter-stripe regions (ftz-like) are also indicated. A
map of the eve 2 minimal stripe element (MSE) is shown in the middle
with positions of defined binding sites for transcription factors. Activator
and repressor sites are closely linked, especially in two clusters, each of
which contains two pairs of overlapping sites. Regions tested by deletion
analyses are marked (D1-D5). A model for eve 2 regulation is
presented at the bottom. Activation is mediated by Bcd and Hb, while Gt and Kr
are involved in repression mechanisms that form the stripe borders.
