Predicted transcription factor binding sites in sequence adjacent to the core HB binding region. A. HB has a region of context conservation extending from the core PBR downstream from the -1 to -9 base positions. Using the weak ln(P) cutoff score alignment, a PWM was generated of this region and subjected to a JASPAR alignment search (see Methods for details). B. The top 5 hits are shown with WebLogo representations of their PWMs. Of the 5, only su(H) and sd are expressed in the early embryo, with organ specific and weak ubiquitous expression respectively.
