Fig. 2. Chromatin immunoprecipitation of neuralized murine EBs. (A-H)
Selected positive targets showing the mean fold enrichment of
Gli1FLAG ChIPs representing three biological replicates, each with
four technical replicates. The plots show the mean fold enrichment of ChIPed
sequence versus input. Approximately half of the peaks lie outside the
proximal promoter region. Multiple peaks are numbered to correspond to the
peaks listed in Table 1 and in
Table S2 in the supplementary material; arrows indicate previously described
Gli regulatory regions. Below each graph, the position of exons (rectangles)
and the direction transcription (arrows) are shown relative to the ChIPed
region. (I,J) De novo motif analysis recovers a consensus site
(I) similar to a previously described Gli1 consensus sequence (J) (Transfac #
M01037) (I).
