03-P126 New functions of the Lim-homeodomain transcription factor 2 (Lhx2) during cortical neurogenesis

ted embryo. Using the example of a Forkhead binding site, we will show that this approach allows detection of very limited changes in enhancer activity in a whole embryo and, in particular, makes possible the identification of repressor binding sites that are usually difficult to detect. We will also discuss the possible implications of the presence of this Forkhead repressor binding site on hindbrain patterning.
