Although previous studies have highlighted the role of p63 triggering the epidermal transcriptomic program  its precise mechanism of target gene regulation in the complex context of a developing embryo remains poorly understood. Here  we used zebrafish embryos to analyze in vivo how p63 regulates the expression of its target genes during development. We generated tp63 knock out mutants that recapitulate human phenotypes and show down regulated epidermal gene expression. Following p63 binding dynamics during development  we found two distinct functions clearly separated in space and time. During early development  p63 binds enhancers associated to neural genes  where it limits Sox3 binding and reduces the expression of these neural genes. Indeed  we show that p63 and Sox3 are co expressed in the neural plate border. Later in development  p63 binds enhancers associated to epidermal genes and promotes their expression  acting as a pioneer factor  as it binds to non accessible chromatin and is required for its opening. Therefore  our results suggest that p63 is an important regulator of cell fate decisions during ectoderm specification  promoting the epidermal fate and inhibiting the neural program.
