Expression of GFP under the ΔNp63 promoter. Antibody staining of 5.5dpf tg(ΔNp63::Gal4,UAS::GFP) zebrafish larvae using anti Cytokeratin (red) and anti GFP antibody (green). The co-labeling of both antibodies reveals activity of the 4.96 kb upstream promoter element of ΔNp63 exclusively in basal epidermal cells in the skin.
