Abstract：
:The tumor-suppressor protein p53 belongs to a small gene family that includes p63 and p73. While p53 and p73 regulate cell cycle progression and apoptosis, the major role of p63 appears to be in promoting ectodermal proliferation and differentiation. In this report we describe the cloning of a Xenopus orthologue of mammalian p63 that is extraordinarily conserved in sequence. The major sites of expression of Xenopus p63 mRNA are the epidermis and some neural crest and crest derivatives such as the branchial arches and tail fin. Expression is also observed in the neural plate and in the stomodeal-hypophyseal anlage. Antibodies against p63 detect a nuclear protein that is distributed in a manner similar to that of Xp63 mRNA. Both mRNA and protein are conspicuously absent from regions of the epidermal sensorial layer that are induced to form a number of (but not all) ectodermal placodes and Xp63 protein levels are particularly dynamic in the epidermis of the eye as the lens forms.
