The ΔNp63α Phosphoprotein Binds the p21 and 14-3-3σ Promoters In Vivo and Has Transcriptional Repressor Activity That Is Reduced by Hay-Wells Syndrome-Derived Mutations

Abstract excerpt

p63 is a recently identified homolog of p53 that is found in the basal layer of several stratified epithelial tissues such as the epidermis, oral mucosa, prostate, and urogenital tract. Studies with p63(-/-) mice and analysis of several human autosomal-dominant disorders with germ line p63 mutations suggest p63 involvement in maintaining epidermal stem cell populations. The p63 gene encodes six splice variants...
