It is a multi-isoform protein required for epidermal development[1]. p63 domains structure is similar to that of p53 with an N-terminal transactivation domain (TAD) followed by proline-rich region, DNA-binding domain (DBD) and tetramerization domain. In addition, the p63 contains an additional C-terminal region with SAM (Sterile a-Motif) and transactivation inhibitory domains. The SAM domain is involved in protein-protein interactions. Disease Mutations in p63 result in cleft lip or palate syndromes, split hand/foot malformation or ectodermal dysplasia[2], [3]. Relevance One isoform of p63 is involved in skin development and stem/progenitor cell regulation[4]. Another isoform functions in apoptosis[5]. Structural highlights . . .
