The domain structure of the p53 family proteins. (A) The domain organization of human p53, p63, and p73 along with the p63/p73 ancestor proteins from Drosophila melanogaster and Caenorhabditis elegans. The percentage of identity of the amino acids and their position in the domain are given for both the DNA-binding domain and the oligomeric domain. (B) The structure of the oligomeric domain of p73 from ref. . The H-2 helix stabilizes this p73 tetramer and is absent from the p53 tetramer. p63 and p73 are more closely related to each other than to p53 based on the primary, secondary, tertiary, and quaternary structures of both the DNA-binding domains and the oligomerization domains.
