Maximum likelihood analysis of mammalian p53 indicates the presence of positively selected sites and higher tumorigenic mutations in purifying sites
The tumor suppressor gene TP53 (p53) maintains genome stability. Mutation or loss of p53 is found in most cancers. Analysis of evolutionary constrains and p53 mutations reveal important sites for concomitant functional studies. In this study, phylogenetic analyses of the coding sequences of p53 from 26 mammals were carried out by applying a maximum likelihood method. The results display two branch
