Homologs of p53 and a rudimentary phylogenetic tree. All the homologs of the p53 protein and a thumbnail of a phylogenetic tree constructed from their multiple alignment are shown. The thumbnail links to a bigger picture with more details, as explained in the next figure. The tree gives a rough idea of the phylogenetic relationships between the various proteins and identifies the proteins that need to be analysed further for understanding the evolution of this family.
