Phylogenetic analysis of human and mouse S100 proteins A neighbour-joining tree of human (Hs) and mouse (Mm) S100 proteins (1 through 15) was constructed using the Poisson correction model and the bootstrap percentage from 1000 replicates is indicated at each node. Results are consistent with the human S100A7 duplications (blue sub-tree) occurring after the divergence of mouse and human in evolution (red node).
