Phylogeny of the mouse N1, N2 and N3 domains, rat N1 domains and human N domains. NJ-tree of N domain nucleotide sequences on ClustalX alignments of corresponding amino acid sequences showing the evolution of mouse (Mmu) PSG N1, N2 and N3 domains in comparison with rat (Rho) N1 domains, human (Hsa) N domains and baboon (Pha) N domains. Alignments were bootstrapped 1000 times yielding the values shown for the main branches. The scale bar represents 0.1 nucleotide substitutions per site.
