Figure 4From: Evolutionary relationships of Aurora kinases: Implications for model organism studies and the development of anti-cancer drugsUnrooted phylogenetic tree of Aurora kinases from human and model organisms. Tree was constructed using the maximum likelihood quartet puzzling method [43]. Scale bar represents 0.1 expected amino acid residue substitutions per site. Confidence estimates of nodes, fonts, and colours of species names correspond to Fig. 2.Back to article page
