Figure 5

Phylogenetic analysis of SM proteins from eukaryotes in the major sampled supergroups. This analysis shows that the four SM protein families robustly form separate clades as shown by the bold support values and denoted by the vertical bars to the right of each clade. Support values are given in the order of Bayesian posterior probabilities/ML bootstraps/ML corrected distance bootstraps. That each family encompasses all of the sampled eukaryotic diversity is illustrated by the colour-coded taxon names, which follow the scheme of Figure 4. Support values for all nodes supported by 0.95 posterior probability and 50% bootstrap support or better, are illustrated symbolically. This analysis demonstrates that the SM protein families are ubiquitously found in the sampled eukaryotes and their evolution likely pre-dates the last common eukaryotic ancestor.
