  1. Myotubularin homologue sequences from human ("Hu") and Danio rerio ("Dr") were obtained from the literature and database keyword searches. For the other species represented, candidate myotubularin sequences were obtained by searching the protein datasets of fully sequenced eukaryotic genomes, as detailed in Methods. The prefix "N" or "Nv" followed by a numeral denotes sequences from Nematostella vectensis, "Tad" followed by a numeral denotes sequences from Trichoplax adhaerens, and "M" followed by a numeral denotes sequences from Monosiga brevicollis, (except "Mbrevi5R3" which is also from Monosiga). The sequences were aligned as detailed in Methods. Phylogenetic trees were inferred as detailed in Methods. Shown are the composition and clade support for the six similarity groups previously identified [2, 3]. The plus and minus symbols (+,-) indicate the presence of enzymatically active or inactive catalytic loop sequence signatures, respectively. For each group, the number above the line indicates the Bayesian clade support (posterior probability), and the number below the line indicates the bootstrap support (out of 100 total replicates) in Maximum Likelihood (ML). Results presented are the mean (± SD) of four distinct alignments.
  2. Sequences Tad51955 and M01745983 consistently clustered together as a distinct "new clade". The mean Bayesian posterior probability was: 0.998 (± 0.0005) (n = 4). The mean bootstrap support in Maximum Likelihood (ML) was: 97.5 (± 0.577) (n = 4).
  3. Sequences Nv82921, Tad62282 and MBrevi5R3 could not be placed into a similarity group with confidence.
