The phylogeny of the vertebrate Dispanins ( Figure 1 ) allows the division of the Dispanins into four subfamilies A-D that are supported by strong confidence with respect to posterior probabilities (pp) or bootstraps (pp.0.75 and bs.90% for all nodes). We propose a common nomenclature for the Dispanins that are based on their subclass and a number (DSPA1 etc). The proposed names together with previous gene symbols and accession number can be found in Table S1 .
