Dendrogram of ZnT proteins. Bootstrapping (2000 replicate sets) and calculation of the consensus tree by the neighbour-joining method were performed with the DAMBE program. The numbers indicate bootstrapping values as a percentage at internal nodes. The scale of the branch length is given in amino acid substitutions per site. Accession numbers in Entrez databanks are indicated for protein sequences excepted for ZnT-10 whose accession number corresponds to the cDNA sequence. Zip-2 protein sequence was used as an outgroup.
