Phylogenetic relationships of 14-3-3s. This tree is a rooted cladogram from a neighbor-joining analysis  of the 133 different full-length 14-3-3 isoforms that are currently available in the GenBank database , with Dictyostelium discoideum 14-3-3 as the outgroup. Arabidopsis isoforms are highlighted in green. The separation of plant epsilon and non-epsilon 14-3-3 proteins is clearly visible.
