Figure 1

A phylogenetic tree for proteins of the FoxE subclass and the FoxC and FoxD outgroups. A neighbor-joining method was used to construct the tree topology and bootstrapping values are shown at each branch point (percentage of 1000 bootstrap samples) using the MEGA 3.1 software. Gaps were deleted in pairwise comparisons. The distance scale below the tree represents the number of substitutions per site. The C and D families are collapsed for better illustration. Protein sequences that lack a recognizable eh1-like motif are represented by blue triangles. Proteins and subclasses that contain an eh1-like motif are represented by red circles.
