Figure 4From: Phylogenetic analysis of the SAP30 family of transcriptional regulators reveals functional divergence in the domain that binds the nuclear matrixA phylogenetic tree of the SAP30 family in which branch lengths are proportional to the extent of sequence divergence. The black arrow points to the tip of the animal branch, which is shown magnified in the lower left corner. The dispersed, monophyletic tetrapodan/sarcopterygian SAP30 group is shaded.Back to article page
