Neighbor-joining tree of Ets DNA binding domain amino acid sequences of
vertebrate PU.1 family transcription factors. This tree was constructed
by using the me tree program, using proportions of
differences as a distance measure and excluding gaps. This method finds
a phylogenetic tree and statistically similar trees likely to represent
a minimum total genetic difference (branch length) among the genes. The
value at each node represents the probability that that branch length
is not zero. GenBank accession nos.: mouse PU.1, L03215; human PU.1,
