Multiple alignment IRF4 protein sequences in different species. The sequences were aligned using the ClustalW method. Identical (*) and similar (: or .) residues are indicated; the predicted domains from SMART Server software have been indicated by colored boxes: the yellow denotes the DBD and the blue denotes the IAD. Five tryptophan (W) residues are boxed in red. The GenBank accession numbers of the genes are listed in Table 2
