Alignment of the amino acid sequences of the TA domains of NFI-X3. Sequences were aligned with the ClustalW program. Dashes, gaps introduced to maximize the similarity; light gray boxes, identical sequences; dark gray boxes, sequences that are similar. The full-length sequence of human NFI-X3 was deposited into GenBankTM (FJ861276). The following sequences were aligned: Macaca fasicularis (AB172261), Macaca mulatta (XM_001110545), Canis familiaris (XM_542036), Xenopus laevis (52), Homo sapiens (AAD38241), Mus musculus (NM_001081981), and Rattus norvegicus (EDL92203).
