NOL7 is composed of distinct biochemical domains and multiple putative NLSs that show evolutionary conservation. (A) Multiple sequential analysis programs confirmed the existence of four basic (blue) and one acidic (green) region in the full-length sequence of NOL7. Putative NLSs identified in sequence analysis programs are shown in red. (B) Sequence conservation between human NOL7 and its putative orthologs was analyzed for each of the putative NLSs and the alignment is shown. Black shaded boxes indicate identical amino acid conservation, while grey boxes signify similar amino acids to Homo sapiens. Numbers correspond to residues within the RefSeq sequences listed in the Materials and Methods 2.7.
