Figure 4.

Amino acid sequence alignments of the putative FIM and DXS6673E (34) proteins. Gray boxes represent identities and gray letters conservative substitutions. Double arrows represent the cysteine-rich motifs with the consensus C-X2-C-X_18–24-F/Y-C-X3-C sequence, which may correspond to putative zing finger motifs whereas the dotted double arrow shows a nonconsensus motif in the FIM sequence. The stretch of hydrophobic, proline-rich residues is underlined. ▴, Potential bipartite nuclear localization signal.
