Figure 1. Comparison of putative nuclear export sequences (NESs) in Ngn3 protein with consensus NES motifs and Ngn3 homologues of various species.

Figure 1

The putative NES2 sequence is well conserved in various species. In the consensus NES sequence, X indicates any amino acid and Ø indicates a hydrophobic residue, such as leucine, isoleucine, valine or methionine. Letters colored green correspond to amino acids that are not conserved in the species studied. Residues critical to NES activity are indicated by red letters.
