Figure 9. A model for FrAdV1 Pre-pVII nuclear import.Schematic representation of FrAdV1 Pre-pVII and its targeting sequences. The protein is represented by a white horizontal bar . NLSs are shown as blue vertical bars , along with their amino acidic sequence. The single letter amino acid code is used. Basic residues are in boldface . NLS: nuclear localization signal; cNLS: classical NLS; ncNLS: non classical NLS; NoLS: nucleolar localization signal.
