A: Secondary structure of PSRPK NLS, as predicted by DNASIS v2.5 Demo. The capital H, S and T blow the sequence represent the corresponding amino acid above has more probability to form helix, sheet or turn. B: The overall structure of PSRPK that mimics the structures of SRPK1 and Sky1p, as predicted by SWISS-MODEL online and displayed by SWISS-Pdb viewer compared with the overall structure of SRPK1 and Sky1p [17–20]. C: NLS, the NLS of PSRPK; NLSd, the NLS of PSRPK without 318PKKGDK323; NLSm, the NLS of PSRPK with the K320 → T320 mutation.
