Movie S1

Proline locations indicated in 3D structure of importin β. A 3D rotation movie of importin β (PDB: 1ukl) molecule shown in a surface representation. 15 proline residues in A-helix are indicated in red.

Prolines in the α-helix confer the structural flexibility and functional integrity of importin-β
