Fig. 2. The Kapβ2•Nab2PY-NLS Interface.

Fig. 2

(A) The Nab2PY-NLS (cyan) makes numerous hydrophobic contacts with Kapβ2 (pink). In addition, Arg-235 of the Nab2PY-NLS makes multiple salt bridges and hydrogen bonds with Kapβ2. Interacting residues on Kapβ2 are labeled in black and contacts (4.0 Å or less) are indicated by dashed lines. (B) Comparison of the PY motifs of PY-NLSs from Nab2 (cyan) and hnRNP D (orange). Intramolecular contacts (4.0 Å or less) in hnRNP D are shown with dashed lines.
