FIG. 3.
PCBP2 and PTB binding to the murine norovirus 3′ end. EMSAs demonstrated the ability of recombinant PCBP2 and PTB to interact with the wild-type MNV 3′ end (A and D, respectively) or the SL3 GNRA 3′ end (B and E, respectively). Quantification of the corresponding EMSA products is expressed as the percentage of probe in any complex with either recombinant PCBP2 (C) or PTB (F). The positions of the free probe (P) and various RNA-protein complexes (C, CI, CII, and CIII) are also highlighted.
