Characterization of PCTD residues involved in the interaction with the N-RNA complex. Shown are data for SDS-PAGE analysis after Coomassie blue staining of the products of copurification between GST-P[231–241] mutant proteins and N-His (left) and a summary of the interactions (right). P[231–241] residues critical for the interaction with N are shown in boldface type in the amino acid sequence.
