Determinants for RNA-binding specificity. (A, top panel) EMSA of the binding of the wild-type (WT) and indicated mutants of G5N to the 13-mer U4 fragment used for obtaining the cocrystal structure. A 2:1 protein to RNA molar ratio was used in the assay. (Middle panel) Binding of G5N and its mutants to in vitro transcribed full-length U4 snRNA. (Bottom panel) G5N and its mutants used for EMSA experiments. (BE) FP measurements of binding affinities of the wild-type and mutant G5N proteins to the 13-mer RNA. The derived dissociation constant (KD) values are shown.
