Fig. 5: N protein phosphorylation weakens RNA binding affinity.

a Quantification of binding affinity between N vs. pN and the viral stem loop 4 RNA (SL4) based on a change in normalized fluorescence polarization (minimum polarization set to 0). Data presented as mean values ± SD, n = 3 independent trials. b Quantification of binding affinity between N vs. pN and unstructured 30-base polyrA from normalized fluorescence polarization. Data presented as mean values ± SD, n = 3 independent trials. Source data are provided as a Source Data file.
