In this chapter we detail various experimental approaches to characterize the fuzziness of complexes made of the C-terminal domain of the nucleoprotein (NTAIL) from three representative paramyxoviruses and of the C-terminal X domain (XD) of the homologous phosphoprotein. We discuss the advantages, the limitations, as well as the caveats of the various methods. We describe experimental data showing that paramyxoviral NTAIL-XD complexes are characterized by a considerable amount of conformational heterogeneity. We also detail recent data that revealed that NTAIL is highly malleable, i.e., it displays a partner-mediated polymorphism. All the results suggest that NTAIL plasticity and fuzziness play a role in the coordination and regulation of the NTAIL interaction network so as to ensure efficient transcription and replication.

Abstract
In this chapter we detail various experimental approaches to characterize the fuzziness of complexes made of the C-terminal domain of the nucleoprotein (NTAIL) from three representative paramyxoviruses and of the C-terminal X domain (XD) of the homologous phosphoprotein. We discuss the advantages, the limitations, as well as the caveats of the various methods. We describe experimental data showing that paramyxoviral NTAIL-XD complexes are characterized by a considerable amount of conformational heterogeneity. We also detail recent data that revealed that NTAIL is highly malleable, i.e., it displays a partner-mediated polymorphism. All the results suggest that NTAIL plasticity and fuzziness play a role in the coordination and regulation of the NTAIL interaction network so as to ensure efficient transcription and replication.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
