UniProtKB description:  Plays critical roles in regulating RNA replication and transcription through its interactions with multiple proteins (PubMed:25568210, PubMed:26474524). Tethers the RNA-directed RNA polymerase L to the nucleoprotein-RNA complex (PubMed:26474524). Recruits the M2-1 protein, a processivity factor that is required for efficient transcription of viral RNA (PubMed:26474524). Acts as a chaperone for neo-synthesized nucleoprotein by forming an N-P complex that preserves N in a monomeric and RNA-free state and prevents the association of nascent N with host cell RNAs (PubMed:25568210). Recruits the host phosphatase PP1 to inclusion bodies to regulate viral transcription (PubMed:29489893). Together with the nucleoprotein, sequesters host NF-kappa-B in inclusion bodies (IBs) thereby inhibiting this host defense pathway (By similarity).
