CC   -!- FUNCTION: Encapsidates the genome in a ratio of one protein N per nine
CC       ribonucleotides, protecting it from nucleases. If expressed without
CC       protein P it binds non-specifically RNA and therefore can bind it's own
CC       mRNA. Interaction with protein P abolishes any non-specific RNA
CC       binding, and prevents phosphorylation. The soluble N-P complex
CC       encapsidates specifically the genomic RNA, with protein N protecting
CC       the genome like a pearl necklace. The encapsidated genomic RNA is
CC       termed the nucleocapsid (NC) and serves as template for viral
CC       transcription and replication. Protein N binds protein P in the NC
CC       through a different interaction, and can be phosphorylated. Subsequent
CC       viral replication is dependent on intracellular concentration of newly
CC       synthesized protein N. During replication, encapsidation by protein N
CC       is coupled to RNA synthesis and all replicative products are resistant
CC       to nucleases (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Homomultimerizes to form the nucleocapsid. Binds to viral
CC       genomic RNA. In nucleocapsid, binds protein P and thereby positions the
CC       polymerase on the template. Protein P acts as a chaperone on free
CC       protein N to prevent it from aggregation before encapsidating genomic
CC       RNA (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion. Host cytoplasm {ECO:0000250}.
CC   -!- PTM: Phosphorylated by host CK2. Unphosphorylated protein N seems to
CC       have a better affinity for leader viral promoter encapsidation.
CC       Phosphorylation of protein N in ribonucleocapsid may stabilize the
CC       interaction with protein P, thereby playing an important role in viral
CC       transcription/replication (By similarity). {ECO:0000250}.
CC   -!- MISCELLANEOUS: Displays a superantigen activity in human and mouse,
CC       activating mostly V-beta-8 subtypes of T-cell receptor. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the lyssavirus nucleocapsid protein family.
CC       {ECO:0000305}.
