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}.
