CC   -!- FUNCTION: Encapsidates the genome, protecting it from nucleases. If
CC       expressed without protein P it binds non-specifically RNA and therefore
CC       can bind it's own mRNA. Interaction with protein P abolishes any non-
CC       specific RNA binding, and prevents phosphorylation. The soluble N-P
CC       complex encapsidates specifically the genomic RNA, with protein N
CC       protecting the genome like a pearl necklace. The encapsidated genomic
CC       RNA is 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 (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion. Host cytoplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the novirhabdovirus nucleocapsid protein family.
CC       {ECO:0000305}.
