FunctionNCAP_VSIVA Encapsidates the genome in a ratio of one N per nine ribonucleotides, protecting it from nucleases. The encapsidated genomic RNA is termed the NC and serves as template for transcription and replication. Replication is dependent on intracellular concentration of newly synthesized N, termed N(0), which corresponds to the protein not associated with RNA. In contrast, when associated with RNA, it is termed N. During replication, encapsidation by N(0) is coupled to RNA synthesis and all replicative products are resistant to nucleases (By similarity).

Publication Abstract from PubMedVesicular stomatitis virus is a negative-stranded RNA virus. Its nucleoprotein (N) binds the viral genomic RNA and is involved in multiple functions including transcription, replication, and assembly. We have determined a 2.9 angstrom structure of a complex containing 10 molecules of the N protein and 90 bases of RNA. The RNA is tightly sequestered in a cavity at the interface between two lobes of the N protein. This serves to protect the RNA in the absence of polynucleotide synthesis. For the RNA to be accessed, some conformational change in the N protein should be necessary.
