Organism
Human respiratory syncytial virus B (strain B1)
Status
Reviewed - Annotation score: 2 out of 5 - Protein inferred from homologyi

Functioni

Encapsidates the genome, protecting it from nucleases. The nucleocapsid (NC) has a helical structure. The encapsidated genomic RNA is termed the NC and serves as template for transcription and replication. During replication, encapsidation by protein N is coupled to RNA synthesis and all replicative products are resistant to nucleases By similarity.

Interactioni

Subunit structurei

Homomultimerizes to form the nucleocapsid. Binds to viral genomic RNA. In nucleocapsid, interacts with the protein P and thereby positions the polymerase on the template. Interacts with protein M2-1; this interaction allows the association of nucleocapsid with the matrix protein, supposely to shut down virus transcriptase activity and initiate assembly and budding By similarity.
