Functioni

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

Domaini

This protein can be divided into a hydrophobic N-terminal half, and a hydrophilic and highly acidic C-terminal half.By similarity
The coiled coil region is critical for homooligomerization, for the interaction with VP35 and for NP function in RNA synthesis.
Late-budding domains (L domains) are short sequence motifs essential for viral particle budding. They recruit proteins of the host ESCRT machinery (Endosomal Sorting Complex Required for Transport) or ESCRT-associated proteins. Nucleoprotein contains one L domain: a PTAP/PSAP motif, which interacts with the UEV domain of TSG101.
