Nucleoprotein

UniProtKB accession:  P03521

Grouped By:  Matching UniProtKB accession

UniProtKB description:  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. Nucleocapsid assembly is concommitant with replication, therefore viral replication depends on the intracellular concentration of free N, termed N(0). All replicative products are resistant to nucleases.
