Nucleoprotein

UniProtKB accession:  P26590

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Forms the helical nucleocapsid (NC) in a ratio of 1 N per 6 ribonucleotides, protecting the genome from nucleases (By similarity). The encapsidated genomic RNA serves as template for transcription and replication; encapsidation by N is coupled to RNA synthesis. Forms the encapsidation complex with the phosphoprotein protein P. Before encapsidation, the newly synthesized free N protein, so-called N0, is chaperoned by P (By similarity).
