Background
The SARS-CoV Nucleocapsid (N) protein is a structural component essential for viral RNA packaging and replication. It plays a key role in virus assembly and modulates host cell processes. Due to its strong immunogenicity, the N protein is widely used in serological assays and COVID-19 diagnostics, making it an important target for virology research and diagnostic reagent development.
Synonyms
N protein, SARS nucleoprotein, Coronavirus nucleocapsid protein
