nCoV N-Protein / Nucleocapsid protein is an RNA-binding protein primarily involved in binding to the viral RNA genome during packaging of viral RNA into a helical ribonucleoprotein or nucleocapsid structure (1). In addition, N-protein regulates viral RNA synthesis during replication/transcription and modulates host-pathogen interactions, such as actin reorganization, host cell cycle progression, and apoptosis (2). N-Protein is abundantly expressed during infection and antibodies against N-Protein have been detected in confirmed cases of Covid-19. Therefore, N-Protein is a potent antigen that provides basis for future vaccine and diagnostic kit development (3).
