  • Background

    The single-stranded, plus-sense severe acute respiratory syndrome coronavirus 2 (SARS–CoV-2) genome encodes nonstructural replicase polyproteins as well as structural proteins such as spike (S), nucleocapsid (N), membrane (M) and envelop (E) proteins (Zhou et al., 2020). The N protein is abundantly expressed and highly immunogenic during SARS-CoV-2 infection (Cong et al., 2020). The middle or C-terminal region of the N protein has been shown to elicit antibody production during the immune response (Dutta et al., 2020). Although the surface electrostatic potential characteristics of SARS-CoV-2 N are different from other coronavirus N proteins (Kang et al., 2020), the sequences are conserved among these proteins (Dutta et al., 2020). Besides S protein, N protein is also considered a leading target antigen for vaccine development (Chen et al., 2020; Dutta et al., 2020).
