The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of the coronavirus induced disease 19 (COVID-19) which emerged in China in late 2019, resulting in a worldwide epidemic (Zhou et al., 2020). SARS-CoV-2 is an enveloped positive-sense single-stranded RNA virus with a number of important structural proteins, including the envelope (E) protein, the membrane (M), the spike (S) protein, and the nucleoprotein (N). Nucleoproteins, also known as nucleocapsid proteins, are phosphoproteins that are capable of binding to helix and have flexible structure of viral genomic RNA. It plays an important role in virion structure, replication and transcription of coronaviruses, as it localizes in both the replication/ transcriptional region of the coronaviruses and the ERGIC region where the virus is collected. It packages the positive strand viral genome RNA into a helical ribonucleocapsid (RNP) and plays a fundamental role during virion assembly through its interactions with the viral genome and membrane protein M. It also plays an important role in enhancing the efficiency of subgenomic viral RNA transcription as well as viral replication. There is structural similarity between porcine reproductive and respiratory syndrome virus (PRRSV), a member of Arteriviridae, suggesting a common origin for Coronaviridae and Arteriviridae nucleoproteins (Yu et al., 2006).
The Native Antigens monoclonal antibodies against SARS-CoV-2 nucleoprotein have been manufactured for the development of improved diagnostic assays for COVID-19.
