The SARS-CoV-2 nucleocapsid protein also known as N protein plays a central role in the packaging and replication of the viral RNA genome. It functions mechanically by binding to the viral RNA to facilitate its replication and encapsidation. The nucleocapsid protein is expressed within the virus-infected cells particularly in the cytoplasm. It is a highly conserved structural protein of the virus and has a molecular weight of approximately 50 kDa. Additionally the nucleocapsid protein aids in RNA binding and is essential for the virus's structural stability.

Biological function summary

The nucleocapsid protein of SARS-CoV-2 is involved in maintaining the integrity of the viral genome. It forms a ribonucleoprotein complex with the viral RNA which is necessary for viral replication. The nucleocapsid protein is integral in the formation of the virus's structure and assists in the assembly and release of new virus particles. It interacts with other viral proteins contributing to the stability and functioning of the virus.

Pathways

The nucleocapsid protein is involved in the viral life cycle and replication pathways. The protein participates in the RNA replication and transcription complex working alongside proteins such as the RNA-dependent RNA polymerase and other non-structural proteins. These interactions within the pathways are essential for the efficient replication of the viral genome and production of new viral particles which are key steps in the virus's lifecycle.

The nucleocapsid protein is directly linked to COVID-19 the disease caused by the SARS-CoV-2 virus. It is a target for various diagnostic tests such as the COVID ELISA test and corona IgA test due to its immunogenic properties. The presence of nucleocapsid antibodies in patients is often measured through tests like the ELISA test which helps in diagnosing COVID-19. The nucleocapsid protein's involvement in COVID-19 progression connects it with other viral proteins highlighting its significance in disease mechanisms and potential therapeutic targeting.

Target data

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 (PubMed : 33264373). Plays an important role in enhancing the efficiency of subgenomic viral RNA transcription as well as viral replication. Attenuates the stress granules formation by reducing host G3BP1 access to host mRNAs under stress conditions (PubMed : 34901782, PubMed : 36534661).. May block host chemokine function in vivo, facilitating viral replication and transmission (PubMed : 35921414). Acts by being secreted into the extracellular space where it competes to host chemokines for binding to host glycosaminoglycans (GAG) (PubMed : 35921414).. May induce inflammasome responses in cultured cells and mice. Acts by interacting with host NLRP3 to facilitate inflammasome assembly, which induces cytokine release that may play a role in COVID lung injury.
