Abstract

Since the emergence of SARS-CoV in 2003, researchers worldwide have been toiling away at deciphering this virus's biological intricacies. In line with other known coronaviruses, the nucleocapsid (N) protein is an important structural component of SARS-CoV. As a result, much emphasis has been placed on characterizing this protein. Independent research conducted by a variety of laboratories has clearly demonstrated the primary function of this protein, which is to encapsidate the viral genome. Furthermore, various accounts indicate that this particular protein disrupts diverse intracellular pathways. Such observations imply its vital role in regulating the virus as well. The opening segment of this review will expound upon these distinct characteristics succinctly exhibited by the N protein. Additionally, it has been suggested that the N protein possesses diagnostic and vaccine capabilities when dealing with SARS-CoV. In light of this fact, we will be reviewing some recent headway in the use cases for N protein toward clinical purposes within this article's concluding segments. This forward movement pertains to both developments of COVID-19-oriented therapeutic targets as well as diagnostic measures. The strides made by medical researchers offer encouragement, knowing they are heading toward a brighter future combating global pandemic situations such as these.
