Background: The novel strain SARS-CoV-2 of coronavirus diseases (COVID-19) became pandemic at the end of 2019 with an unprecedented global crisis by infecting around 11 million peo-ple in more than 200 countries. The condition has now been provoked by the demand, supply, and liquidity shocks that COVID-19 has attacked the lives of a vast population.
Objectives: Researchers are therefore trying to encode and understand the viral genome sequence along with various potential targets to explore the transmission mechanism and the mode of treatment for COVID-19. The important structural proteins such as nucleocapsid protein (N), membrane protein (M), an envelope protein (E), and spike protein (S) related to COVID-19 are discussed in this manu-script.
Methods: The topology of these various targets has been explored utilizing structure-based design and crystallographic studies.
Results: The literature reported that the N-protein processes the viral genome to the host cell during replication. The “N-terminal domain” and “C-terminal domain” contribute towards localization in the endoplasmic region and dimerization respectively. The M protein determines the shape of coronavirus and also assists the S protein to integrate with the Golgi-endoplasmic region complex leading to the stabilization of the virion. The smallest hydrophobic viroporin termed “E” takes part in morphogene-sis and pathogenesis during intracellular infection. The viral spike (S) protein attaches the cellular receptors and initiates virus-cell membrane fusions. The main protease in the proteolytic process dur-ing viral gene expression and replication has also been discussed.
Conclusion: Currently, there is no permanent cure and treatment of COVID-19 hence researchers are repurposing a suitable combination of drugs including antiviral, antimalarial, antiparasitic, and anti-bacterial, hypertensive receptor blockers, immunosuppressants, anti-arthritis drugs, including ayurve-dic formulations. In brief, it is justified that, for complete recovery, there is a need for deep and elabo-rate studies on genomic sequences and invading mechanisms in the host cell.
