On the number of nucleoproteins in the assembly of coronaviruses: Consequences for COVID-19

The multifunctional nucleoproteins play important role in the life cycle of coronaviruses. The assessment of their quantities is of general interest for the assembly of virions and medical applications. The proliferating nucleoproteins induce the related (auto)immune response and via binding to host RNA affect various regulation mechanisms. In this report we briefly summarize and comment the available experimental data on the subject concerned.
