This COVID-19 event has been created by a combination of computational inference (see https://reactome.org/documentation/inferred-events) from SARS-CoV-1 data and manual curation, as described in the summation for the overall SARS-CoV-2 infection pathway.

Based on studies in other coronaviruses, the final SARS-COV-2 ribonucleoprotein complex is predicted to be a hollow helical structure with an approximate diameter of 9-16nm, with the C-terminal domain of N protein forming the inner core and the N-terminal domain forming the outer surface (Neuman et al, 2006; Chen et al, 2007). Oliomerization of the N protein capsid coat is likely nucleated through both protein-RNA and protein-protein interactions by the first few N-protein dimers on the genomic RNA (Saikatendu et al, 2007; Chang et al, 2013; reviewed in Chang et al, 2014). Each N dimer may make contact with up to 7 bases of the RNA (reviewed in Chang et al, 2014).
