  1. Mutations in N protein are associated with decreased IL-6 induction and human DDX21-mediated increased IL-4 production in Omicron. (v) Due to mutations, the stability of S, M, N, and E proteins decrease in the order: Omicron > Gamma > Delta > Wuhan. (vi) Stronger Spike-hACE2 binding in Omicron is associated with its increased transmissibility. However, the lowest stability of the Omicron Spike protein makes Spike-hACE2 interaction unstable for systemic infection and for causing severe disease. Finally (vii), the highest instability of Omicron E protein may also be associated with decreased viral maturation and low viral load leading to less severe disease and faster recovery. Our method may be used for other similar viruses, and these findings will contribute to the understanding of the dynamics of SARS-CoV-2 variants and the management of emerging variants.
