| Immune escape mutation | Yes |
| Immune escape mechanism | The results showed that that key residues (Y449A, Y453A, F456A, A475W, Y489A, and Q493W) were critical for the complex and presumably, alterations in the packing caused marked loss of binding affinity (Fig. 2b and Supplementary Fig. 2b). |

Protein detail:
| Protein name | Spike glycoprotein |
| Uniprot protein ID | P0DTC2 |
| Protein length | 1273 amino acids |
| Protein description | Spike protein is one of the structural proteins of SARS-CoV-2. The monomeric protein consists of one large ectodomain, a single-pass transmembrane anchor, and a short intracellular tail at C-terminus. It encompasses 22 glycosylation sites. S protein cleaves into two subunits namely S1 and S2 following receptor recognition. Receptor Binding Domain (RBD) in S1 subunit plays a major role in ACE2 receptor binding. |
