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. |

| Evidence | We then analyzed a series of NTD mutants in which amino acid residues structurally close to R214 or K187 were mutated to alanine and found that binding of enhancing antibodies to the NTD was substantially decreased in W64A, H66A, K187A, V213A, and R214A mutants (Figure 4B). |
