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. |
