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 After mapping sequences to the SARS-CoV-2 reference genome (GenBank accession number MN908947.3), we found that there were two variants in the cell-isolated viral strain with deletions at (i) positions 23583 to 23597 (Var1), flanking the polybasic cleavage site, resulting in a QTQTN deletion in the spike protein (one amino acid before the polybasic cleavage site); and (ii) positions 23597 to 23617 (Var2), resulting in a NSPRRAR deletion that includes the polybasic cleavage site (Fig. 1A)
