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. |

| Title | Variant analysis of SARS-CoV-2 genomes in the Middle East |
| Author | Khalid Mubarak Bindaynaa, Shane Crinionb |
| Evidence | We identified 2200 distinct genome variants which are recorded in Table 1 . The most common, high impact variants were 10818delTinsG, 2772delCinsC, 14159delCinsC and 2789delAinsA. The frequency of each unique variant type can be found in Table 2 , which outlines the locus of all SNPs with over 50 instances. |
