Protein detail:
| Protein name | ORF7b |
| Uniprot protein ID | - |
| Protein length | 43 amino acids |
| Protein description | ORF7b encodes a viral accessory protein. Based on its similarity to other coronavirus proteins, ORF7b protein is thought to localize to the Golgi compartment. The orf7b is a hydrophobic protein with a transmembrane domain N-terminal at the outside, and a cytoplasmic C-terminal. Similar to orf7a, orf7b is reported by the majority of the previous studies that it is not essential for virus replication. |

| Evidence | We examined mutations in 383,570 complete sequences with known sampling dates in GISAID up until January 20, 2021. Figure 1 shows the worldwide distribution of Spike mutations as well as other variants of interest over time from April 2020 to March 31, 2021, from complete sequences with a known collection date deposited in GISAID. Table 1 lists the signature mutations for the variants. Table 2 shows the total number of complete sequences each variant of interest (B.1.1.7 (the UK variant), 501Y.V2 (the South African variant) and 484K.V2 (B.1.1 lineage with S: E484K/D614G, V1176F N: A199S/R203K/G204R) deposited in GISAID by each country as of March 31, 2021. |
