Protein detail:
| Protein name | ORF8 protein |
| Uniprot protein ID | P0DTC8 |
| Protein length | 121 amino acids |
| Protein description | The SARS-CoV-2 ORF8 gene spans 366 nucleotides (nt), is located between position 27,894 and 28,259 of the virus genome, following the ORF7b and preceding the N genes, respectively. The ORF8 gene is part of a hypervariable genomic region of - 430 bp in length that has been recognized as a recombination hotspot, also highly susceptible to deletions and nt substitutions. ORF8 protein comprehends an N-terminal signal peptide for transmembrane (TM) import and secretion, an internal -sandwich core and a C-terminal TM region followed by a stretch of basic residues. |

| Title | Dynamics of severe acute respiratory syndrome coronavirus 2 genome variants in the feces during convalescence |
| Author | Yi Xu,Lu Kang,Zijie Shen,Xufang Li,Weili Wu, |
| Evidence | We identified 229 intra-host variants at 182 sites in 18 fecal samples. Among them, nineteen variants presented frequency changes > 0.3 within 1-5 days, reflecting highly dynamic intra-host viral populations.(Figure3) |
