Protein detail:
| Protein name | ORF3a protein |
| Uniprot protein ID | P0DTC3 |
| Protein length | 275 amino acids |
| Protein description | ORF3a is a non-structural protein of SARS-CoV-2 localized at the surface. It is the largest accessory factor that contains 275 amino acids, and shows broad functions, such as enhancing viral entry within the host, regulating the pro-inflammatory cytokine and chemokine production, participating in ion channel formation as well as modulating release of virus from the host cell. |

| Author | Martina Bianchi,a Alessandra Borsetti,b Massimo Ciccozzi,c and Stefano Pascarellaa, |
| Evidence | Ten of the seventeen mutant sites occur within the transmembrane (TM) domain of ORF3a and are in contact with the central pore or side tunnels. The other variant sites are in different places of the ORF3a structure. Within the entire sample, the five most frequent mutations are V13L, Q57H, Q57H + A99V, G196V and G252V. |
