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.

Evidence We identified 115 mutations with NRFp>0.03 (Fig. S1); this means that those mutations are estimated to be present in more than 3% of the COVID-19 cases globally. Considering that the sum of the reported cases from the 714 country-month combinations analyzed was 120,008,410 cases, an NRFp of more than 0.03 means that those mutations were present in more than 3,600,252 global COVID-19 cases.
