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.
