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 Steve Shen,Zhao Zhang,Funan He
Evidence Using the seafood market workers SARS-CoV-2 sequence (EPI_ISL_402125 and NC_045512) as the reference, we found nine major recurrent mutations in the NCBI dataset (Table 4 ). These mutations can classify most SARS-CoV-2s in NCBI dataset into six groups (Fig. 4).
