ORF3a (previously known as X1 or U274) is a gene found in coronaviruses of the subgenus Sarbecovirus, including SARS-CoV and SARS-CoV-2. It encodes an accessory protein about 275 amino acid residues long, which is thought to function as a viroporin. It is the largest accessory protein and was the first … Zobacz więcej ORF3a is well conserved within the subgenus Sarbecovirus. The protein has 73% sequence identity between SARS-CoV (274 residues) and SARS-CoV-2 (275 residues). Within the ORF3a open reading frame there … Zobacz więcej The ORF3a protein does not appear to be essential for viral replication. From studies with SARS-CoV, there is conflicting evidence on whether or not its deletion reduces replication efficiency. Viroporin The ORF3a … Zobacz więcej The ORF3a protein is a transmembrane protein that contains three transmembrane domains. It has an N-terminal ectodomain and Zobacz więcej Along with the genes for other accessory proteins, the ORF3a gene is located near those encoding the structural proteins, at the 3' end of the coronavirus RNA genome. ORF3a is located between the spike (S) and envelope (E) genes. ORF3a is expressed from … Zobacz więcej Witryna21 kwi 2024 · With further analysis, the scientists confirmed that, unlike IBV envelope protein, the ion channel activity of SARS-CoV-1 ORF3a protein is required for the …
