ORF1ab (also ORF1a/b) refers collectively to two open reading frames (ORFs), ORF1a and ORF1b, that are conserved in the genomes of nidoviruses, a group of viruses that includes coronaviruses. The genes express large polyproteins that undergo proteolysis to form several nonstructural proteins with various … See more ORF1a is the first open reading frame at the 5' end of the genome. Together ORF1ab occupies about two thirds of the genome, with the remaining third at the 3' end encoding the structural proteins and accessory proteins. … See more Core replicase domains A set of five conserved "core replicase" protein domains are present in all nidovirus lineages (arteriviruses, mesoniviruses, roniviruses, … See more The polyproteins pp1a and pp1ab contain about 13 to 17 nonstructural proteins. They undergo auto-proteolysis to release the nonstructural proteins due to the actions of internal cysteine protease domains. In coronaviruses, … See more The structure and organization of the genome, including ORF1a, ORF1b, and the frameshift separating them, is conserved among nidoviruses. Some "non-canonical" nidovirus structures have been described, mainly involving gene fusions. The largest known nidovirus, See more WebDec 1, 2024 · A Ct-value of 37 to<40 required confirmation by retesting. The sampling time between the two test specimens was at least 24 h. ... ORF1ab may make the detection of the N gene more stable than that of ORF1ab, which could partially explain why the N gene, rather than ORF1ab, was detected more often in the repositive and last-positive test results
