The Coronavirus 3′ UTR pseudoknot is an RNA structure found in the coronavirus genome. Coronaviruses contain 30 kb single-stranded positive-sense RNA genomes. The 3′ UTR region of these coronavirus genomes contains a conserved ~55 nucleotide pseudoknot structure which is necessary for viral genome replication.[1] The mechanism of cis-regulation is unclear, but this element is postulated to function in the plus-strand.
Other RNA families identified in the coronavirus include the coronavirus frameshifting stimulation element, the coronavirus 3′ stem-loop II-like motif (s2m) and the coronavirus packaging signal.
