Coronavirus SL-III cis-acting replication element (CRE)
Encyclopedia
The coronavirus SL-III cis-acting replication element (CRE) is an RNA element
that regulates defective interfering (DI) RNA replication.
Other RNA families identified in the coronavirus include the coronavirus 3' stem-loop II-like motif (s2m)
, the coronavirus frameshifting stimulation element
, the coronavirus packaging signal
and the coronavirus 3' UTR pseudoknot
.
Cis-regulatory element
A cis-regulatory element or cis-element is a region of DNA or RNA that regulates the expression of genes located on that same molecule of DNA . This term is constructed from the Latin word cis, which means "on the same side as". These cis-regulatory elements are often binding sites for one or...

Coronavirus 3' stem-loop II-like motif (s2m)
The Coronavirus 3' stem-loop II-like motif is a secondary structure motif identified in the 3'untranslated region of astrovirus, coronavirus and equine rhinovirus genomes...

Coronavirus frameshifting stimulation element
In molecular biology, the coronavirus frameshifting stimulation element is a conserved stem-loop of RNA found in coronaviruses that can promote ribosomal frameshifting. Such RNA molecules interact with a downstream region to form a pseudoknot structure; the region varies according to the virus but...

Coronavirus packaging signal
The Coronavirus packaging signal is a conserved cis-regulatory element found in Coronavirus which has an important role in regulating the packaging of the viral genome into the capsid....

Coronavirus 3' UTR pseudoknot
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...
