In silicoidentification of conservedcis-acting RNA elements in the SARS-CoV-2 genome
Abstract
Aim
The aim of this study was to computationally predict conserved RNA sequences and structures known ascis-acting RNA elements (CREs) located within the SARS-CoV-2 genome.
Materials & methods
Bioinformatics tools were used to analyse and predictcis-acting regulatory elements by obtaining viral sequences from available databases.
Results
Computational analysis prediction revealed the presence of RNA stem-loop structures within the 3’ end of the ORF1ab region that are analogous to the previously identified SARS-CoV genomic packaging signals. Alignment-based RNA secondary structures prediction of the 5’ end of the SARS-CoV-2 genome identified also conserved CREs.
Conclusion
These CREs could be used as potential targets for a vaccine and/or antiviral therapeutics developments; however, further studies would be required to confirm their roles in the SARS-CoV-2 life cycle.
