Abstract: RNA-targeting therapeutics require highly efficient sequence-specific devices capable of RNA irreversible degradation in vivo. The most developed methods of sequence-specific RNA cleav- age, such as siRNA or antisense oligonucleotides (ASO), are currently based on recruitment of either intracellular multi-protein complexes or enzymes, leaving alternative approaches (e.g., ribozymes Citation: Staroseletz, Y.; Gaponova, and DNAzymes) far behind. Recently, site-selective artificial ribonucleases combining the oligonu- S.; Patutina, O.; Bichenkova, E.; cleotide recognition motifs (or their structural
