2'-Omethyl RNA Bases

RNA, as an important research tool, is widely used in the analysis of gene function and the development of novel therapeutic strategies. BOC RNA has advanced international high-throughput DNA synthesizers, professional technicians and mature synthetic purification methods to provide you with high-quality, multi-kind RNA synthesis services in a timely manner.

RNA Modification

RNA modification refers to covalent modification on RNA, such as m6A (methylation of position 6 N on adenine). In addition, various complex covalent modifications on tRNA, or cap sequence m7G on mRNA (methylation of position 7 N on guanine) are also RNA modifications. RNA modification can regulate RNA translation and change RNA stability.

2'-O-methylation

2′-O-methylation (2′-O-M) is a chemical modification of ribose RNA methylation at the 2' position under the action of RNA methylase or fibrinase. 2′-O-methylation modifications are common in rRNAs and snRNAs associated with translational and RNA shear functions, and also in mRNA, tRNA, snoRNA and siRNA, and in the four bases of A, U, C and G in both three-domain organisms and viral RNA. Studies have shown that 2′-O-methylation affects mRNA binding to protein, regulates rRNA translation efficiency and participates in tRNA recognition. More than 1200 2'-O-methylation sites have been identified in mammals and yeast.

2'-Omethyl Bases

2'-Omethyl bases are classified as 2'-Omethyl RNA monomers. When no specific 2'-OH is required, 2'-Omethyl nucleotides are most commonly used to give nuclease resistance to oligonucleic acids designed for antisense, siRNA, or aptamer-based research, diagnosis, or treatment purposes. Nuclease resistance can be further enhanced by phosphothiolation of appropriate inter-nucleotide linkages within the oligonucleotide.

2'-Omethyl modification is a form of natural modification that occurs after transcription of small RNA (e.g. tRNA), which increases RNA: RNA double-stranded Tm, but causes only minor changes in RNA: DNA hybrid strand stability. It is typically 5 to 10 times less sensitive to DNA enzymes than DNA and can be partially resistant to a variety of ribonucleases and deoxyribonucleases. It is commonly used in antisense experiments to increase stability as well as binding affinity to the target.
