N2,N2-Dimethylguanosine is a methylated nucleoside found in RNA and serves as a structural modification component of tRNA. It obstructs reverse transcriptase-mediated cDNA synthesis and is a crucial modification impacting sequencing efficiency in high-throughput RNA sequencing. This compound can selectively remove one of its methyl groups via AlkB mutant enzymes (such as D135S/L118V), converting it into N2-methylguanosine, which subsequently reduces hindrance to reverse transcription.
- Found in RNA
- Structural modification component of tRNA
- Obstructs reverse transcriptase-mediated cDNA synthesis
- Impacts sequencing efficiency in high-throughput RNA sequencing
