RNA modifications play important roles in gene expression regulation. CD Genomics provides m7G + m3C sequencing service for the simultaneous identifications of 7-methylguanosine (m7G) and 3-methylcytidine (m3C) in RNA including both known and previously unmapped positions at single nucleotide resolution.
Chemical RNA modifications as central features of epitranscriptomics are highlighted by the discovery of modified ribonucleosides in mRNA and non-coding RNAs and exemplified by the vital roles of RNA modifications in normal physiology and disease. Methylation of guanosine on position N7 (m7G) on RNA has been found on various types of RNA molecules including mRNA 5’ cap structure, internal mRNA regions, pri-miRNA, tRNA and rRNA. m7G modifications play critical roles in mRNA transcription, miRNA biogenesis and functions, tRNA stability, and 18S rRNA maturation. The m7G RNA methylation has become a hot research topic in recent years. The m3C RNA methylation has been discovered on mRNAs, tRNAs, and rRNAs, however, the biochemistry of m3C formation in mammalian RNA and its functions are still poorly understood. To expand the list of NGS-detectable RNA modifications, CD Genomics has developed multiple products targeting m7G/m3C methylation. We also provide one-stop m7G+m3C RNA methylation sequencing services, simultaneously detecting global m7G and m3C methylations present in mRNA, lncRNA, pri-miRNA, tRNA, rRNA and other RNA molecules at single base resolution. Additionally, we provide m7G MeRIP-Seq for profiling global m7G modification sites. CD Genomics will gladly support your epitranscriptomics projects with challenging or unusual requirements.
