m1A sequencing is a next generation sequencing (NGS)-based method to comprehensively detect m1A, a newly discovered RNA methylation, at single nucleotide resolution. It can quickly identify the complete picture of the m1A modification in transcripts. Our experienced technical team provides you with integrated m1A sequencing service and professional data analysis.
N1-methyladenosine (m1A), occurs mainly in thousands of different gene transcripts in eukaryotic cells (from yeast to mammals). It is a post-transcriptional modification with high abundance in tRNA and rRNA in eukaryotes and most m1A methylation modifications occur in the 5'UTR region of mRNA. m1A at the first and second nucleotide of the transcript can promote mRNA translation, while m1A in the coding region can inhibit translation. Recent studies have also shown m1A plays an active and dynamic role in the initiation of translation in mammalian cells. m1A can regulate the intensity of specific translation initiation sites, thereby affecting the balance between alterative initiation sites and canonical initiation sites. m1A sequencing (m1A-seq), a technology relying on the immunoprecipitation of RNA fragments carrying m1A, provides an overview of m1A modifications. The principle is to co-incubate randomly interrupted RNA fragments with m1A RNA methylation-specific antibodies and capture methylated fragments followed by deep sequencing to provide complete maps of m1A sites in the transcriptome. m1A-seq can reveal the occurrence of m1A methylation in RNAs at high detection rate, enabling a more comprehensive understanding of transcription and translation of mRNA, structure and function of tRNA and rRNA. In particular, m1A-seq helps us to further understand the role and function of this novel epigenetic transcriptome marker.
