m1A Post‐Transcriptional Modification in tRNAs [PDF]
Biomolecules, 2017 To date, about 90 post‐transcriptional modifications have been reported in tRNA expanding their chemical and functional diversity. Methylation is the most frequent post‐transcriptional tRNA modification that can occur on almost all nitrogen sites of

m1A methylation modification patterns and metabolic characteristics in hepatocellular carcinoma [PDF]
BMC Gastroenterology, 2022 Background The dysregulation of RNA methylation has been demonstrated to contribute to tumorigenicity and progression in recent years. However, the alteration of N1-methyladenosine (m1A) methylation and its role in hepatocellular carcinoma (HCC) remain ...

m1A RNA Modification in Gene Expression Regulation
Genes, 2022 N1-methyladenosine (m1A) is a prevalent and reversible post-transcriptional RNA modification that decorates tRNA, rRNA and mRNA. Recent studies based on technical advances in analytical chemistry and high-throughput sequencing methods have revealed the crucial roles of m1A RNA modification in gene regulation and biological processes. In this review, we

N 1-methyladenosine (m1A) RNA modification: the key to ribosome control [PDF]
Journal of Biochemistry, 2020 AbstractRNA displays diverse functions in living cells. The presence of various chemical modifications of RNA mediated by enzymes is one of the factors that impart such functional diversity to RNA. Among more than 100 types of RNA modification, N1-methyladenosine (m1A) is found mainly in tRNA and rRNA of many living organisms and is known to be deeply ...

The Impact of m1A Methylation Modification Patterns on Tumor Immune Microenvironment and Prognosis in Oral Squamous Cell Carcinoma [PDF]
International Journal of Molecular Sciences, 2021 N1-methyladenosine (m1A) modification widely participates in the occurrence and progression of numerous diseases. Nevertheless, the potential roles of m1A in the tumor immune microenvironment (TIME) are still not fully understood. Based on 10 m1A methylation regulators, we comprehensively explored the m1A modification patterns in 502 patients with oral

Reversible RNA Modification N1-methyladenosine (m1A) in mRNA and tRNA
Genomics, Proteomics & Bioinformatics, 2018 More than 100 modifications have been found in RNA. Analogous to epigenetic DNA methylation, epitranscriptomic modifications can be written, read, and erased by a complex network of proteins.

A primordial RNA modification enzyme: the case of tRNA (m1A) methyltransferase [PDF]
Nucleic Acids Research, 2004 The modified nucleoside 1-methyladenosine (m(1)A) is found in the T-loop of many tRNAs from organisms belonging to the three domains of life (Eukaryota, Bacteria, Archaea). In the T-loop of eukaryotic and bacterial tRNAs, m(1)A is present at position 58, whereas in archaeal tRNAs it is present at position(s) 58 and/or 57, m(1)A57 being the obligatory ...
