(Submitter supplied) Despite its biological importance, transfer RNA (tRNA) could not be adequately sequenced due to the abundant presence of post-transcriptional modifications and extensive structure that interfere with cDNA synthesis and adapter ligation. We achieve efficient and quantitative tRNA sequencing by removing base methylations using engineered demethylases and using a highly processive thermo-stable reverse transcriptase without the need for adapter ligation (DMTRT-tRNA-seq). more...

(Submitter supplied) We report the identification and quantification of Watson-Crick modifications in tRNA and rRNA through the use of high throughput sequencing. We apply the recently published DM-tRNA-Seq method to generate demethylase treated and untreated 293T samples, and using computational methods we are able to flag sites using a modification index. This index allows us to generate site-resolved information about modification that we can use to identify and quantify Watson-Crick face modifications in tRNA and rRNA. more...

(Submitter supplied) Here we develop a high throughput sequencing method that enables accurate determination of charged tRNA fractions at single base resolution (Charged tRNA-seq). Our method takes advantage of the recently developed DM-tRNA-seq method, but includes additional chemical steps that specifically remove the 3'A residue in the uncharged tRNA. Charging fraction is obtained by counting the fraction of A-ending reads versus A+C-ending reads for each tRNA species. more...

(Submitter supplied) tRNAs are subject to numerous modifications including methylation. Mutations in the human N7-methylguanosine (m7G) methyltransferase complex METTL1-WDR4 cause primordial dwarfism and brain malformation yet the molecular and cellular function in mammals is not well understood. We developed m7G methylated tRNA immunoprecipitation sequencing (MeRIP-Seq) and tRNA reduction and cleavage sequencing (TRAC-Seq) to reveal the m7G tRNA methylome in mouse embryonic stem cells (mESCs). more...

(Submitter supplied) Queuosine (Q) is a conserved tRNA modification at the wobble anticodon position of tRNAs that read the codons of amino acids Tyr, His, Asn, and Asp. Q-modification in tRNA plays important roles in the regulation of translation efficiency and fidelity. Queuosine tRNA modification is synthesized de novo in bacteria, whereas the substrate for Q-modification in tRNA in mammals is queuine, the catabolic product of the Q-base of gut bacteria. more...

(Submitter supplied) High-throughput sequencing of cellular tRNAs is severely hindered by the presence of base modifications. These modifications impair the reverse transcription (RT) enzyme and prevent a large fraction of transcripts to be converted into cDNA in conventional sequence library preparation. Recent attempts to circumvent this issue made use of enzymatic treatments to remove methyl groups (Cozen et al. 2015; Zeng et al. more...

Here using high-throughput sequencing, sites and frequency of tRNA modifications are predicted in Vibrio cholerae and Escherichia coli. During cDNA synthesis, some modifications cause misincorporation of a wrong base or termination of reverse transcription (RT). more...

(Submitter supplied) The post-transcriptional modification of mRNA and tRNA provides an additional layer of regulatory complexity during gene expression. TRMT10A is a tRNA methyltransferase that installs N1-methylguanosine (m1G), while FTO performs demethylation on N6-methyladenosine (m6A) and N6,2'-O-dimethyladenosine (m6Am) in mRNA. We find that this tRNA methyltransferase TRMT10A interacts with mRNA demethylase FTO (ALKBH9), both in vitro and inside cells. more...

(Submitter supplied) N7-methylguanosine (m7G) is a positively charged, essential modification at the 5′ cap of eukaryotic mRNA, regulating mRNA export, translation, and splicing. m7G also occurs internally within tRNA and rRNA, but its existence and distribution within eukaryotic mRNA remain to be investigated. Here, we show the presence of internal m7G sites within mammalian mRNA. We then performed transcriptome-wide profiling of internal m7G methylome using m7G-MeRIP sequencing (MeRIP-seq). more...

(Submitter supplied) N1-methyl adenosine (m1A) is a wide-spread RNA modification present in tRNA, rRNA and mRNA. m1A modification sites in tRNAs are evolutionary conserved and its formation on tRNA is catalyzed by methyltransferase TRMT61A and TRMT6 complex. m1A promotes translation initiation and elongation. Due to its positive charge under physiological conditions, m1A can notably modulate RNA structure. It also blocks Watson-Crick base pairing and causes mutation and truncation during reverse transcription. more...

(Submitter supplied) The surprising observation that virtually the entire human genome is transcribed means we know very little about the function of many emerging classes of RNAs, except their astounding diversity. Traditional RNA function prediction methods rely on sequence or alignment information, which are limited in their ability to classify classes of non-coding RNAs (ncRNAs). To address this, we developed CoRAL, a machine learning-based approach for classification of RNA molecules. more...
