(Submitter supplied) Post-transcriptional modifications of mRNA have emerged as novel regulators of gene expression. Pseudouridylation is the most abundant and widespread type of RNA modification in living organisms; however, the biological role of pseudouridine in mRNAs remains poorly understood. Here, we show that the pseudouridine synthase dyskerin associates with RNA polymerase II and is enriched at RNA polymerase II-transcribed genes genome-wide. more...

(Submitter supplied) Dyskeratosis congenita is a bone marrow failure syndrome characterized by the presence of short telomeres at presentation. The X-linked form is caused by mutations in the gene DKC1, encoding the protein dyskerin. Dyskerin is required for in the assembly and stability of telomerase and is also involved in ribosomal RNA (rRNA) processing where it converts specific uridines to pseudouridine. DC is thought to result from failure to maintain tissues, like blood, that are renewed by stem cell activity, suggesting induced pluripotent stem (iPS) cells from X-linked DC patients may provide information about the mechanisms involved. more...

(Submitter supplied) Pseudouridine is the most abundant modification occurring on RNA, yet with the exception of a few well-studied RNA molecules little is known about the modified positions and their function(s). Here, we develop Ψ-seq, a method for transcriptome-wide quantitative mapping of pseudouridine. We validate Ψ-seq with synthetic spike-ins and de novo identification of the vast majority of previously reported pseudouridylated positions. more...

(Submitter supplied) Mutations in genes encoding components of the telomerase holoenzyme complex result in a spectrum of rare genetic disorders known as telomere diseases, including dyskeratosis congenita (DC). A consistent finding in DC due to pathogenic mutations in DKC1, which encodes dyskerin, is decreased steady-state levels of the non-coding RNA component of telomerase (TERC) and thus impaired telomere maintenance. more...

(Submitter supplied) We report the development of Pseudo-Seq, a sequencing based technique for identification of pseuoduridine (Ψ) modifications within RNA. We performed Pseudo-Seq on S. cerevisiae and HeLa cells and find the first evidence for pseusouridylation of endogenous mRNAs.

(Submitter supplied) Pseudouridine (Ψ) is an abundant post-transcriptional RNA modification in ncRNA and mRNA. However, transcriptome-wide measurement of individual Ψ sites remains unaddressed. Here, we develop “PRAISE”, via selective chemical labeling of Ψ by bisulfite to induce nucleotide deletion signature during reverse transcription, to realize quantitative assessment of the Ψ landscape in the human transcriptome. Unlike traditional RNA/DNA bisulfite treatment, our approach is based on quaternary base mapping and identifies 2,209 confident Ψ sites in HEK293T cells. By perturbing pseudouridine synthases, we obtained differential mRNA targets of PUS1, PUS7, TRUB1 and DKC1. In addition, we identified known and novel Ψ sites in mitochondrial mRNA, which are catalyzed by a mitochondria-localized isoform of PUS1. Collectively, we provide a reliable, sensitive and convenient method to quantify transcriptome-wide Ψ; we envision this approach would facilitate emerging efforts to elucidate the function and mechanism of mRNA pseudouridylation.

(Submitter supplied) We performed pseudouridine profiling (Pseudo-seq) on 11 biological replicates of chromatin-associated RNA. We performed mRNA-seq of PUS1 knockout, PUS7 knockdown, RPUSD4 knockdown and wildtype HepG2 cells. We used an in vitro pool based strategy to assign pre-mRNA targets to individual human pseudouridine synthases (PUS) .
