Quantitative RNA pseudouridine maps reveal multi-layered translation control through plant rRNA, tRNA and mRNA pseudouridylation in maize

ABSTRACT: Pseudouridine (Ψ) is the most abundant RNA modification, yet studies of Ψ has been hindered by the lack of robust methods to profile Ψ and comprehensive Ψ maps. In this study, we utilize BID-seq, a newly developed Ψ sequencing method, to generate transcriptome-wide Ψ maps at single-base resolution across various plant species and tissues

BID-seq for transcriptome-wide quantitative sequencing of mRNA pseudouridine at base resolution

Project description:Pseudouridine (Ψ) is an abundant RNA modification that is present in and impacts the functions of diverse non-coding RNA species, including rRNA, tRNA, snRNA, etc. Pseudouridine also exists in mammalian mRNA and likely exhibits functional roles; however, functional investigations of pseudouridine in mammalian mRNA have been hampered by the lack of a quantitative method that detects Ψ at base precision. We have recently developed Bisulfite-Induced Deletion sequencing (BID-seq), which provides the community with a quantitative method to map RNA Ψ distribution transcriptome-wide at single-base resolution. Here, we describe an optimized BID-seq protocol to generate highly reproducible results, displaying nearly zero background deletions at unmodified uridines after bisulfite treatment and uncovering 8,407 Ψ sites starting from as little as 10 ng mouse embryonic stem cell (mESC) polyA+ RNA, with the steps that are fast in both library preparation and data analysis. This optimized BID-seq workflow takes 5 days to complete and includes four main sections: RNA preparation, library construction, next-generation sequencing (NGS), and data analysis. The library construction can be completed by researchers who have basic knowledge and skills in molecular biology and genetics. In addition to the experimental protocol, we provide BID-pipe (https://github.com/y9c/pseudoU-BIDseq), a user-friendly data analysis pipeline for BID-seq, requiring only basic bioinformatic and computational skills to uncover Ψ signatures from NGS data.

Quantitative sequencing using BID-seq uncovers abundant pseudouridines in mammalian mRNA at base resolution

Project description:Functional characterization of pseudouridine (Ψ) in mammalian messenger RNA (mRNA) has been hampered by the lack of a quantitative method that maps pseudouridine in the whole transcriptome. We report bisulfite-induced deletion sequencing (BID-seq) that utilizes a bisulfite-mediated reaction to stoichiometrically convert pseudouridine into deletion upon reverse transcription. BID-seq enabled detection of abundant pseudouridine sites with stoichiometry information in several human cell lines and 12 different mouse tissues using 10-20 ng input RNA. We uncovered consensus sequences for pseudouridine in mammalian mRNA and assigned different ‘writer’ proteins to individual pseudouridine deposition. Our results reveal a transcript stabilization role of Ψ sites installed by TRUB1 in human cancer cells. We also detected presence of Ψ within stop codons of mammalian mRNA, and confirmed the role of Ψ in promoting stop codon read-through in vivo. This new method for sensitive and comprehensive detection of Ψ sets the stage for future investigations of the roles of Ψ in diverse biological processes.

Differential roles of human PUS10 in miRNA processing and tRNA pseudouridylation

Project description:Pseudouridine synthases (PUSs) are responsible for the installation of pseudouridine (Ψ) modification in RNA. However, the activity and function of the PUS enzymes remain largely unexplored. Here we focus on human PUS10 and find that it co-expresses with the microprocessor (DROSHA–DGCR8 complex). Depletion of PUS10 results in a marked reduction of the expression level of a large number of mature miRNAs and concomitant accumulation of unprocessed primary microRNAs (pri-miRNAs) in multiple human cells. Mechanistically, PUS10 directly binds to pri-miRNAs and interacts with the microprocessor to promote miRNA biogenesis. Unexpectedly, this process is independent of the catalytic activity of PUS10. Additionally, we develop a sequencing method to profile Ψ in the tRNAome and report PUS10-dependent Ψ sites in tRNA. Collectively, our findings reveal differential functions of PUS10 in nuclear miRNA processing and in cytoplasmic tRNA pseudouridylation.
