  • The landscape of RNA modifications from high-throughput sequencing data

    We're pleased to announce the release of the RMBase (RNA Modification Base) for decoding the landscape of RNA modifications identified from 404 high-throughput sequencing data (Pseudo-seq, Ψ-seq, CeU-seq, Aza-IP, MeRIP-seq, m6A-seq, miCLIP, m6A-CLIP, RiboMeth-seq).

    It contains ~124200 N6-Methyladenosines (m6A), ~9500 pseudouridine (Ψ) modifications, ~1000 5-methylcytosine (m5C) modifications, ~1210 2′-O-methylations (2′-O-Me) and ~3130 other types of RNA modifications.

    RMBase demonstrated thousands of RNA modifications located within regulatory RNAs (e.g. mRNAs, lncRNAs, miRNAs, pseudogenes, circRNAs, snoRNAs etc.), miRNA target sites and disease-related SNPs.

    We hope this platform will greatly help biologists to explore the prevalence, mechanism and function of various RNA modifications and link them with human cancers and other diseases.

    RMBase is freely available at http://rna.sysu.edu.cn/rmbase/. We are looking forward to hearing your feedback!

    RMBase paper is available at http://nar.oxfordjournals.org/content/44/D1/D259

    about 101,780 novel m6A modification sites from 4 studies (m6A-CLIP, m6A-Seq technologies) have been added into RMBase.

      recently, one Nature paper and one Nature Chemical biology paper have identified dynamic N1-methyladenosine (m1A) methylome in the message RNAs (mRNAs) using newly developed sequencing approaches. these modifications indicate a functional role for m1A in promoting translation of methylated mRNA.

      (2) Transcriptome-wide mapping reveals reversible and dynamic N1-methyladenosine methylome.Nat Chem Biol. 2016 Feb 10.

      This datasets will be added into RMBase.

        RNA modification Database and RNA-Binding Protein Binding Sites

        Recently, we integrated thousands of RNA-Binding Proteins (RBP) binding sites identified from CLIP-Seq experiments and performed relationship analysis of RBP binding regions and RNA modifications. RMBase demonstrated thousands of RNA modifications located within RNA-Binding Proteins (RBPs) regions and revealed that RNA modifications may influence the function of RBP or the RBP may catalyse the RNA modification.

        You can browse various RNA modifications within the RNA-Binding Proteins (RBPs) Binding sites with follow website: http://rna.sysu.edu.cn/rmbase/modRBP.php

              Current Approaches to Protein Sequencing
              by seqadmin


              Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...

              Strategies for Sequencing Challenging Samples
              by seqadmin


              Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
