  • non-coding RNA database

    Hi,

    Do anybody know any website or ftp link that able to download all the non-coding RNA database of all species?

    The link below got non-coding RNA database:


    Unfortunately, it not allow to download all the non-coding RNA database at the same time.

    Thanks for any advice.

    It'd be nice if that was possible. People often use Rfam for this. However it is not designed to be a complete resource of ncRNA sequences across all species.

    There is a proposal to create a resource (RNAcentral) along these lines.

      miRNA sequences obtained from release of miRBase (release 8.2, July 2006)

      It's long time no upadte.

        The Silva database is a fairly comprehensive database of non-coding RNA (at least in terms of the most common ncRNA you'll see in RNASeq data):

          I have found the UCSC mirror at http://www.ncrna.org useful.

            Many thanks, ppgardne.
            I just download Rfam database.
            Silva database suggested by gringer looks quite comprehensive of non-coding RNA sequence

              Thanks, gringer.
              I'm further exploring Silva database to download all non-coding RNA sequence in all species.
              Do you got any idea that whether non-coding RNA sequence in Silva database also available and published in NCBI?
              Thanks for advice.

                Hi, polyatail.
                It seems like the link http://ncrna.org is broken?
                I fail to access it
                Thanks.

                  Just in case it wasn't apparent, Silva is only a rRNA database. I'm not sure how it compares in size to other databases.

                    We were using sequences downloaded from Silva to screen RNAseq data sets for rRNA. Worked pretty well most of the time. However, it turns out that they have very limited animal (including arthropods) mitochondrial rRNAs. As these apparently are sometimes poly adenylated (in oysters, I think), they are potentially a major source of ncRNA in a RNAseq dataset.

                    Anyway, looks like there is a set of ncRNAs here. It even includes some non-ribosomal ncRNAs. (Mainly tRNAs.) Specifically it does include animal SSU and LSU mitochondrial rRNAs.

                      At this point Biomart is the most comprehensive service to download all non-coding data for multiple organisms. The non-coding RNA are classified into various sub.-categories which have to selected together for each organism.

                        Essential Discoveries and Tools in Epitranscriptomics
                        by seqadmin




                        The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...

                        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...
