  • MicroRNA Gene Ontology annotations June 7, 2018
    You might have noticed some additional information on the mature miRNA pages in the last few weeks. See for example: The new section “QuickGO function” contains a set of high quality manual annotations of Gene Ontology terms for mature mi […]
  • miRBase 22 release March 12, 2018
    After repeated and unreasonable delay, miRBase 22 is finally released. As you might expect with such a long gap, the number of sequences in the database has jumped significantly — by over a third. The vast majority of the increase comes from new microRNA annotations in species not previous represented in the database. Indeed, there […]
  • High confidence miRNA set available for miRBase 21 July 3, 2014
    As mentioned previously, we briefly held off from releasing the set of “high confidence” miRNAs for miRBase 21, because of a last-gasp bug. Those data are now available, tagged with the label “high confidence” on the entry pages, and for download on the FTP site. The total number of miRNAs labelled “high confidence” has increased […]
  • miRBase 21 finally arrives June 26, 2014
    Apologies for the longer-than-usual wait. miRBase 21 is now available on the website, and all data available for download on the FTP site. As usual, the release notes describe the major changes. Of particular note this time, the Genome Reference Consortium have released a new human genome assembly, GRCh38. We have therefore remapped the human […]
