You might have noticed some additional information on the mature miRNA pages in the last few weeks. See for example: http://mirbase.org/cgi-bin/mature.pl?mature_acc=MIMAT0000123 http://mirbase.org/cgi-bin/mature.pl?mature_acc=MIMAT0000069 The new section “QuickGO function” contains a set of high quality manual annotations of Gene Ontology terms for mature mi […]

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 […]

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 […]

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 […]
